    My friend has a macbook and when his gets above 150 (or there abouts) his fan turns on to a higher speed. now when my cpu gets hot like 150-160 the fan still stays at idle of the low setting and wont kick into high speed, any reason for that?

    thx

    150F is still normal temperature for todays CPUs when they are under load. When you start hitting 200F, you may have a problem.

    To manually change fan speeds, download SmcFanControl

    How long are you waiting? You're not at 200° F either.
