Soyo on die temp ????

[Beaon]

Wondering if ne one else has had this problem.
A friend of mine recently put a computer together concisting of a soyo kt4 ultra plat edition.
We had tons of problems setting up and found out that the "on die" tempurature reading was coming up wrong.
As soon as we boot up we see that the on die is reading to be 80c according to the bios. We know this is incorrect quiet simply to the fact that when we put our hand down to the bottom of the heatsink it feels like room tempurature. Now you guyz know that when the core of the processor gets passeed 60 you can very well feel the air temp be warm near the heatsink.
So we assumed that the on die reading was wrong. At the same time there is another reading that says "CPU TEMP" which is right next to the on die temp. The CPU temp looks like it should when you boot up, running around 30c or less. in other words room tempurature.

Now we know t he processor isnt overheating, first becuase we physically can see its not hot. 2nd you can chain run 3dmark03 for hours without it crashing.
So after its all working you ask, then whats your problem beaon?

well.. the motherboards "anti-burn" settings read the On-Die temp. It shuts off and sounds the alarm once the on-die passes 80. And the motherboard thinks the die is passed 80 right when we boot up. We have to disable the anti-burn settings to get it to run.
This is rather inconvenient when we want to overclock his 2500 xp. We are quiet lazy and like to use our motherboard as our failsafe to immediatly turn off the system when the core gets to hot.
But since our anti burn must remain disabled for our computer to function we cant do this.

My question is have ne other soyo kt4 ultra plat edition users had the same issues? We recently upgraded the bios not to long ago. But maybe it is a known bug and they released a new bios flash? Or could it just be us with a faulty cpu themamature. Maybe the anti-burn should read the processor temp, and not on-die temp because the bios vers. is faulty and the on die temp is incorrect, while the regular cpu temp looks normal?

thanks for the help
