    I just got SpeedFan 4.37 for my Windows partition on my MacBook Pro (early 2008). Can someone tell me which areas the readings are measuring?

    My Understanding (correct if wrong):
    GPU: Graphics Procesing Unit
    HD0: Hard Drive temperature
    Core 0: CPU Core 1
    Core 1: CPU Core 2
    Core: ???????
    Ambient: I guess this would measure room temperature if my computer had that?

    SpeedFan is a reliable and accurate temperature gauge, right?

    BTW, hit a high of 77 degrees celsius (170.6 degrees Fahrenheit) while playing Civilization 4 on the Windows side. My searches show that these MBPs can handle up to 95 degrees Celcius without getting into trouble, right?

    Are there particular areas that are more heat sensitive than others, like the GPU or Hard Drive?

    100 Celcius degrees is max junction temp of GPU, CPU. 77 Celcius degrees during hard core gaming is OK especially for NVIDIA chips. If temps are around 95 Celcius degrees I should start to worry about your laptop.
