Help me understand CPU-z

[OS-Wiz]

I bought the coolermaster Hyper 212 plus and installed it today. It is amazing.

Stock cooler: 3.15 Ghz, prime 95 tested and max temperature 86°C
Hyper 212 plus: 3.46 Ghz, prime 95 tested and max temperature 57°C

I can overclock farther and run cooler.

Seems you have done a good job mounting it, that's a great temp considering your OC! I'm still amazed at how well that little $30 HSF works -- truly outstanding!
