Pros: Extra Thick, Size to Performance Ratio, Low Resistance, Excellent Finish, Clean
Cons: Size, Weight
I've had the priviledge to use this radiator in a recent SFF build and it's been a great performer when paired with Corsair SP120 fans.
Just with this radiator alone I'm able to cool a EVGA GTX 670 SC+ as well as an Intel Core i5 3570k and temps are roughly hitting a max of 20-25 degrees above ambient at 1000-1500rpms fan speed.
As I've only had the radiator a short time I can't speak to it's performance over a long period of time but thus far it's made me a believer.
What really sets it over the top for me (past it's stunning watercooling performance) was the superior craftsmanship that is displayed when you first take it out of the box, no flat black easily chipped paint job going on with this - also it comes with pure copper caps as well as copper alan machined bolts for not one but two fans (or one fan and rad mounting).
