I have a nzxt phantom and the side 120mm fans keep stopping for a second so the fans slow down and then they speed up again.( This is when they are on full speed) Its only them two fans that have the problem all the other fans in the case are fine. I was just wondering whats going on. Also some times when I turn my pc on the fan at the top doesn't work but then after a few seconds it starts up?
