So i got a new used card and it seems to be running fine. But when I wanted to check my card temps I realized that a catalyst control center showed the GPU temp as (0). Clearly it's not 0 degrees. And Everest home edition didn't show the GPU or CPU in the "sensor" section at all. This is really only a concern for me because I still have my **** stock dell case and the air flow inside is almost nothing. Right now I have my card's fan running while i'm merely posting on a forum. So help, please?
