Recently ive been hearing a high pitch noiise coming from my pc. After playing games or doing another resource intenaive task, it begins. Ive tried turning off amd quietncool tech (powernow) and c6 mode and nothing helps. I was thinking that i could be the psu, but when i had it in my other pc it was fine. Im thinking since this is a smaller case, the hdds or something could be having a problem with heat.

My specs;

2hdds
Amd a8 3.2ghz quad core
8gb ddr3. pny ram slot one is 4gb 1600mhz and slot 2 is 4gb 1337mhz
550 watt psu and some asus tower and motherboard
The model number is cm1745

I apologiae for my spelling mistakes and lavk of grammer usage, as i am on my phone right now.
