Reduce Coil Whine Today!

Why can't something be done in manufacturing to mitigate or stop this entirely? When this first started to occur on cards a good few years back some manufacturers were encasing the components in a glue type substance and others in a type of plastic to stop the noise, now it just seems they don't bother and it's a crap shoot if you get a card that does it or not.

Used to be you could also rma due to this, but now it's such a common issue the card would have to be smashing glass with it's pitch to get it replaced.

I had one of OcUK's super-special GTX 970s with the coils glued or whatever it was they were advertising. It still whined (or rather buzzed, as is much more common in my experienced). Buildzoid actually did a video about the cause of coil whine that's fairly interesting:


The TL;DW is that modern cards tend to have more coil whine because the types of inductors that are most prone to causing it are also the ones with the best physical and electrical properties. You can get ones that rarely suffer from it at all, but they're larger and can't handle as much current, so they rarely get used any more. GPUs are also just inherently prone to causing coil whine due to the way that they work electrically.

I think also the fact is that the faster the GPUs are, the more prone they are to whine due to the sheer volume of FPS they put out, that ties in with what Aretak says about about the current drawn.

You don't see too many reports of coil whine on the lower end GPUs.
 
I heard that it also is worse cause GPUs now run around 2Ghz whereas back in '12 they were around 1Ghz.

I am not sure mechanically how running the coils at maximum whine causes them to create less whine. But I haven't tested it myself, my cure for coil whine was to move the PC away.
 
This is historically how you can get rid of coilwhine, i had a bad 680 once and left it running heaven benchmark for an hour or so really did dampen the side to the point it eventually went away.
 
Don’t know why you are getting some salty replies, I thought it was common knowledge that coil whine can often reduce as the inductors are used... evidently not that common.

I’ve had it several times where a new card has some slightly annoying whine which then for all intents and purposes disappears over the course of a week or two of use as the inductors “bed in” and the frequency moves out of the resonant zone.
 
I’ve noticed on some older games where there is a level transition or menu the frame rate goes through the roof even with a frame rate cap. Gta4 on mine gets over 5000fps squeals like a pig for a short time ahem :D

Coil whine pah. What's a matter with you lot. I used to run a delta cooler on an old athlon, now that was noise.

Same here, that was when i was younger and had more tolerance for the noise :p. Still remember putting that "core cracker" cooler on and cacking myself incase i damaged the cpu. Can't even remember the name of that cooler but you had to use a screwdriver on one side of the clip to put it on.
 
Luckily the 3080 that I have has 0 coil whine, however my old 2080ti Strix did have some under high fps. I bought a new Board today and the VRM has some crazy coil whine, I didnt even think that was a thing lol
 
I've got very bad coil whine coming from either the 3090 or the PSU.

Just ran Night raid and managed to get an almost buzzing sound out of the 3090 which is different to the noise I'm hearing constantly which is a high pitched almost metalic sound, and its there whether I'm at the desktop or playing games.

Do the custom run and set it up on loop and leave it running for 24 hours or at least overnight. See if it helps.

that video got errors in its. The sound these inductors give out isn’t based on FPS. It is based on the switching frequency of the power electronics. The modern pc components have variable voltage and current delivery system which means the switching frequency changes in accordance with demand. Those switching frequencies are probably in the kilo Hz if not 100s Kilo Hz on GPUs.

I built my first ever AC-DC variable voltage controller and a DC-DC variable power control circuit in my uni and I noticed the noise and they have a resonance where certain switching frequency it would be very audible and then gets quieter either side of that resonance

the same stuff is happening in substations - the constant hum you hear when you go pass a substation. But that sound is a constant note because those are switching at a constant frequency.

Edit: also rewatched his video again, it seems he was inferring that the magnetic field generated by these components somehow cause interferences to one and other and cause “plates” to move and oscillate. That’s not the case. The fields generated are small. If they are large enough to move things then you are in trouble as it will all sorts of issues in the PC. The noise is from the core being energised each time it is being switched on.

I am not a fan of buildzoid stuff. I don’t know what his background is or expertise is. But a lot of it is speculation and hearsay. He knows his RS component catalogue for sure.

Unfortunately hasn't resolved anything for mine after a night run last night which was painful since it in my bedroom lol. Can't even RMA as not being accepted as has had a waterblock on it so stuck with it now. Tempted to offload and get a 3080/3090 it so bad.

I mean in a stock system in a proper case with panels and it under the desk etc it probably wouldn't be so bad. However this is head height pretty much about 18" from me and right at the front of the build so no way to dampen the sound.

Lol, ouch not great if you have to sleep in the same room.

Run it again, keep running it. It will get better, at least in other games/apps. :)
