Just finished my new gaming rig. Lovely machine, all works a treat. However I do have one question and a potential problem.
The CPU makes a buzz. A little like an HDD trying to read the disk. Like electrical static. It's coming from behind the pump for the H90 (or could be the pump itself? I doubt it?) So it's either the CPU or maybe a transistor located near the CPU.
I'm not sure if this is bad, or normal, or if I should just leave it alone. I never noticed the noise before I started my tame OCing. I'm completely new to OCing, I've never done it before but after several articles and a few videos, I bumped the CPU up to 4.4ghz. I went higher eventually to 4.6ghz but was unhappy pushing 1.3V through the CPU so lowered it back to 1.2V and 4.4ghz. When I discovered the noise I had done my first overclock and was unsure as to whether it was there before. I have reset the BIOS settings back to stock and the noise is still there.
I hope there is nothing wrong and this is quite normal. You cant hear it with the case together unless you put your ear up to one of the grills. So you get an idea of dB. :)
