Here is my setup: kt7-raid, tbird 1100 @ 1250mhz,globalwin fop-32,artic silver,Coolermaster atc-201 atx case w/400 watt psu(this case has four 4" fans two in the front blowing on the HD's,one on the top and one on the back right above the cpu).
My temps are 32-38c cpu,and mobo 18-22c (fullload)
I think the reason these temps are so low is becase of the volume of air flowing through my case,but one drawback is its louder than my fridge.
