[QUOTE="DrQuincy, post: 1584029, member: 22571"] Well, I did the hardware test from the Snow Leopard disk and it came up with a fan error on the hard disk. I restarted and a progress bar came up and it took about 15 mins to boot. I then did a PRAM reset and now I've been using it for four hours and it is totally silent! No fan overuse (it normally comes on about an hour after use) Does the hardware test actually fix anything? Could it have been the PRAM that caused the error? Or should I be worried about imminent failure of the fan? [/QUOTE]
