I just got the new Swifty CPU WB that has 1 inlet and 3 outlets. Two of course are optional and to really use it you'd need watered cards, chipset, and ram since it's designed to run a parallel flow to all components and then loop everything back with the new swifty rad with 3 inlets and one outlet.
I bought it cause it's BLACK, and should look cool on my R3EBE
Seriously, it's supposed to be less restrictive and more efficient than the swifty XT it replaces as the flagship. I always thought the XT was a piece of shit, so hope i didn't screw up again
EK Supreme has had some very positive reviews. For MASS, the Kryos HF full copper block is probably the biggest I've had but reviews just below the EK. Also, the Kryos mounting hardware ain't for shit.
