Better than water? .16C/W on AIR?

.16 C/W.

The best waterblock tested by Joe C. came out at .13 C/W. Add a radiator, which is .02C/W in a good situation, and you're pretty dang close, like a difference of 1C loaded.

The benefits of water are MUCH quieter, as well as the ability to add a pelt.

The sp-94 is better anyway.

At equal noise levels, they're about the same, but htanks, I didn't think to look at the P4 rankings.

I don't think the C/W ratings for P4 heatsinks, socket A heatsinks, and watercooling setups are comparable.

The SLK800U on the P4 simulator gets a .15 c/w, while the SLK800U on the socket A simulator gets a .23 c/w because of the difference in die sizes.

Also keep in mind that even the best watercooling kit tested by Joe isn't going to be comparable to an all-out custom setup.
