Re: whats the best cpu cooling
1GHz from stock? Depends on the CPU, and I doubt you'd K8 to 4GHz, that certainly would be a feat.
I would recommend the Xigmatek. The Zalman 9700 is an overrated under performing pretty POS, and I'd expect the Xigmatek to outperform it even though it's almost half the price.
