[i_am_str89]

Hey dudes.I have an ASUS 8600GT 512DDR3 at stock speed but its idle temperature is bout 59C and when i'm surfing or watching videos it becomes 64C.When i'm gaming it continues to rise upto 90C+.I dont get it.I've opened the case and checked everything but nothing's wrong except it really heats up fast.What can i do?
