Hi all. So I just recently got a new case, motherboard and AIO unit.
After putting everything back together, everything is working as expected, however I am hearing a sort of "buzzing" noise in the case only while a game is focused. The noise isn't present outside of games or even when I'm tabbed away from the game. In the video I have Baldurs Gate 3 open and I am tabbing to and from the game, and you can hear the buzzing when the game is focused. I heard it with Starfield opened also.
I don't think it's my fans because I ran them at full speed as a test and didn't notice the noise. The noise sounds near the AIO unit or maybe the GPU. I transferred the GPU from my old mobo and I didn't notice the noise before - however my old build had much louder fans so there is a chance I just didn't notice it as much.
Its not extremely loud but it's just loud enough to notice and be kinda annoying.
I asked the clankers what it might be, and they pointed to maybe coil whine from the inductors on my GPU or some other electrical interference, but I wanted to just see if it were something simpler or if there was a simple fix.
Any advice would be much appreciated!!
