GTX 260 overheating?

My GTX 260 seems to be overheating. I assume it's my graphics card because I leave it on idle for hours without problems, however, when I begin playing a game that utlizes my graphics card such as Call of duty, Battlefield or Wow, my computer shuts down without any prompts. I feel my hard disk and my gtx and notice they are extremely hot. I have 3 fans. One on the side from the panel and one on the back. This was not happening before and it might be the fact i havent dusted it out i na long time. Is there any program that will collect temperature readings so i can give you guys or something?

 

Your graphics card will run hot during gaming and if the system overheats it will shut down to avoid damage.

this will give you the temps and much more.

I am not sure how savvy you are with the interior of the PC but this works if you can do it.

GPU-Z is a good tool.

 

BTW, I have a GTX-260-216 and it doesn't cut out even at 105C on auto fan speed. Have you manually set the fan? Something else that comes to mind is your power supply, what's its watts, brand and how old is it? Just some musings.

Oh, at %100 usage, my board is at 81C with the fan @ %55. Load up eVGA's Precision(works on other brands too) and see what happens. You could also run OCCT which will stress your rig to it's utmost and give you tons of graphs up until the machine shuts down, a very handy tool IMO

 

According to these tests, its my CPU over heating. It's at 99C right now and im playing WoW.

 

Your CPU is definitely hot, make sure the heatsink on it is not full of dust and that the fan is operating correctly, it also may be that it needs some new heat transfer past between the CPU and heatsink.
