There are so many variables in this factor starting with what your room temp is, airflow in & out, case size, & type of heatsink & fan combo. Each monitor program needs to be listed as you post the temps. I read that the Asus Probe does not read correctly that it reads higher & the different versions of bios makes it run higher too. I use it & it matches the Asus Bios hareware monitor. Going to switch to MBM 5 tonight. It is warm board.
My average settings are room temp 78*f, m/b temp 82*f, & CPU temp 41*C with my Swiftech 462A ( ASII) on low speed, full tower case, 125cfm + airflow in & out.
