CPU using too much power (95w cpu @ 100.7w)

Specs: Windows 7, Phenom II x4 945/4GB RAM
I just installed a Phenom II x4 945 c3 95w CPU but HWMonitor shows it's using 100.7w under load. My motherboard, MSI K9N6PGM2-V2, does support this CPU but it only supports CPUs up to 95w so I'm a bit worried. Everything in my BIOS is set to auto (AMD Cool'n'Quiet is enabled should that matter) and I'm not using any software in Windows to overclock. The temps at idle are around 29c, under load at 48c. Is there something wrong either in Windows or my BIOS to cause this, or is this normal?

I wouldn't worry about it. MSI lists the CPU, so the board was made to handle the load that processor puts on it. Just don't overclock it.

AMD's website states the voltage range for that CPU is 0.80v to 1.40v, while set to Auto my BIOS said the CPU voltage was at 1.325v. I reduced the voltage one step at a time until HWMonitor reported 95w usage and ended up at 1.25v. I assume it'd be safe then to run the CPU at that voltage? Would I need to disable Cool'n'Quiet to make sure the voltage didn't drop below 0.80v when it went idle?
