Problem with the CPU temperatures

Back when I had the Asus A7V8X-La Board the temp was around 60C idle there is no telling what it would say when loaded, however using Asusprobe it registered 42C Idle 64C loaded.
Temps dropped to 52C in the bios and 37-54 with Asus Probe when I changed the cooler. Which one is more accurate, the Bios or Asusprobe for that board?
I replaced that board with an Asrock K7S41 and using the cpu cooler ( a Dynatron 60mm with a copper heatsink)the Bios now says 49-51 Idle 57 loaded. I tried the Motherboard Monitor 5 but it says 127C and cpu both. Speedfan does not work with this SIS chipset I guess, it gave me a time out error message. I do not know which utility I need to use in order to get an accurate temp reading.
I did not reapply any of that thermal pad because it seem to have enough on there and I did not have anything CPU paste anyways.
I also installed an evercool aluminum 92x92x25mm rear fan which pushes much more than the previous one.
Is the Bios giving me an accurate reading, does it look about right? Surely temps didn't go up because I changed the motherboard.
The Bios is V1.7 which is the latest one
Thanks in advance
