Those temperatures are low. I too am using Asus Probe V2.11, and have an overclocked Pentium3 600E @ 840
My idle temp is 54 deg Celsius processor, 24 deg C mobo. When I play games like quake, or even running RC5 the temps sky rocket to 65-70 degrees C or 150 degrees F.
btw, I have applied a thin amount of thermal paste, and musing a dual fan intel HSF and everything is secure. I've had no problems with the OEM fry's bought processor and have had this computer for 2 years.
I guess that means the program must be messed up...
U sure your bios is correct, cause 30 degrees C is cold for a processor using just a HSF.
