I play WoW a lot. This could be the reason my video cards keep dying after 3 months. If I just get a new heatsink would that fix the problem? I'm unsure of what kind I would need.
One of my fans wasn't running properly, I got it working again and my GPU has gone down about 4 degrees in a couple of hours as a result. I think it was just an issue of lack of air flow.
Do you have a Pentium Dual Core, or an actual 'Pentium D' (D's were 800 and 900 series, so 8xx or 9xx)?
If it's an actual older Pentium D, they typically ran a bit on the hot side, so you may not be as bad off as you think. If it's a newer Pentium Dual Core, then maybe other issues with dust or airflow. Was the fan you mentioned one of the case fans?

Yeah, since those were idle temps for the GPU, it was a bit high. If that CPU is a Pentium D 805, then you are running hot. Check to make sure your heat sink isn't crusted with dust and that its fan is running well.
