And of course, make sure the vents are clear too.
Are you overclocking it by any chance? That could be working against you too.
It's been over-clocked in the past, but not now. The fans are all working, and I've tried running it with the side panel off (I'm trying to pull data off the drives). I've ordered some thermal grease with the components for Quadcore machine, so I can trying cleaning the P4 and reattaching the heat sink/fan.
