Dude, all programs are sketchy, simply because the onboard sensors are sketchy in the first place. I'd just go with an average of the collection if any at all. Temps shouldn't be any different between the programs? Make sure your programs are reading the right sensors... MBM is a pain in the *** having to select/guess which sensor is what based on BIOS and Sandra temp results.
is there anything that is more simple than MBM5 i have that problem too-not so much on previous systems iv been working with but this Soyo TISU is a nightmare i cant figure it out nothing looks right, one sensor gives 17 celcius then im getting 117 c. crazy
This motherboard (GA-7VAX) uses the LM-90 remote function on MBM, which reads from the probe in the CPU and I hear that it's accurate, but I have no way of testing, myself as temp probes don't let the HS sit properly on the CPU.
