So lately when I play games, I play for like 30minutes and my computer shuts off. I downloaded speedfan, and it says my graphics card is at 70 C at idle. Then when I play a game speedfan says it's at 105 C. The fan on the graphics card is still running and seems to be fine. Also if anyone has speedfan the temp3 is at like 60 C idle and 80+ C ingame, anyone know what temp3 is?
What could be causing my graphics card and whatever temp3 is to be massively overheating, and how can i fix this?
Prolly a hairball in the radiator/vent. Take the time to remove the card, give it the mother of all cleanups, make sure the heatsink is properly seated, and re-insert it.
See how that goes for the temps.
And while you're at it, you might wanna do the same for the CPU and the rest of the fans. A good clean-up goes a long way.
