I'm wondering at what temperature range a 7900 GT should be running at. Right now, with no games or anything running, nVidia MonitorView, (temperature monitor), tells me that the GPU is running at 53*C. I think that's pretty hot for just surfing the web...
My 6600GT (overclocked, btw) is 66*C, but I just got done playing some games. I don't know what the defaults say for you as the max, but for me its 145*C. My guess is the GPU's can take a lot more heat abuse than CPU's can. Also, I don't know how accurate these temperature readings are, so you do want to take them with a grain of salt. The key is if your system is stable or not. If it is, don't worry.
I think thats fine... "Idle temp 48, load temp 68. Temps are kept relatively cool by the small fan." (^comment made by "Brent C" on this page (LINK) ) there are similar comments scatterd through-out google...
