I have the A5600k for two weeks now and the procesor is working ok but,there is a very high pitched noise coming out from the cpu area.The noise changes when i do any operations such as moving mouse opening closing windows.Even if i press some key on keyboard it reacts.I can alo hear it in my headset.I have Asrock A75Pro4-M motherboard and 8 gigs of ram running on 1600.All the components are brand new i even bought new PSU.but the sound is still there.

I really need help with this....

Sounds like coil whine to me.

coil whine is the result of one of a few things, or combination of.


Power Supply is putting out crappy power, and the motherboard voltage filtering is working overtime trying to smooth it out, this is the usual suspect, or the capacitors and coils on the motherboard are of sub-par quality, and just emit the noise. I've never liked ASRock, so I would suspect the 2nd option very likely.

I had a very similar problem, and I run an A8-5600k.

I swapped the stock cooler for a GeminII S524, the fan speed was controlled by the board.

I noticed when I first started the PC up, there was a faint whine coming from the CPU area. I then disabled the RPM control for the fan so it stays constant. That noise is gone.

Try it yourself.
