    Hey I would just like to know if these temperatures are acceptable. They just seem a little high to my non-knowledgeable mind. My MBP is running plugged in with the battery out and an extra monitor attached. These are my temperature readings based on iStat Pro:

    HardDrive: 39
    CPU A: 64
    Airport Card: 53
    GPU Diode: 71
    GPU Heatsink: 60
    Heatsink A:60
    Heatsink B: 48
    Memory Controller: 50

    Temperatures in Celcius. Computer has been on for about 2.5 hours.

    Thanks for your help

    My fans don't spin up until the computer reaches around 75ºC.

    Those temperatures are fine. It would be quite hot on the lap, but it's in no danger of damaging itself.

    I highly recommend smcFanControl (free), especially for notebooks. I use my Macbook Pro on my lap all the time, and often times it gets absolutely unbearably hot to the touch - all I need to do it check the temperature SMC is reporting and bump up the fan RPMs.

    By the way, my record core temperature is about 92 degrees Celsius. I believe it's designed to shut down in the area of 95.
