High Pitched Noise

CurlySturly · 2 Sep 2016 at 22:36

So, just built up my PC without a GPU (due to having to wait for my next paycheck...). But since I put my fan on my CPU cooler (Raijentek Eveboss) I've started to hear a high pitched noise, even with the side panel attached.

Does anybody have any idea what it could be? All components bar a GPU are installed so instantly I thought it was my CPU cooler fan due to only having put it on after I first booted it all up.

Thank you in advance.

May be coil whine from you're graphics card

I would try just stopping each fan to see if it's one of those, but may be the PSU so just need to be careful there

Check all power connections are firmly made. If using a modular PSU check leads are properly connected at PSU end too.

neat ... in a system without a graphics card.

As said, check power leads, check cpu cooler hasn't been over / under tightened. Did you run the system with a different cooler and had no issue ?

Does the noise change when the CPU is put under load?

The noise wasn't there when I didn't have the fan attached to the CPU cooler and my system at idle for an hour was running at 21 Degrees Celsius. I played mirrors edge and it didn't push the Tempsford up any higher than 31 degrees C. Then I did the exact same thing with the cpu cooler fan on and it was the same temps but with the noise.

I'll check the power connections when I get home. I have a feeling the CPU fan lead might not be tight in thinking about it

check the cpu socket pins too if you can bent misaligned pins can cause a screeching sound

Here's a very simple check for you: when it's making the noise, try stopping the fan with your finger. If the noise stops, you've found the source of the problem.

This, probably crappy bearings on the fan or you over tightened the fan when fixing to the heat sink... Some fans will make a noise in different orientations so stop the fan, if its gone its the fan.

Well the good news is that when I did this the noise stopped so I guess it's that. The mounting brakcet is really weird for the fan as it's 4 metal wires that run from the fan and go along the body of the cooler to the back and attach to the fins.

I'm just wondering if I'd be able to run the system in a passive cooling capability though, thus taking the fan out of the system?

I have a 140mm intake fan which blows in a lot of clean air into the case with exhausts on two sides of the cooler So II'm wondering that would work?

So either the fan itself is noisy or being held against the heatsink is making something inside squeak. Try pulling it away slightly. Failing that, try replacing it.

It would certainly work but might run pretty warm.

It looks like the fan is attached by noise dampening rubber grommets, I think you can use another 120mm fan just pass the rubber through where the screws would go. At least thats what it looks like...

They are like this right?

If so grab these longer ones and chuck on a better 120mm fan, seems like the bearings are crap in the one supplied. You could get another slim fan but if you already have one spare a few quid on these might do it.

Any chance you could post a picture of the cooler with the fan attached?

Sounds like it is fitted with the wrong type of mounts.

You did mean you have this cooler?

An answer to your questions!:
-Smffy: those are in fact the mounts but in the instructions to the cooler it suggested using the wires as well so I did that as well to make sure the fan is extra thight to the cooler (so it won't fall off).
-freddie64: it is that cooler yes. how the fan is attached is different though compared to how they say in the manual!

I think I've mounted the wrong mounts as you've said as any product picture I've seen show that it's only those rubber mounts, not the metal wires...
I'll post a picture now in a separate comment

I've just created this account so it's the only 2 pictures in that profile

I had his problem with one my fans! Was an awful sound.
What I did was unplug the fan and reconnected it and it stopped.

For me it's looking more and more like it's the actual fan being the problem as done of the mounts slot in properly either. Just as well really because I was looking to upgrading to watercooling when I buy my GPU anyway

Smffy · 4 Sep 2016 at 14:29

Plug the fan in off the cooler, hold it in your hand an turn it different orientations. Quite often its one direction which is causing the noise in the bearings but try mounting with only the grommets.

Failing that try another fan.

Could be the wife in the back ground complaining you don't listen anymore?
