    i have a 2007 mbp (the one with the removable battery).

    i have kept it in great shape over the years and have always installed the latest updates etc... i even upgraded the ram from 2gigs to 4gigs and replaced my battery a few months back.

    the computer used to go hours on end without the fans on and without overheating...

    now i turn it on and 2 minutes later the thing is boiling hot and the fans are on full blast.

    is this thing dying? should i attempt to open it up and put new thermal paste on the processor? (if this is the answer... how the f do i open this laptop up safely?)

    dont know if this is related but the computer has been running extra slow recently as well... even with few applications open.

    any suggestions? is it time to get a new macbook? (not too excited about the prospect of throwing down $2500 on a new one... as I need a 15" screen, not 13")

    PRAM and SMC reset followed by some Activity Monitor and iStat Pro monitoring.

    The fans are always on when the MBP is on, at a minimum of 2000 rpm. They spin faster as needed to keep temps at a safe level.

    Install iStat Pro to get accurate readings of your temps, among other things.

    Your Mac is most likely not overheating. Macs are designed to automatically shut down to prevent damage if they truly overheat (around 100C/212F - 105C/221F, depending on your processor). Your temps are probably well within the normal operating range, as searching the forum with Google will reveal:

    On the fence
    Check activity monitor for an application that is hogging all of your resources. That is most likely what is causing it to get so hot and spin up the fans.
