If the system is not under load then it is getting too close for
comfort. Drill a hole in the side of your case so that a 90mm fan will
blow cooler air into you case and onto your video card & northbridge
controller.
On my system I have 3 80mm fans pushing air in and 2 80mm fans pushing
air out. While overclocked from 2.8 ghz to 3.33 ghz in 26C ambient
room temp idle temp is 28-30C and full load temp is 47-50C.
I also installed a fan speed controller so that I can increase or
decrease the fan speed depending on load.
Works good for me.
