I finally got the core temp of my phenom lower than my previous of 26c to 23c! This is with C1E and Cool N Quiet enabled!

Used the Gigabyte overclock tool to check the temp, and there it was 23c. My setup:

Cooler Master HAF 932 (un-modified)
1200 Watt Power Supply (A-Power ACE)
Ultra ChillTEC cooler ULT400017 (I think that's the model)
Phenom II x4 945 125 TDP
8 GB of 1600 MHz RAM@1.65 volts - 9t-9t-9t-24-2T - DDR3

I didn't overclock. All I did was remove the extra metal appendages that you remove to insert 5.25" devices from the Tower. Voila! Inside case temp is 24c, and CPU core temp is 23c! Room temp 27c!

Ridiculous!
