    With istat pro, it is reporting that my ambient temperature is 36, while it is only 23 in our place. Everything else is very low for the temp:

    HD 29
    enclosure base 1,2,3 29,29,30
    heatsink 37
    mem bank 34
    mem module 42

    Anyways, why is it reading that the ambient is so high?

    Do these things even have ambient air sensors? Maybe the istat pro widget is picking something else up?

    Sunny but Cold.. Canada
    Ambient is a relative term..

    I cannot say, but let's guess that the ONLY Ambient the computer can sense is the area surrounding the unit itself.. Maybe it IS that temperature nearby.. There are obviously No Remote Probes involved.. Methinks..

    Someone wiser than me will perhaps chime in here.. I'm curious to know as well.. ;)

    It's odd because in all my searching online I can't find anything like this. Maybe it's okay and I shouldn't worry. I just don't want my fan kicking in because it thinks it's too hot or something.. maybe the ambient temp doesn't have anything to do with the fan, I don't really know..

    CPU and GPU temps are what matters to the fan's algorithm, the rest are for informational purposes only.

    It's not like there's an ambient air sensor sticking out of the Macbook, so it can't take an actual ambient temp. Maybe it's the incoming air which is already being heated up a little bit and the sensor is within the case.

    Ambient temperature is the temperature inside your Mac, but not attached to a processor or heatsink. It's usually mounted somewhere on the motherboard away from the other components.
