How can I tell what temperature my 8800gt is running at?

    After playing a game in OS X for a while I notice that the graphics performance seems to degrade and running a cinebench benchmark shows 3000 instead of 6000. I'd like to check the temperature of the 8800gt. I have istats pro, but there doesn't seem to be an option to display either the fan speed or the temperature of the GPU. Is there anyway to show this information?

    I've wondered about this too, although for the HD2600s. I know
    on my iMac the GPU temperature and fan speed were available.

    I can detect the temperature on the 8800gt if I use bootcamp with Windows XP and launch nvidia ntune. It shows the temperature of 51 degrees celsius and a fan speed of 675 rpm.

    But any of the applications in OS X like temperature monitor or istat don't detect a temperature sensor on the 8800gt. This is strange

    Mine runs 59ºC in Vista with a few windows open. fan is at 196 rpm, however this is one of the nVidia reference designs (MFG by BFG, running 626/900). I'd also like to point out the "alarm" temp on nTune is over 190ºC.

    What program do you use to monitor temperature in vista? I am doing a POV-RAY render right now going on 20 hours with all 4 cores pegged @ 100%...

    Download and install nTune. It adds the ability to overclock your nVidia based card, as well as introduces monitoring features. Works right with your drivers.
