I used to use HW monitor also and got high temp readings so I switched to real temp and got better results. With HW monitor and when doing a stress test I was getting temps over 91c and the computer was not shutting down which should not happen because the thermal shut down should happen at 91c. So that's when I switched.
Another thing that you'll find is that software that you pay for will work better then free software. So when I get a software program that I like and want to use to a better performance I will buy the upgrade and get better more useful features.
