Air better than Water?
 

At overclockers.com, i saw Cathar's WW with a C/W of 0.19. The best among the water ones.
But i also saw an SLK-800U, with an C/W of 0.15!

Does this mean the SLK is better than the WW?

Tested on different simulators so not directly comparable.

If BillA didn't do the testing, you shouldn't trust it. There are too many out-of-the-ass numbers out there.

I can by and large reproduce the relative ranking of JoeC's numbers in his heatsink roundup with an internal diode. If you look at the simulator he uses though it has a huge copper socket up top, and so much more heat gets dissipated by simulator/air interactions than with BillA's simulator (or even with my CPU diode). So the c/ws that JoeC gets are a bit on the low side. Relatively speaking though they are fine.

Maybe if you dont mind your PC sounding like a B-52 bomber!!

Watercooling is almost silent and performs much better at load than air.

I would love for someone to show us otherwise.

lol my bad, one was on a die simulator, the other was on a board :(

sorry.
