The fan on the north bridge chipset of me abit KT7-RAID is fluctuating, like speeding up and slowing down. It is very annoying. I know they that the fan is not necessary but I kinda want to keep it on. Is there a way to replace it? I took it off and cleaned it with a Qtip and put a little WD-40 on it. It seems to be working but every now and then it will do it. Basically is there a replacement fan I could get for it besides the one Abit makes? Also has anyone else had this problem?
