Noisy computer help?

Hello,

Lately my PC is emitting a lot of noise, usually when playing CS:GO or other games. Spec:

AMD Piledriver FX-8 Eight Core 8320 Black Edition
Gigabyte 990FXA-UD3 AMD 990FX
Corsair Builder Series CX 600w Modular
Samsung Green (MV-3V4G3D/US) 8GB
ATI Radeon 5770 1Gb
1x SSD 3x HDs
Antec 302 Three Hundred Two Ultimate Gaming Case

I believe the sound is coming from the fans although I don't know which ones, it is usually quieter after I turn case fans to Low. I have cleaned the inside of the case, there is no dust under any fan in the system. I can get stupidly loud and physically makes my desk vibrate.

I've run SpeedFan and under load the CPU does not go over 42 but the GPU can go up to 60 degrees.

How can I reduce noise? Would replacing my stock case fans help much? How much would upgrading the graphics card help?

Thanks
 
replacing the gpu would help,ive owned a 5770 and they are loud compared to my 7850

replacing case fans with pwm fans would help aswell,akasa apache fans are quiet
 
Bought two Akasa Apache fans, thanks for the recommendation. They do look quiet for the price.

Will be looking to upgrade graphics card to a nVidia 760 or similar soon.

Any other ideas?
 
Its probably your GPU making most of the noise. The vibration may be your HDDs seeing as you are running three. You can quieten them down by mounting them in the 5.25" bays either with special anti vibration mounts or with bungee cords. If you are running the stock cpu cooler it might also be worth upgrading it to a cheap but quiet cooler such as:
YOUR BASKET
1 x Raijintek Themis Direct Contact CPU Cooler £19.99
Total : £25.97 (includes shipping : £4.98).

 
I think it is the GPU making the most noise yeah

The vibration only happens when the fan is going full pelt

The CPU doesn't go over 42 degrees so I can't see the CPU fan having much to do


I put one of the Apache fans in and it's louder than the stock Antec 2speed cooler, it sounds very high pitched and is much more noticeable =/
 
did you connect the akasa to a four pin header? it should be quiet

try and support the gpu,stop it wobbling when fan is full speed?
 
GPU is probably main culprit, when you have the time I'd replace PSU as well you'd be surprised how loud some can be.
 
The akasa is connected to a 3 pin connector. The mother board has only 4 pin fan connecter which is out of reach at the bottom right of the board

The PSU is less than a year old and is a relatively good corsair one so shouldn't be a problem

The GPU is pretty securely in place

Does that fan sound normal in the video...?
 
its hard to tell,i have a 5770 and the fans are noisy

you can alter the mb fans speeds with voltage on gigabyte I think,in the bios,that should make the 3 pin headers/fans quieter

it would be very silent on the 4 pin header
 
So the akasa fans are running at full speed which explains why they're not near silent. You can grab a fan controller to control their speed which in turn will affect noise. Personally I have an akasa apache fan and it is very quiet even at full speed but on my side panel it vibrates although this is not the fan as all fans do it so noise is due to something else

As wazza said maybe you can control them through BIOS or software such as speedfan
 
I connected the akasa to the 4 pin and it wouldnt work, tried the 3 pin and it worked

Put it back on the 4 pin and it worked after I gave it a kick start with my finger. Bit odd.

Speedfan says it was working at 2500 rpm before and is now working at about 250. So its obviously quieter.

After "manually" stopping each fan in turn its clear the CPU fan is actually the loudest, more so than the GPU. More things to invest in I guess.
 
Not odd at all, apache fans don't like low voltages for some reason, I have one hooked up to a fan controller and it doesn't start if I have the knob turned all way down so I just leave of at half way. All fans have different starting voltages unfortunately so it's worth checking on future

Yes stock CPU coolers tend to be loud, thankfully there's lots of aftermarket options :) Apart from being quieter they also reduce CPU temps which in theory should extend life time of the CPU
