I must say, my coil whine is attributed is atrocious and unacceptable on my Unify-x. It even makes noises when moving the mouse.
Strangely, it’s at its quietest when benchmarking. Leaving it to itself is just a bit grim and very distracting.
I did break a screw as mentioned earlier but another person has described exactly the same thing without that ‘error’ / design flaw.
Disappointing but hohum.
I did the screw tightening thing but didn't push it at all, only the slack. Didn't notice any difference. Im going to try with a game today to test.
What will you do? Wonder if it's the psu interaction? Try another board?
