    My wife's aluminium MacBook bought six months ago has run cool until the last few days. Now when she leaves the machine alone and the screen saver comes on, the fan cranks up to 3800-4800 rpm. The screen saver hasn't changed, nor has anything else with the exception of the recent software updates. Does anyone know if the new Safari update (or the iLife updates) could cause this type of problem?

    Also look for hanging processes in the Activity Monitor...print spools are a common culprit.

    I know how to reset PRAM, but how about SMC (I honestly don't even know what that is!).

    If it's not in the knowledge base then worry.

    NewMacbookPlz brings up a good point as well. I'd run Activity Monitor and see what happens.
