I'm visiting corsair's booth tomorrow if you have any further questions to ask. I'll check on availability and pricing.
The big thing to keep in mind about these, is if you want just the basic functionality you'll be getting your toes into water cooling for a very competitive price... And CoolIT has put forth that no air cooler can touch this.
The claim is that the C/W ratio gets down to .08, where as heatpipe designs can't really get below the .10 barrier. While the previous model was usually within a degree or two of top end air coolers in most reviews... In their testing, this new model lined up better temps than any top end air cooler with a 920 OC'ed modestly to 3.8Ghz.
Now, this will need independent testing... Why did they test at 3.8Ghz? Mostly people like to try to hit an even 4Ghz for casual every day clocks, especially if they have a "water cooling" system.
But, I could see how it probably is an improvement... As was mentioned, the flow pattern is nothing new in the waterblock market, except possibly in the closed loop coolers of this general design. Increased surface area and all. However, with channels like that its a fair bit of restriction also. Its a balancing game with a change like that between surface area and flow rates, and if they were careful with their revisions and testing, its quite possible they really got it right.
Can't wait to get one and put it in muddocktor's hands.
