It looks nice, however from their own provided cooling graphs it seems to be about the same, if a bit worse than their old waterblocks (which weren't that great). I am baffled they wouldn't have come up with something that cools better. Basically they seem to have prettied up their blocks and done nothing else.
I have a friend at Polarflo and I will be emailing him today to get one of the CPU blocks to test and review - but from the looks of the new base design, I can't see it performing better than previous blocks, and I am afraid it will not be competitive with the others out there, such as the TDX, Apogee, and Storm.
