I just got ATI 5850 and a more powerful PSU which start to raise my hardware temp.. the cpu temp is fine, but the graphics card is about 49 celcius and the motherboard is at 63 celcius. the fan is at about 1900round/min when i am not gaming. i think this is little high... so could I do anything like adding an additional fan or something else to improve this situation? thx in advance!!
