Awhile back, I had the V card installed by an employee at best buy. But nowadays, the temperatures reach 60-70C on standby, and peak to 90-100s during gaming! I underclocked the card to prevent a crash, but I wish I could actually use the card instead of bottlenecking it. Any ideas..?
Thats not a good idea. The case is designed to bring air in and remove air out if properly setup. Getting two years of service out a gpu is not bad. Maybe someone else can jump in but it sure sounds like your card is dying.
One thing I would do is check your GPU and maybe reapply some thermal paste to see if that helps. Underneath that fan is a heatsink much like a cpu. It might help and be worth a try. If you have not done that before, I would start another forum and request help on removing and reapplying paste to a GPU
did you mean you already blow the heat sinks with compressed air? if you don't want to get new card right now try replacing the thermal paste. for 2 years the are high chances that the thermal paste come with the gpu already dried up.
