The old fan on my Athlon 900 slot processor just went bad, and now the fan on my 8KHA+ just started making weird noises. It spins slow, then speeds up again constantly, making loud a loud noise. I have to tap it with a pen to get it to quiet down. The computer is on 24/7. And I keep the inside of the case very clean (I only have two cleanliness settings, either crazilly clean, or half full diet coke cans and garbage everywhere). What can cause fans to stop working?
