Just installed Mountain lion on my hackintosh just yesterday. left my computer on all night as i usually leave my computer running 24/7. woke up in the morning went to my computer to check my emails. walked away for a minute to do something came back and screen connection was out. hit the keyboard and nothing. i looked in my tower and touched the Graphics card and it was extremly hot! and being that i have the ac in the room on all night i dont know why this is. it was so hot all i did was touch the plastic casing and it burned my hand.
restarted the computer and nothing. i took out my graphics card, took the casing off and the heatsink off... cleaned out the single fan and removed the thermal compound off the gpu and heatsink. put on some artic silver. spread it out evenly with a debit card. put everything back in and still nothing. then i decided to take out the graphics card and put it in the slot below and it worked. i dont know maybe it burned out my first slot. then when i left my computer on for about 20 minutes touched the graphics card again and it was extremly hot again. i dont know if my graphics card isnt compatable with mountain lion i mean it works but maybe mountain lion demands something more then gtx470? it worked fine with my snow leopard not sure about the temperatures because i never checked. i have dual boot with windows 7. ran that for about 30 minutes and the graphics card temperature was decent.
im not sure whats going on if i had to guess maybe its the settings i put in for multibeast screenshots below.

i also contacted a friend of mine who also build computers. he mentioned 6 months ago when he first made a hackintosh he had 2 evga gtx 460's and he said they were damaged in snow leopard. same issue he said they were overheated and he had to send them back in for warrenty because they were acting funny when he was gaming on windows 7.

my systems specs are
sabertooth x58 MOBO 1304bios
i7 950 w./ prolima megahalems
evga gtx 470
G.SKILL Ripjaws Series 4GB x6 clocked at 1600mhz
x-fi sound card
corsair tw950w power supply
crucial c300 128gb SSD
4x western digital black edition 1.5tb 64gb cache
western digital black edition 2tb 32gb cache
 
What temprature is it?
 
i dont know how do i tell? I've read some articles saying that mac temperature monitoring programs are inconclusive or inaccurate on a hackintosh. so i really have no idea of figuring out how hot it is.... i can switch to windows 7 and use the temperature program that came with the graphics card. but then again the graphics card temperatures are normal when on a windows operating system. all i know is that the dam thing is hot and i can now only leave my computer on for about 20-40 minutes before it gets extremely hot again.

this is what my setup looks like from my youtube channel

I'm having a similar problem with my EVGA gtx 470 SC too, it freezes up anytime I run something GPU related (after about 5 mins or so), and I have to reboot the computer. I think it has something to do with the fan speeds - on Win 7 I'm able to set the fan to temperature curve so that it increases faster than what the BIOS dictates, I used MSI Afterburner for that, but on OS X there is no way to control fan speeds. Have you determined if your fan speeds up when you use a GPU intensive app? If not, then that could point to something. I'm looking into getting an external fan controller for my card, as I can't afford to upgrade at the moment. Short of using a hex editor to modify and reflash your card's bios I don't know any other solutions...
 
ofcourse the card works fine. i got mine connected to a 55inch Led samsung 240hz tv and its handling pretty nice. but the graphics on mountain lion are awesome way better then windows 7. and i dont know i guess mountain lion demands more graphic performance from the card. the issue that im concerned with is that not that the card still works cuz it does but the fact that its getting extremly hot. i put my hand on it and it feels like im putting my hand over a pot of boiling hot water. i mean im really loving Mountain lion and i would hate to downgrade back to snow leopard. but im more concerned that the card will burn out if i dont keep checking the card ever hour im running it to make sure it doesnt get to hot, im touching it right now and im guessing its about 95. for the last 2 days ive been turning off my computer at night when i normally keep it running 24/7.

i was thinking of taking the plastic cover off the graphics card and mounting a high speed fan to the heat sink. something like this

i think it would effectively cool down the card but it would also be very loud.

and im also concerned that the card does have some damage to it, the only way of finding out would be to test it in windows 7 with a high peformance game and see if it doesn't glitch of flash or the screen goes blank... that happened to my friends hackintish with gtx 470 sli. the card still worked but it proved useless when gaming.

my only alternatives im thinking would be to either downgrade to snow leopard or
buy a higher end graphics card
or invest in a water cooling system which can be expensive to get and maintain.
or make a modification to my existing graphics card. mount a fan with a high CFM

i would really hate to put aside my gtx 470. it does have a lifetime warranty. HAHA
 
Does you gpu fan spin up to indicate higher temps? Maybe you should make a custom entry in AppleGraphicsPowerManagement.kext to keep the power down when your computer is idling.
 
i think maybe the fact that the system preferences are on 60hertz with top resolution is the reason my graphics card is over heating. i tried playing with the settings a bit but anything under 60hrz and 1080P looks crappy.

I don't think that's the problem at all. Try editing the AGPM.
