    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?

    Try resetting the SMC and PRAM first before needlessly cracking the machine open.

    I doubt replacing the thermal paste will make any difference in that machine, it's most likely down to Lion - it makes the fans run quicker on my similar machine than Snow Leopard.

    you CAN change the paste put it likely won't help much. I changed mine, my temperatures are generally the same under load and 5-8˚C cooler idle.

    Now although the temp isn't cooler, i can tell the new thermal paste works, the heat sink temperature changes a lot more than it did before, so it's more in sync with the temp fluctuations in the cpu. but yeah, not much cooler, maybe 2-3C cooler, if at all.
