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

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?

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 =/

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...?

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.
