http://overclockers.com have an interesting article here (http://www.overclockers.com/articles1246/) on thermosyphons. Very interesting read! Can't wait for commercial products to hit the shelves!

Interesting but their test results seem a little odd. Early days but one to keep an eye on.

Yeah, I found it odd the results didn't vary much with fan speed.

Or with load. Idle/Load seemed very similar which either suggests remarkable efficiency or they didn't leave it long enough. In at least one of those tests Prime95 only get to the third line. I would have thought they would have left Prime95 running for a lot longer than that.

Have you seen that Joe Citeralla now has a commercial interest in the Thermosyphons kit? I'm not saying the Overclockers reviews are biased but they are hardly independent.

Whats new?

There's still the problem of getting all the heat out of the case.

And I'm used to seeing thermal resistance quoted in degrees C over Watts - where the best cooling solutions had the lowest numbers. What were they graphing? If it's thermal resistance, then the new solution is worse than the air cooling setups.

Athlon 64s and Opterons don't have individual thermal ratings; a range of cpus get a max rating. For example.. everything running between 1 Ghz and 2 Ghz dissipating less than 89 watts.

It also brings to mind the earlier claims that liquid metal cooling was going to be the future of graphics card cooling - only to have it shown that having a liquid metal with much higher thermal conductivity than water doesn't help much if the bottleneck is the heatsink that's being used.

So how long until the independant reviewers give an in depth and well researched review?
