I recently purchased a new motherboard, some lighted cables, and a Zalman CNPS9700. Obviously, I am going to attempt some overclocking. Before I made the changes, my AMD Athlon 64 3000+ was idling at 28C. After changing motherboard and cooler, I am idling at 40C and going to 45C while running Prime95.

Could one or both of my temperature sensors on the mobo be out of whack?

I am confused as to how my aluminum stock cooler was getting lower idle temps than a copper heatsink that looks like a jet engine.

My other problem... For some reason warpspeeder will not let me overclock. In addition, my bios has only 3 OC settings, +1.7% speed, +3.something% speed, and plus 5.something% speed. 5% speed increas falls a little short of the 500mhz or more that I had hoped to achive.

Am I just plain old screwed, or does anyone have any suggestions?

Hello, your power supply is hardly ever giving exactly the power it should. But it's usually still within a certain percentage and the power dropping to below 3V is probably over the borderline.

Check the recommendations given by your motherboard manufacturer on the kind of power it needs. You've got rather a large amount of power required to run all that stuff!
So the PSU is the first place I'd look.

As far as the temperature goes, maybe the core temperature of your new board has something to do with the increase on your CPU.

the other thing to take into account, is a less than perfect seal with your thermal paste, this can cause heat jumps more than anything else. Perhaps try removing, cleaning and re-applying your heatsink.
