Something is seriously wrong with my MacBook 2.0 C2D. Lately, the fans run at around 6000 rmp all the time. I've checked Activity Monitor constantly and everything seems to be normal, i.e. there is not a printer file or anything like that making the fan run. I also reset the PRAM and still no dice. I am running Leopard and have maxed out the memory to 2.0GB. I have had this computer since August 2006. Can someone please point me in the right direction?
