When I put the new board into the old case with only two case fans the board temps were 46-48C at idle while the cpu was at 42C. I was hot under the collar seeing those temps. So the new case was ordered and two additional 120mm fans saw the board temp drop to 31C and cpu at 32C. I break about 42-44C if I crank the cpu up a little. The newer boards seem to need more cooling then the older ones.
