    On a 6 core/D700 nMP I'm seeing GPU temps under Windows 8.1 of 78-82C when doing anything graphics wise under bootcamp.

    Haven't been able to find any software that will allow the user to control fan speed when gaming or processing video. The machine does feel hot with a little smell when doing any light gaming. It's difficult to see if the fan is spooling up and there is no output of the fan speed (shows fixed at 20% under the GPU monitor software)

    This is with the latest bootcamp drivers installed, along with AMD's Catalyst Control Center installed for control. Any ideas would be appreciated, including whether this is a "normal" GPU temp for the D700. The CCC does not show a readout of the fan speed or GPU temp. Has anyone tried downloading the AMD over clock utility to see if that will allow for control of fan speed?

    What I ended up doing to mitigate the heat problem was to manually increase the fan speed while in OSX using iStat Menus, then booting into Windows where the fan speed is retained. SMC Fan Control works too.

    While the cards never got above 85C, there was an annoying smell associated with the load on the system. Fine now.

    i wonder why the fans don't start earlier on windows under bootcamp, is your mac pro running well now? so basically once the fan speed is set in osx it remains in windows too?

    Thanks..

    Yes, that's how it works. Just check for airflow to make sure the fan is running at the selected speed.

    If you have a nMP, only Windows 8.1 is supported by bootcamp. I never tried any other OS.

    i got a late 2012 27" iMac & its allows be to use windows 8.1 via bootcamp, regarding istat menu, was it easy to change the fan speed? also you change the min idling speed of the fan? on the new slim iMacs the idle speed of the fans are only 1200rpm which i feel is very slow.

    Thanks..

    Any form of Windows 8.1 will be fine.

    Myself, I use Windows Embedded 8.1 Industry Pro because I use it for creating custom bootable images to be deployed on client systems throughout my organisation.

    But other than that, it's just a regular Windows 8.1 Pro with all the extra features for embedded systems in it.

    If you're a student, you can get a copy of Embedded 8.1 Pro for free from Microsoft under the DreamSpark program.
