    CPU Temp Soars

    What exactly makes a CPU temperature skyrocket while leaving the GPU temp low?

    Right now I am writing an essay on Word 2008, have a powerpoint open, this safari window, and uTorrent downloading torrents.

    And my CPU temp rose to 83 degrees C after opening uTorrent.

    Why does uTorrent cause such a spike in CPU heat?

    It has now reached 88 degrees C and the fans haven't started to speed up yet. Normal?

    EDIT: I purposely opened up HD Youtube videos and the temp reached 90 C and the fans kicked in. I guess it's all good.

    Apple usually tends to let the components run hot, with the advantage of less fan noise and the disadvantage of longer wear over time. Still, 90ºC is still a safe temperature I think. The threshold for Intel CPUs is 105ºC.

    you can try using transmission instead

    My temps rise up to the 70's while using uorrent. To the OP: Check that there's no background application which is running and is eating up cpu resources.

    My macbook has never reached 60 degrees. I think 83 degrees for doing those simple task are so high. You should ask a genuis to check on it.

    it has little to do with the simplicity of the task, but how badly the program is written... if its using a lot of processing time and hitting the processor hard, even if its something simple, it will create a lot of heat... its pretty normal.

    Yes, cpu intensive tasks tend to heat up the mac quite quickly and to a high temperature.

    I have Word, Excel, Encorage, Firefox running at the same time, and the CPU temp is 56. Moreover, I use it on a lap. Did I mention that is hot as hell in this desert city?? My macbook white is used to be cooler
    CandianDude have the same thing running and he reached 86 degree C

    I'm running Transmission, FireFox, Adium, iTunes, as well as a VPN client and my MBPs temps are at 113F (44C).

    My macbook gets the most noticeable temperature rise when I am listening to music and watching movies.

    All this time, I kept getting nervous when my Mac Pro got over 40°C. (Lowest temp was 25°C, highest was 51°C).

    Those things are cooking!
