Hi, i have the Macbook 13" Aluminun late 2008 model. I upgraded to Lion, put a new hd (Seagate Momentus 500 GB hybrid) and bumped up my ram to 8 GB. But i always had the fans kicking in and it's very irritating, i want to change the thermal paste. Here's my temp running right now (having open around 20 tabs on Safari) Is there a guide to follow so i don't screw it up? Thanks!
