It's a supermicro mobo in a supermicro tower server. 10 minutes into a parity check the drives are all 22-24c, CPU core avg is about 26c and intel5500 peaked at 89c. I pull the side of the case off and put it on it's side so the heat could rise off the mobo and the intel5500 temp has fallen by 3c so far. The chipset, where I assume the temp is being measured, all has heatsinks but no fans.
The CPU and drive temps are all good so I think there is enough airflow in the case, but not enough airflow over the chipset to keep them cool. I'm going to check all of the fans and the fan directions to see if there is anything amiss.
