GPU randomly buzzing even on IDLE
- Thread starter DV2FOX
- Start date
If its caused by interference being produced by the AC you could try to clean the electrical power to the PC.
You could try power conditioners that filter out EMI and smooth spikes (without the battery backup part found in a UPS). High-end EMI/RFI filtering power strips with filtering circuitry superior to a standard supermarket surge protector. And also ferrite beads (RF Chokes), which you clip around power cables to the PC or the air conditioner, that suppress electromagnetic noise traveling through the wires (you've likely seen these on some electrical cables.

Nono, i mean. This entire topic happens without the specific ACs being turned on, and we already tried an EMI filter or similar along the USP thing, wich seemed to stop the noise from the PSU but transferred it to the UPS instead (and obviously we returned it)
Same goes with the black cylinders that ya put around the PSU's wall socket cable to no avail
This morning i woke up and didnt heard the ringing in my left ear (being exposed to it makes it happen still for a while even with the PC turned off) meaning it was a good chance to do a cable discarding before going to work, so i disconnected all the PC's fans (rear fan on CHA FAN 1 near the CPU's left, front fans connected to the tower's own PWM FAN HUB at the front grill inside the tower's sideby disconnecting the I/O cable, read below) minus the CPU one, along the HD AUDIO and single USB 3.2 cable and the I/O cable from the tower (can still turn on the PC like that, just disables fans and the bright front LEDs minus the power one wich is 50% lighted up)
I powered on the PC and the noise was like 95% gone from the sitting position (PC under the desk, next to my legs' right side)
A tiny bit of noise came from the PSU but only if i sticked my left ear to it (for some reason the right ear doesnt detects it). Maybe it also came from the VRM area, wich is the 2nd source of electric noise, along the GPU's buzzing on IDLE being random (now i do it, now i dont...Now i stop for a while...). Another source of noise is the PCH FAN area making weird rattling noises or some electrix resonance, but if i control the fan via Fan Control the fan's noise is different so maybe there's something wrong with the chipset too, even tho the PC is stable .
To begin the testings first i connected the rear fan to the header next to the CPU's left. It kinda increased the noise a tiny bit but from the PSU's side. Next the HD AUDIO. Nothing. Then the USB 3.2, wich increased a tad bit, even from the distance. This is kinda intensed around the tower's I/O at the front of the tower, maybe from the light or PCB
Things seems to increase more if i connect the I/O power cable to the PSU with the lights turned on
My thoughts are:
-Since changing the CPU cooler to the NH-U12A CB and with the whole "brackets lightly dragged around the MB and also lightly hit some capacitors/black cylinders" that the motherboard got affected and its noises around the VRM area is affecting everything connected to it, PSU and fans included. (Altho i gotta re-check the fans part...)
And no, changing to my previous NH-D15 CB doesnt solves the issue
-The tower itself is having some electricity malfunction , even tho it's pins etc have been cleaned from dust with a canned air duster (unless i should clean the pins with something else?)
-There's something else that's making this annoying noise
What do you think i should do next?. Change the motherboard to another X570 or even go X870 (Altho there's the whole AMD dead CPUs no matter the MB brand, etc)
Dont think that the PSU could be the reason and even changing the 4070 to a 2070 still does GPU buzzings, so it has to be the motherboard...But what if i change it and the issue persists?. Would it be the tower all along even if after all this time nothing bad happened to it?

It does appear to sound power related in some way. Are all the power cables seated properly on the board/GPU and PSU side? No pins loose in the connectors?
If you're thinking you may have damaged some component on the board, I'd disassemble and inspect. Take out the GPU and CPU cooler and have a good look in bright daylight + torch from different angles.
In fact, I'd probably setup the motherboard outside the case. Disconnect everything, then diligently and carefully reconnect everything up, or start with the bare minimum and test. You may get a better direction/localization by ear being able to move around it more freely. Make sure to ground yourself periodically to prevent static discharge.
Also get someone else to have a listen make sure its not just your left ear, tinnitus or something. It is odd that it's only one ear. Has one or the other ever been damaged in some way compared to the other?

Are you sure it’s not a change in the CPU power state settings that’s causing the hum?
I reduced a lot of chittering that could be confused with GPU coil whine (I mean, it IS coil whine) at idle by turning the C-states off in the BIOS.
Even windows updates might have caused a change to hardware performance.

1. Yes, i never leave anything without being clicked in and gently tight first, specially the GPU connector and YES, i already tried unplugging everything, even rear USBs/cables and then grabbed an air dust can and a new hair drier (Wich's a beast) to remove every bit of dust in the rear and the MB's CPU/24 pin ports etc, trying to be careful with the fans not spinning by the air to prevent mobo issues. Some dust was removed
2. Sadly i don't have any spare thermal paste to do that (Going between coolers etc drained em out). The brackets topic is that when the brackets were being mounted with a hand behind the motherboard's CPU plate they might've waved and fell off the grey cylinders where you screw the brackets, meaning they'd fall around the motherboard or touch the capacitors thingy. They seemed like not moving at all nor affected, only that the VRM area had these sounds, maybe even the PCI slot...
For some reason lately it hasn't happened such electric noises over the VRM area but yes with the GPU,sometimes acting like light coil whine even tho nothing happens to the PC, but if i disconnect the GPU from the PCI slot and turn on the PC, even with the warning noise (Missing GPU in PCI Slot) i don't sense this ringing noise at all (Even tho my left ear has leftovers of such that takes hours to leave, like a temporal tinnitus, luckily...Hopefully...). There's also the GPU sometimes causing what i say "A sound that you can't hear but if you get close to it you can feel some intensity -hurting- your ear". Left ear mainly)
This noise is heard from the GPU but for some reason, altho the following could be kinda related, my CREATIVE PEBBLE V3 speakers makes the same noise only if i stick the left ear to it, on the left speaker, hearing it electrically disrupted but very faintly (Could be my left ear's ringing being "masked" by the static. Speakers' wheel is at 50%). However i can also hear this around the GPU/MB area so...A bit of a gamble (Sure the speakers, since they're BALLS, might've rolled around and caused some light internal damage but to this level?...)
3. That's a good point with the C STATES in BIOS because i already tried that and it reduced the noise. However i am aware that doing that could cause unstability issues so i left it back to ON. Haven''t updated W!0 in a long time (Trying to not enter the messy W11 world , also certain W10 updates broke some lil methods related to notifications, but so far no issues on the actual version.).
As for tinnitus left ear mainly has a "Neeeeeeeeee" light beeping noise that's constant and doesn't varies up. Right ear has a bit of HDD reading noises but also very lightly. For some reason my right ear doesn't have the ringings from the left one but cannot hear them out. Ya can say my ears are very sharp in certain senses (Like i can hear a tiny fan turbulence with my right one but not the left one, while the right one detects actual noise from the MB's chipset's plastic area like it's touching something but the fan ain't running at all (AUTO FAN BTW...I tried Fan Control already and when set to above 40% i can hear the fan but not solving the issue. Something weird's happening over there. Yes, tried using the air can and stuff, some dust came out. Someone said "Try pulling up the plastic because it might feel like the fan's touching something". I did and kinda helped but the noise's still there)
If i turn my head to the left some i hear the chipset area doing some noises so tomorrow i'll try to remove the plastic area by unscrewing the rear of the MB (It'll take a while but i don't want to remove the CPU cooler, no sir, takes time and, again, no thermal paste. MB's chipset is at 60C with fan at 40%

Unfortunately none of use are going to be able to come up with a eureka moment, we are just throwing out guesses in the hopes one lands.
if you want to continue to troubleshoot you'll need to methodically rule causes out. Removing the board (and the cooler), and importantly reassembling from scratch and carefully inspecting for damage or some issue with each component as you go is probably a step you are going to need to take. There's no way your going to be able to inspect the PCB, components and connectors/plugs as thoroughly if leaving it all inside the case. Nor will you be able to localise the sound as well by ear, or rule out some error that was missed. Outside the case will make this easier and more thorough.
That or go straight to trying out a new board and see if that fixes it. Either way if you replace the board or investigate on an open bench outside the case, you'll need new paste. I would order some new paste, set aside a day and start early. Even if I were to buy a new motherboard in the hopes that resolves it, I would also set it up and test it outside the case, before committing to getting it all nicely installed.
It's unlikely to be dust. the compressed air canister is not going to do anything except, best case, maybe blow a loose surface component, screw, debris or whatever about the case to settle elsewhere.
Anyway, some random sunday evening thoughts:
- The speaker sounds environmental, could be simple unrelated RF interference or something else electrical affecting the board>speakers, hard to know..
- Also after bringing it up you then say its not AC related, as yours was off and it still does it. If you live in a flat do other people in the building use AC? You did mention a UPS seemed to help, but transferred the noise instead to the UPS so you got rid of it. Did it resolve this specific issue or did it just quieten the PSU at some earlier time, and this new issue developed later. Maybe get a power conditioner/EMI filtering strip anyway.
- You made a note the tower case I/O seems to contribute, maybe something there. Only connect the power switch, or leave all disconnected and delicately use a metal screwdriver to briefly bridge the pwr pins to power up the PC. Look online if you're unsure what I mean.
- You mention some GPU contribution/differences, old vs new, and suspected your PCI slot. Your board has 2 PCI x16 slots, have you tried the other one.

The following can help reduce EMI Electromagnetic interference and reduce any electronic noise caused sometimes in a system. Also if you have a mobile phone near a computer that can also cause strange noises to appear too.
On the ASUS TUF Gaming X570-Plus, the SB (Southbridge) Clock Spread Spectrum setting is found under Ai Tweaker in Advanced Mode (F7). Disabling this setting (setting to "Disabled") ensures a solid 100MHz base clock (BCLK), which can improve stability and performance, whereas "Auto" or "Enabled" may lock it at 99.8MHz.
Spread Spectrum is a BIOS setting used to reduce electromagnetic interference (EMI) by slightly fluctuating the CPU/system clock (e.g., 100 MHz). It is usually found under Advanced/Tweaker settings. It is recommended to disable this feature for better stability during overclocking, but it can be enabled for normal, non-overclocked usage to reduce interference.
Key Aspects of BIOS Spread Spectrum:
- Function: Reduces EMI to meet FCC regulations by spreading the clock signal energy over a wider range, rather than a single peak frequency.
- Recommendation:
Disabled for overclockers, as it can cause instability and slight clock variations - Impact: If left enabled, it generally does not impact performance in daily, stock-speed, non-overclocked use.
- Settings Locations:
- Gigabyte: BIOS -> Advanced Mode -> Tweaker.
- ASUS: BIOS -> Advanced Mode -> AI Tweaker.
- MSI: BIOS -> OC -> Advanced CPU Configuration.
When to Adjust:
- Disable: If you are overclocking, benchmarking, or experiencing random, inexplicable system instabilities.
- Enable/Auto: If you are not overclocking and want to ensure minimal electronic interference with other devices (e.g., radios, TVs).

Ok, i did the whole mobo removal and been spending 3 hours (and a tad bit more between remove/add mobo/cables) this afternoon to make a couple of vids. I can make a 3rd one if ya guys wanted about a topic i'll write below
Please note that the tower's cables related to the front panel (Lights, fan PCBs, both on the same cable, along the USB 3.2) has been removed to discard things out. The tower's front remains dimmed down hard with the power button barely lighted up
Here's the main vids:
Chipset focus. No GPU nor SSD cable (Else it goes into W10 and Fan Control lowers it down to 1300RPM, aka going natural in this vid). Only ONE CPU cooler's cable (RAM one) has been plugged in besides the CPU and 24pin ones
0:41 should make the "Riiing riiiing" electrical noise. Make sure to rise the volume hard
GPU PCIE Slot 2 (SSD and DP cables connected)
Ok, here's what i've found out
1. If i hear the chipset fan doing the ringing then stop it with the finger it stops, altho the head has a temporal recording of the noise that resumes like 3 secs later. It kinda seems the same if i stop the CPU fan. If i stop both well, the head recording plays out (Blame my sensitive ears and the frigging tinnitus). The PSU seemed to "share" the ringing but way more fainter (Had to lay down on the ground...) unless it came from the chipset/mobo itself from the distance (This is the "hard to pinpoint" part)
2.I then added the tower's rear fan to the CHA_FAN1 (Left side of CPU and rear I/O area). It SLIGHTLY increased the ringing noise but also slightly added to the buzzing around the VRM area. I was like "Fan speed or just the connectors are increasing tension within the mobo"
3. I inserted the GPU ONLY (No SSD) and of course clicked in the PSU cable into it. It sliiiightly buzzed a bit and the RGB stayed on all the time (BIOS/"No SSD" detected situation). The VRM area did some buzzings too (Seen on the vid above). Tried it in both PCIE slots. The ringing increased some more along adding that "Silent sound but ear feels it's intensity" feeling (Now that hurts a tad bit to hear...It masks a tinnitus on my left ear get masked out but this feeling makes the left ear to have a high frequency "Beeeeeeeeeee" wich's WORSE.
4.(This is the "If ya want a 3rd video" part). After spending 2 hours kneeling down i thought "Let's wrap this up". Placed everything back in place and thought "Let's put the CPU fans into a better position", wich kinda reduced some blade hitting noise (Hopefully because i'm tired of it) and then connected the CPU cooler's VRAM fan to the CPU_OPT header (BOTH fans connected now). Now here comes the fun. When turned on and hearing the mobo's lil speaker's "Beep!" the GPU buzzed a LOT everywhere but the fact is that the VRM area buzzed LOUDER (The worst buzzing i've ever heard in my history) and it SYNC'D with the GPU's noises!!!
My thoughts would be that:
1. Since installing the CPU cooler, be it when it comes to hitting the mobo around or something else, it affected the motherboard somehow and it's making buzz like crazy
2. The CPU cooler fan's cables (the black holder thing), even if cleaned with air dust and then blew it into the 4 pins in the motherboard, has made some back contact (Needs a proper cleaning?...But with wich tools?)
3. Maybe cleaning the chipset area+fan without the finger back then was a bad idea (It is bad but too late for that now) and affected the area even worse (Altho below the fan there's just... A black fan holder. Nothing motherboard, just a few tiny motherboard spots but it shouldn't be that bad, right?
4. The GPU adds more to the problem. A thing i forgot to mention is that there was a time i layed down the tower and the HDMI/DP cables were connected to the GPU and due to the DP cable's lenght it "pulled up" the GPU's DP port. The GPU was still screwed tightly into place , wich didn't "ejected it out from the PCIE slot", but the cable might've hurted the port some, wich could also be a reason of that "Silent sound but ear feels it's intensity" but i dunno if that's the case or the main culprit for the whole thing
You can see the DP ports here, with the left one's "top center" split in half some while the others aren't (HDMI should remain intact because it's a frigging 5M cable to the TV and there was no pull risk)
But what do you guys think?.Think the culprit's the motherboard or...?

1. Perhaps. only sure-fire test is to try a new board.
2. Nothing to do with cleaning fan headers.
3. Not sure I understand what you mean or how this would damage anything beyond the fan bearing, and even then unlikely unless excessive force were used.
4. Perhaps, but then this would mean swapping to the old GPU would resolve it. You can always inspect the port and pcb.
As to the audio, it won't be what you want to hear, but I heard nothing unusual.
Given the chain of audio processing/encoding/compression, plus YouTube processing on top I wasn't expecting to anyway.
Something to consider.
If you have reduced fan number/installed quieter fans and left the side panels off, you may simply be hearing pre-existing electrical noise that was always present but was previously muffled and masked by competing ambient noise.
I suspect you might not be happy until you switch out your board.
Maybe a different sound profile will be less irritating/perceptible to your ear as it seemed to be with your old GPU.

Given the chain of audio processing/encoding/compression, plus YouTube processing on top I wasn't expecting to anyway.
Something to consider.
If you have reduced fan number/installed quieter fans and left the side panels off, you may simply be hearing pre-existing electrical noise that was always present but was previously muffled and masked by competing ambient noise.
I suspect you might not be happy until you switch out your board.
Maybe a different sound profile will be less irritating/perceptible to your ear as it seemed to be with your old GPU.

Today i've swapped AGAIN my 2 front fans (Be Quiet! SILENT WINGS 4 High Speed PWM (1900RPM)) to Noctua's NF-A14x25 G2 CB Sx2 PP (1500RPM, 25-50RPM offset on one fan. 2nd bought set with the 1st one returned to to "I hear the fan hitting from my sitting position or even close up").
After a few secs of being powered on they seemed to work fine but i heard a new humming sound like a pig squealing or something. Hard to explain, along a slightly higher pitch ringing in my ear, masking one of my left ear's tinnitus noises. Returned to the previous fans and such noise and pitching is still there but kinda lowered (Planning on returning the Noctuas and YES, i tried them with both the tower's PCB PWM fan header and then the motherboard with the included Y splitter and cable extender to see if the motherboard could cause a different reaction, even the VRM area, but to no avail)
Now i must handle the front fans and the rear one to remove a "rattling" effect (Like if the blade's touching anything but it might be motor related... That, or the grill holder IS SH---- *SHOT!!!!*) by probably replacing them with a new unit of the same model. Altho last time i tried that with one fan at the front (AKA a new one and the prebuilt one) a "WOOO WOOO WOO WOOO" noise was heard like "That's not normal" in a "They're both running at the same speed with both fans touching each other
As for the pitching, if i set the BQ fans (From the tower) from level 3 to 1 this pitch noise, like a "Beeeeeeee(p)" is lowered down but still hear LVL 3's markings . If set to 3 then it goes higher of course. Sometimes takes a tiny bit to hear it. The fans (including when using the Noctuas) are using the included 10mm cylinder spacers to prevent turbulences (Wich have been working wonders till now i guess), altho maybe i am having some side effects from the Noctuas and it takes a few hours to get them off my ear, but if the pitch noise is back then something's wrong with the front area of the fans
This pitched noise is the first one here with the gray background but not that hard, more lowered and softer
This noise seems to be separated from the motherboard's ringing tho. I am starting to get PARANOID now, like once i discover the source of one thing then something else must come to prevent me to fix it and fix that something else. I don't know if the tower itself has something to do with this but THIS ISN'T NORMAL. IT'S JUST A FAN, NOT A HUGE ELECTRIC MOTHERBOARD !!!!
And i tried unplugging the tower's HD AUDIO and USB 3.2 header just to see if the motherboard was interfering with the tower somehow but nope, still there...
There's no ambient noise (like a TV, phone, console, etc). Only the fans and the ringing from the motherboard. The room's silent with some inner wall soundproof (Yet still some external noise can be heard)
In other words:
-The motherboard ringing, i don't know what's causing it. It happened with 2 PSUs after a long time and since the CPU cooler that this is happening and don't think a different branded PSU can make any change
-There's something wrong with the front fans that causes a more bothersome high pitched noise than the motherboard topic. They've been working for 2 years, sure, but even brand new Noctua fans have this issue and a bit worse
-Maybe the front fans' LVL 3 speed (1200RPM) is causing the chipset fan to speed up, making it's ringing speed up too and make some after sounds or something, but i could be wrong
-Or there must be a connection between the motherboard and the tower that i am not looking at correctly. The tower only has one SATA powered cable connected to it wich's the I/O front panel. If disconnected it's lights turns off except the power button wich just dims 50%. Could it be related?
I asked BQ to send me a couple of mini PCB fan headers to replace the tower ones (along long screws for the fans). A month n some ago i asked for a new front I/O (the tactile buttons etc) and i only changed the PCB for the front panel with the replacement, not changing the cables' one. Dont think it made much difference tho
Any thoughts?. Sure i could lower the front fans to the minimum but the tower must be COOLED DOWN...

Ok, i did a 2nd discard testing in a plug/unplug way.
Motherboard placed in the tower. ONE CPU fan (RAM one) in CPU_FAN header, rear fan in CHA_FAN 1 (Left of CPU), tower's front fans in their own PCB BUT their power cable was unplugged (Easy to reach). USB 3.2 connected along HD AUDIO
All rear ports minus the internet cable and mouse were disconnected. Everything was silent minus some noises carried from work. PSU was dead silent
Steps:
1. Power on the PC. Go to Fan Control and put all fans (CPU, rear, chipset fan) to OFF (Temps were kinda stable, wich chipset to 75C, CPU around 48C). Disconnected the front fans' hub from PCB's power
2. A tad bit of "silent but intense feeling" was felt around the VRM area but unsure if it came from the PSU instead (They're close to each other so it's hard to tell)
3. Connect the speakers (USB C port, no adapters). It tinyly increased the ringing noise to the most minimal. PSU seemed to resonate in the same level (Could be the reverse this time, with PSU maybe not doing it but it's the motherboard)
4. Disconnected it. Back to silence
5. Started the rear fan. It seemed to increase a tad bit of the noise and intensity. Disconnected. Silence
6. Activate the front fans on LVL 3. The "Rii iiiing" noise along a "Weee weee weee weee" wave was coming from them if placing the left ear there along an increase of the "silent but intense feeling" thing. Remember that the only things connected to the motherboard with the tower are the HD AUDIO and USB 3.2. Not sure if disconnecting them could make it vanish the noise (Gotta try later). Placed the fans to LVL 1, they lowered down both noises
7. Disconnect the front fans' HUB. Start the CPU. Almost no noise (Some leftovers in the left ear)
And remember that the front fans have a 10mm spacer so that there's no turbulences, not even, maybe, "The fans sucking air through the chassis' holders, creating some -whistles-" (the "Wee wee" noise)
So most part of the noises might be coming from the front fans (Or it's PCB?) and part of the rear one. However, like i've mentioned, using the Noctua fans at the front created a similar situation with an added wave noise to the mix (the "pig" one). Also included in the mix would be the sound of the blades spinning like if they were hitting something (This is a noise that temporally gets stucked in the ears too), so not sure if the Noctua's "being new" could make some kind of difference or if the issue comes from somewhere else. Maybe it's because the fans are together and are creating this weird noise?
Could the front fans' PCB might be damaged?. The only thing weird about it is that one of the 3 ports there's plastic that holds the fans is curved upwards to the PCB but not touching the PCB. Could it be related?
Or would something from the front I/O, even tho it was never opened before all this happened, have something to do with the PSU?. Or that my ear became more sensitive as for late but this ain't normal. Dunno if it could be that back then i used an air dust can to the fans or a hair drier on cold and making the fans spin while the PC was powered off could be the reason of a bearing making electrical buzzings or something. The intensity comes from the I/O area from the front panel but dunno why
But then... How come if even after disconnecting everything from the PC and putting the motherboard outside on cardbox i'd hear that noise then?...Please tell me it's not the PSU, because if i change to another brand and the noise persists then there's gotta be another reason

(Can't edit, sorry)
Tooked the PSU out, connected all the components to it. Such noises doesn't seems to come from it (Unless, again, the distance is trolling me or something)
I placed it back in, kneeled sideways so my left ear aims to the front fans, then started putting the finger into each one. Seems like the front's top fan, rear fan and chipset fan are there culprits (Altho for some reason my left ear doesn't hears the chipset fan from behind the motherboard). Front fans and rear one at 1200RPM while the chipset goes natural between 1700-2200RPM
I don't think inserting the Noctuas once again could solve the problem if that means adding a new type of noise in the mix that could make things worse... And not sure if the fans now are doing the same kind of Noctua's noise now. And i don't know why the front's top and rear fans would do this waving noise if they're tightly screwed so there's no resonance, etc, and don't think i've screwed em badly or bent the tower's chassis out
Nor i understand how the front fans can cause that silent yet intense feeling on my left ear when the tower's at my right side. Changing speeds from the front panel's I/O seems to do it but i think even connecting the fans to the motherboard via Noctua's splitter+extender (From the Sx2 PP pack that i am still having...) keeps this intensity issue to happen
Is there something else i should try out or just WTH's going on with the PC?... Sure my left ear is hella more sensitive than the right one, but COME-ON !

It could be your case doing it and resonating at its natural frequency from things inside the case like fans and other devices resonating.
Resonating at its natural frequency occurs when an external, periodic force matches the frequency at which a system naturally vibrates, causing maximum energy transfer and drastically increasing the amplitude of oscillations. This phenomenon, found in mechanical, acoustic, and electrical systems, allows small, repeated inputs to produce large-scale vibrations or, in some cases, structural failure.
Key Aspects of Resonance
- Definition: Resonance happens when the frequency of an external driving force equals the natural, or resonant, frequency of an object.
- Amplitude Increase: As the driving frequency approaches the natural frequency, the system absorbs more energy, leading to higher intensity, large-amplitude vibrations.
- Energy Transfer: Resonance is a highly efficient method of transferring energy into a system.
- Damping: If damping (friction) is minimal, the resonance frequency is approximately equal to, but slightly above, the system's natural frequency.
- Musical Instruments: A string on a guitar vibrates at its natural frequency when plucked.
- Acoustic Resonance: A tuning fork can cause another to vibrate if they share the same natural frequency.
- Engineering: Resonance can cause catastrophic failure in structures like bridges or aircraft wings, but is also used for utility in electronic tuning circuits.
- Everyday Life: Pushing a child on a swing at the right time (matching its natural frequency) makes it go higher.
- Frequency Adjustment: The natural frequency can be altered by changing the mass or stiffness of a system (e.g., adding water to a glass).
- Damping/Isolation: Vibration dampers or isolators can be used to prevent resonance from spreading in machinery.
But wich parts of the case could be the resonating culprit tho?. My only suspects would be the wind going through the holes from the front fans' holders (the screws part) along the rear fan's holes (Honey bee/comb/whatever holed part of the chasis)
Could the front fans' placement being together be a possible culprit?. Should i separate them some?
Need photos of specific parts of the tower (Front, inside, side(s), rear, etc)?
