Okay.

So, I have NVIDIA GeForce 9800GT 512Mb graphics card and I need to know at what highest temperature can it go
without overheating and crashing my PC since whenever I've been playing a game for longer then ~30mins the whole PC crashed
because the GPU were overheating.

When I took off part of my PC's hull and lowered game settings the temp were holding on ~75C(~165F) for about 30 minutes
and then it were slowly rising to +90C( 190-200+F) and then I turned the game off since I was afraid that my GPU may overheat.

Right now the temperature is ~55C(~131F) and I have two Firefox windows and Everest (program that I use to see what temp my GPU is at) running.

So, how high can my GPU temp be without overheating it?

Note: My cooler is not working properly.

Yeah I remember you were talking about this in game. It was like 90 C when you were playing... not very healthy.

Get a new/proper cooler?

When ever the thing gets hot,

Just dump a bottle of water on it. That should do the trick.

Order some fans online for 10~$ for a set of 3 powerful fans and get better air circulation to your system.

Older cards have thresholds of 90C. But I say nothing over 80.
Newer fermis can go well over 100.

I heard some people saying that Nvidia GPU's can go up to 120C without overheating.

Anyways I decided to try clean it out a bit.


It didn't helped though.
When I turned on my PC temp were going up to 80C and then fan increased its speed
and got temp down to 66C.
Right now its 72.

When I was about to post my fan increased its speed again and brought temp down to 63.
Now it is slowly rising.

EDIT: I think it did helped because my GPU is at ~85C when I'm running Gmod on max settings.

9800gt is known to run hot.
Its a single slot card anyways,

Buy a water cooled graphic card   

The hardware also needs water
