Asus P4266 MBM5 readings

I have Motherboard Monitor 5 installed for Windows XP with Asus P4B266 running P4 1.6A OC to 2.24. When I check my temp readings in MBM, I have sensor 1 set to ASUS 1, Sensor 2 set to ASUS 2 and sensor 3 set to ASUS 3. Now at CPU idle, sensor 1 and 2 read 28 C and sensor 3 is at 125 C. At full load under SANDRA BURN-in for 10 hours, sendor 1 is at 30, sensor 2 is at 40 and sensor 3 is still at 125. I assume that sensor 2 is my CPU temperature? Is this correct? It seems kind of low to me.
 
I keep reading that MBM doesn't really support the P4B266. The bios locks the cpu temp at 40°C. I'm waiting for a new bios. I checked the asus website and they don't even show a beta bios available. 🙁 I have my 1.8a running at 2250 right now but it will do 2.4GHz...had it there last night for a bit, but I don't like doing extreme ocing without knowing my EXACT core temp...this is suck!
 
When I tried CUSL2 for the CPU, I actually noticed it rise during the Prime95 torture test I ran for 2 hours. Started at 38c and rose to around 48c. Once I stopped the test, the temps dropped back down to 38c after a few minutes and have stayed around there since. May have to play a game like MOHAA that was known to give my previous setup a good temp rise.
