OP is... missing?
I like HWMonitor actually. I also use RealTemp. Never liked SpeedFan.
You can see here, RT seems to report higher CPU temps. But I noticed that Core 0 and Core 1 actually always report the same as CPUTIN and SYSTIN in HWMonitor so I'm not sure which to believe... I prefer HWM though as it shows me a lot more info.
