the water cooling makes a BIG difference, it would seem.
if you had the inclination, apokalipse...maybe you could take the water block off and put a stock cooler on it. just for information purposes. not really neccessary, but i bet it will jump in temp 7-10*, don't you?
and i just noticed its 41* at idle, stock voltage. that is indeed a little high...i think my 4200 idled at like 30-32* with stock voltage and a zalman, and it is a 90nm windsor...
