Usin Asus Probe, you are able to obtain CPU and Mobo temperatures, NOT the "chipset" temperature. I know it runs quite hot, but as long as you have decent air flow over the motherboard you are ok. Make sure your chipset heatsink fan is spinning though, or simply upgrade to a zalman if you have good airflow.
My A8N Sli Premium reports mobo temp from 36 to 44 depending on the room temperature.
