I just built my new PC, and I hear a high-pitched whine sound, almost dog whistle-like, that occurs every 8 seconds for about another 8 seconds, and I have no idea why. It's really starting to bother me if I do not have headphones on. I honestly thought I got good enough parts that I wouldn't have to worry about a loud PC, but honestly, even with fans set to silent in BIOS, my PC seems pretty noisy on idle. My temps seem to be great. I feel like it might be the AIO, but I've heard nothing but good things about Arctic Liquid Freezer III, and it seems like a real pain to replace or fix. Any recommendations on fixing this whining sound and/or noise levels are appreciated! See Specs below.
