My AMD Athlon II X4 645 runs at 20C when near 0% and runs at 25-30C when at 10%-20%. I'm using the stock cooler. At 100% it peaks at 60-65C after about an hour before it starts underclocking. Is this too cold? Should I overclock it somewhat?

It's pretty much impossible for a chip to run too cold on standard cooling.
The only time they do technically run too cold is under liquid nitrogen at around -80c.

Overclocking won't really change your idle temps much at all, just load temps. If anything, the chip is running too warm under full load (62c should be the safe limit).

Idle temperatures are only really going to reflect your ambient air, or ambient case air.

Unless you see snow exhausting from the back of your PC you are fine.

When it comes to PCs, there really isn't such a thing as "too cold" when running on air or water cooling. Your CPU is still above your room temperature, and even if it was equal to room temperature (which you would need some incredible cooling setup to achieve) it would still be perfectly fine.

Basically, if you aren't using sub-zero liquids to cool your PC then there is no such thing as too cool.

You do know that 20 Celcius is 67 Fahrenheit? Probably below ambient temps in your house. Which is pretty much impossible unless you are using chilled water or exotic cooler. The temperature isn't accurate till you put a load on the cpu. It is a well known problem with AMD cpu's.
