why u complain low temp on CPU?

I got similar CPU pentium Dual core E5800 but 800FSB version,

Stock @ 1.28v @ 3.2GHz (200FSBx16)
G41 mobo
Cooler Master TX-3

I manage to pull @ 3.73GHz(266x14) @ 1.29v

or

3.83GHz(333x11.5) @ 1.322v

So I think u can lower ur voltage down to 1.32-1.33v Not sure if mine is golden chip or not, because it can do the same 3.83(333x11.5) @ 1.322v only on Prime95 and battiefield3 beta a few days.

not bad for a old CPU to play latest game.
