I have a case of Jet motors vibrating the entire apartment complex. The fans are very silent during bootup, but as soon as I come into Windows, the fans start going extremely apeshit. I honestly thought that my PC was going to catch fire first time I heard it.

I've recorded and uploaded an audio file demonstrating the problem i'm wrestling with:

PC is very new; built it yesterday.

CPU - i3 6100
CPU-cooler i3 6100 stock cooler
GPU: ASUS GeForce GTX 1060 3GB Dual OC
Case: Bitfenix Nova
Motherboard: Asus H110M-A/M.2
RAM: 2x4GB DDR4
HDD: WD Blue 1TB 7200rpm
PSU: Corsair CX650M


Also, I'm not sure whether the sound is coming from the GPU or the CPU-cooler. I've also tried adjusting fan speeds through BIOS & various softwares to no avail.

Whoever helps me solve this problem is a total legend.

When I say CPU fan, I am referring to the cooler. The cooling method of the cooler is primarily a fan with heatsinks. You can still control the curves of your cooler. Stock coolers can be a little loud at full rpm, but I dont think it should be as bad as you seem to think it is. Are you sure the cooler is seated properly and not vibrating?

I use one 120mm fan that comes with the case.


In the 4-pin CHA-FAN. The case fan I'm using has 3 pins.


I use Asus AI Suite 3. It was like this even before I used any software.

Ok as long as your CPU cooler is connected to cpu_fan and your case fan is connected to the 4 pin ch-_fan header then thats the best you can do.

Did you set two different fan curves for your cpu and case fans? And do the curves actually make any difference to the RPM of either one? Dont forget the case fan responds to system temps, not CPU temps.

It could be that using the 3 pin system fan in the 4 pin header means it runs at frull speed at all times, or the fact that you have a 3 pin and a 4 pin connected are conflicting with one another.

Check to see if you are controlling either fan, or if the RPM stays the same no matter what the temps are.

It's not the fan that is at fault (I started the PC without the case fan connected to the motherboard for deductive reasons). I'm very sure that it's the stock cpu-cooler that needs changing.

Your effort has been greatly appreciated though! Thanks.
