Ok I have a Soyo Dragon+ w/ an XP 1500+ w/ stock HSF and nothing is overclocked (yet). All of these temps are with prime95 running.

There are 3 sensors reporting temperatures to MBM5. Sensor 2 is constantly around 32C so I am pretty sure that is the case temperature. Then there is Sensor 1 which is always from 44C-48C. Finally there is sensor 3 that jumps from 20C to 58C back to 22C and then like 60C. It never stays at at one temperature. I just assumed the highest temperature would be my processor. Anyone know why sensor 3 is so sporadic? And anyone with a Dragon+ know which sensor is the cpu sensor?
