TJN93 Posted February 1, 2013 Share Posted February 1, 2013 Hi, My graphics card is reaching over 70C temps when I am doing nothing, just sat at the desktop! It actually stays at exactly 72C and sometimes reaching 73C, it isn't just an error reading the temperature I can feel the hot air coming out of the graphics card it is actually hot. In Windows the graphics card will idle around 40 to 44 degrees, so there is something seriously wrong. Any ideas?

Gringo Vermelho Posted February 2, 2013 Share Posted February 2, 2013 Ouch, that's hot. Video card power management is not working right on your hack. Find and read threads about how to configure AppleGraphicsPowerManagement.kext AKA AGPM.kext. There's a ton of information available.

TJN93 Posted February 4, 2013 Author Share Posted February 4, 2013 Sorted it by changing the system definition to iMac 12,2 and then using the kext from here: http://blog.thireus.com/guide-hackintosh-install-macos-mountain-lion-10-8-on-asus-sabertooth-p67-in-3-steps Now the graphics card properly down clocks to 50MHz when not in use, idle temps are now under 50C which is great.

yourboyvic Posted March 1, 2013 Share Posted March 1, 2013 (edited) Sorted it by changing the system definition to iMac 12,2 and then using the kext from here: http://blog.thireus....-p67-in-3-steps Now the graphics card properly down clocks to 50MHz when not in use, idle temps are now under 50C which is great. @TKJ93 I'm attempting to apply the same solution you did for the temps on GTX 480. When you say change 'system definition' how did you go about doing that? I used iAtkos and not tonymac, so do you know a way to do it after installation? muIti8ea5t? Thanks in advance!

TJN93 Posted March 2, 2013 Author Share Posted March 2, 2013 Hi, I used ##### to change the system definition to iMac 12,2. Never used iAktos but i'm sure you wouldn't have any problems using ##### with that.

yourboyvic Posted March 24, 2013 Share Posted March 24, 2013 so this original problem of gtx 480 idle temps spiking up to 70 degrees is back again in 10.8.3 grabbed the kext from thireus blog for 10.8.3 and my system def. is still iMac12,2 so I removed applegraphicscontrol.kext to see if that will help. either of you two move up to 10.8.3 and experience the return of the idle gtx 480 temp spike? please report your results or workaround or fixes please thanks Gringo, thanks TJ Link to comment https://www.insanelymac.com/forum/topic/286064-gtx-480-over-70c-idle-at-desktop-ml-1082/#findComment-1900370 Share on other sites More sharing options...

Thireus Posted April 2, 2013 Share Posted April 2, 2013 Yep, the kext was not properly patched. I have uploaded a new pre-patched version. Now it should work. Otherwise try to patch it yourself .
