Ever since I built my first PC about a year ago, the CPU block on my H100i Pro has made an annoying sort of grinding sound (https://streamable.com/0prdc) since I've installed it. This being my first PC, I assumed it may have been normal. It doesn't effect cooling at all and it's performing well, however now it's starting to bother me more. It's the most noise the machine makes and is very audible over the system and GPU fans. Does anyone know what the issue may be and how to solve it? I'd at least like some peace of mind to know what's going on. Thanks in advance!
