Anyone identify this noise?

Cheeky_Chris · Jan 24, 2014

It isn't any fans as they are all new. Distinctly coming from the CPU area of the motherboard, but I have no idea what it is. Really irritating as I want a silent PC :/

Sounds like a hard drive spinning. Other than fans inside a Pc the only thing spinning is the HDD.

+1 to that. There is not much you can do to fix that, other than...

1) Defrag the drive
2) Delete programs that you don't really need
3) Buy a new drive and put about half of the programs onto the new drive, or
4) Buy an SSD, and just put the OS, and your most frequently used programs on it.

Jacob McIntosh :

Definitely not the drive. I have tested the system just running on my SSD with the drive unplugged and upon listening to the mobo backplate it is definitely around the CPU/RAM area

Jacob McIntosh · Jan 24, 2014

Are you using a watercooling setup in this PC?

Then it has to be a fan , try disconnecting one fan at a time to see if the noise disappears.

Jacob McIntosh :

No. Funnily enough when I was using a H100i I thought it was the pump so I returned it. To my horror it's obviously something deeper. The only this I can think of is that it's coming from the CPU or motherboard

Already tried. Besides, the 4 Noctua fans I have in my case are brand new and I just got them today. The noise was also present even when I just had the stock fans installed

Jacob McIntosh · Jan 24, 2014

The only way that it could be coming from the mobo is if it has a fan built in, otherwise it is a system fan somewhere. Most likely the rear exhaust fan, unplug that and see if it is better.

By chance could it be a PSU fan?

Jacob McIntosh · Jan 24, 2014

Unless you have a top mounted PSU, probably not.

BluePhantom · Jan 24, 2014

Jacob McIntosh :

I agree, however i can't see for sure given the video so its worth a check.

inzone · Jan 24, 2014

The only other thing I can think of is a bad Cap on the motherboard or a coil whine in the PSU. With digital components there isn't much that can make a noise. Certainly a CPU cannot make noise and Ram cannot either.

Cheeky_Chris · Jan 24, 2014

BluePhantom :

The PSU is a Corsair RM 750, bottom mounted in a define r4. As. I say the noise is definitely in the CPU/RAM area. Will delve more deeply into the PSU tomorrow, otherwise I may have to return the i7 and z87 Sabertooth and see if new ones fix the problem

Cheeky_Chris · Jan 24, 2014

inzone :

I was thinking mobo coil whine. I will have to listen to the psu properly tomorrow and if not just rma the mobo, which'll mean taking my whole PC apart T_T Joy

BluePhantom · Jan 24, 2014

Yeah id be seriously thinking it was something with the PSU if you already checked the fans and HDD. Be sure to let us know what you find out

Cheeky_Chris · Jan 24, 2014

BluePhantom :

I will. Not having many good experiences with my first ever build so far... :S

BluePhantom · Jan 24, 2014

Cheeky_Chris :

Don't let these kind of things ruin the experience, it happens to the best of us! Best of luck!!

Cheeky_Chris · Jan 25, 2014

BluePhantom :

Turns out it was those tiny fans that come on the sabertooth, I unplugged both of them and my PC is now totally silent :lol:

Cheeky_Chris :

If you want to put new fans in place of the ones you took out, I found a few options...

Sort of shows the quality of the Noctuas! I couldn't hear 3 140mm fans or the 1 92mm fan but I could hear the 10mm fans!
