I finished a build about a month ago that's been nothing but a nightmare, don't even know where to start. I was having EMI issues, then found out there was coil whine also. The coil whine is my main concern at the moment. It is almost constant, and fluctuates when I move my mouse regardless of what I'm doing.
I've RMA'd both the PSU and motherboard at this point. Just put in the replacement board today and the coil whine is worse. Every time I've tested without the GPU installed, so that's not the issue. I've tried different outlets throughout the house. I've tried my old PC on the same outlets and with the same mouse and no coil whine there. It sounds like it's coming from the RAM/CPUish area.
I've wondered if it's one of the PWM fans on the front of the case or on the CPU cooler, or maybe something with the front panel cables of the case but I have no idea. Can the CPU itself cause coil whine? RAM?
I feel defeated, please save me lol. Haven't been this discouraged with PC building before. At this point I'm thinking about spending the money I saved for a monitor and just buying a different board, case, and a couple fans.
Specs:
i7-8700K
Scythe Mugen 5 rev. b cooler
16 gb 3200 g.skill ram
MSI RTX 2080
ASRock z370 Extreme4 (cursed mobo)
