I have an Athlon II x4 640 OCed to 3.45 GHz, no voltage change.
I'm cooling it with an arctic cooling freezer 7 pro.

I was messing in the BIOS and decided to turn of Cool n' Quiet to get the most performance.

Before I turned this off, I was getting temps of 18C idle in CPUID
Now, after this setting has been turned off, at idle i've seen this thing at 4C, thats almost freezing?!

Does this seem right?
