I am having fan problems. My case fans normally run at 1200 rpm but every other second, it'll read 675,000 rpm. Obviously the fan itself doesn't spin up to 675k rpm but it's quite annoying. I don't think its the fan because I tried changing around the location of the fan connection but using the same header. Please help. It's a brand new system and I updated all the drivers already. BTW, the headers doing this are for the case. CPU fan header is fine.
