First thing, I am not sure if its the same sound, I do sense a very distant kind of coil whine, so guess thats just standard when using power. the clicking sound have not occured yet.
Another thing that poped into my eyes is the "packets" under CPU Powers in my HWmonitor.
Before when i ran prime etc it sometimes reached 90w now it only goes to 56-57w - So ofcourse i check that out and according to intels side the cpu can only draw out 77w - Is it possible that the PSU have just pumped in more watt than the cpu can actually handle? or is this watt solely controlled by the cpu?Atleast it is "1 thing fixed".
Cant say more for now, gotta have it running for longer and play some more games to see if that special sound comes back, gonna be a bit harder to hear, as this XFX PRO650w xxx edition always have fan running!
