leaderroy never never trust software for subsero temperatures , Trust the Unit temperature readings as it will be as close as it gets. One thing i can tell you is that unit is not design for that much load on a cpu , so in fact you might see + temperatures while running extensive and intensive cpu benchmarks , it cannot handle that load simple as that. for accurate Temps reading i would suggest what i always do when im runing my 2 Stage Blue Cascade , insert a k-type probe directly touching the cpu , read it from a digital thermometer/DMM will be 100% acurate temperatures. I had many Single stages before and they are not capable of holding big loads , thats your key right there maybeyou are expecting too much from this little unit. i hope that helps you understand it a bit better. * also you never mention voltage and mhz you were running on that 12 treaded beast cpu*
