Everything was fine with my GPU until around a week or two ago. I noticed my computer was running loud and checked my GPU software and it said that my computer was running around 70C with the temperature being around 76 (Fahrenheit) inside! I turned it off and let it sit for a while and turned it back on and it still went up to 70C!
Before when I used my computer my GPU would run around 35C on idle when the temperature outside (I keep my windows open for anything under 72F) was in the 60s, but now it is in the 60s outside with this recent cold front and my GPU is running close to 55-60C on IDLE.
Here is a pic of its current status (Room temperature < 60F):
I just took the manufacturing thermal paste off and put some Arctic Silver on it and the temperature came down to around 50-55C now, but that is still WAAAAY to high for a computer on idle.
My air flow in my computer should be fine, it was working fine how I set it up a few months ago, I have just recently started having problems with my GPU, but haven't changed a thing on the inside of my case.
