When are you going to get the Nexxos XP? That's the one I'm looking forward to. It'll go well with the Koolance Exos I'm going to buy.
As for this flow rate argument...as much as everyone drones on about flow rate being the most important aspect of cooling, it gets pretty tiring, but I grudgingly have to agree with them. Every waterblock test shows this. Just look at Phaestus' innumerable charts. But these are American waterblock designs that rely on flow rate for cooling.
It seems to me flow rate has less of an impact on waterblocks designed for 6mm tubing than it does for waterblocks designed for 3/8"-1/2" tubing. They weren't engineered for the same purpose so a direct comparison can't be made. In a 6mm system, their designs have been optimised for low flow rates, as a result of physical constraints. You can't force 2+ GPM through 6mm tubing. You just can't. So low flow systems capitalize on radiators being the most influential factor in the loop. Drop the temperature as much as possible before returning to the CPU. Instead relying on thermal capacity (like a high flow system), it seems to me that low flow systems rely on temperature differential for effective cooling.
Or maybe I'm rationalizing a flawed design?
