OK, still wrestling with lots of other weirdness but I am still running a dead stock 4170 and it idles at 55 degrees. I am running a bunch of older processor and they idle in not as well cooled cases between 34 and 42 degrees. I have had three different processors in this board and they all run HOT! Thermal Radar sucks? Bad board design? I got a top rated after market cooler with Silver 5 paste.
