It's cropped a few times now that one over the last few years... we're still waiting. My worry is that it'll go the way of the magnetic liquid metal cooler we saw a few years back that was completely passive, cooled twice as well as all the current models and cost 4 times as much!

Also of note cooling wise last week on Hexus:

The inital white paper was doing the rounds start of 2010 (as you can see on the date stamp) and it was one of the Intel channel techs that brought it up when we were looking into some crazy server cooling for a corporate client back then. I was under the impression that it had been circulated more widely than that before this point althrough now I look around perhaps not.

In the early days of carillon we did look into noise cancellation - being like audio buffs and everything we figured we could place a microphone inside somewhere, invert the phase and blast it back out through a speaker - job done. It was all just a bit too much fiddling and the most likely thing to wrong in any given system

I remember this from some time back too. I was impressed with the level of detail in the original paper. What I particularly like is the way they took known physics and just tweaked things a little.

I'm sure this will take time to develop, and probably some serious funding, but the first prototype looked very promising. I expect the real market will be in large air-con units rather than piddly little computer coolers

The news seems to be all over the web at the moment, with people gushing about how it will replace every heatsink and save the planet. According to this, "the team has come up with an updated prototype that is nearly ready to come to market."

No way am I sitting a thousandth of an inch away from my aircon unit. Damn thing's noisy enough as it is.

Are you referring to the Nofan CR-95 coolers pete? I've heard really good things about them, even seen a guy who used one to cool a completely passive quad i7 system which after 30 mins of prime still didn't go over 80 degrees. The price seems to have come down a bit but they're still about £80.

I'd like to know which one too because the Danamics ones I tested were utter garbage despite the hype!

I love the concept and I quite clearly see why it was likely to go very, very wrong. Kudos for giving it a pop through, that would have been a fun few days!

Nah, I quite like those even if I get the urge to sit a hamster in it. It'll do up to 95w TDP which allows you a low end i7, althrough I tend to use a low power (S edition) version of the CPU to keep thermals as low as I can.

It was the original release of those I was refering too (or at least the hype it seems). You got further than I did mind, as I saw the supposed scores, got quite interested in the product and then they came to market at about £180ish I stopped bothering trying to obtain a sample. I see the baby version is available now for around £80 with fan option... think I'll stick with the CR-95.
