i would like to see some reviews on this, i would like to think it would be quieter but given the fact that there cant be a lot of coolant in those pipes the fans must be working pretty hard to keep it cool

They better put some damn good fans on.

It's an interesting first pass, but with the inability to operate in push/pull, I'd be curious to see how these things perform.
Because of the knobs, they take up almost the same width as something like the H100. I'm not sure placing the pump on the fans is the best idea either since you can't swap out the fans.

they could've easily made the fans interchangeable had they keyed/sleeved the connection from fan to pump

Is it just me or can you not just put another fan on the OTHER side that pulls and then you have a push/pull config?

cool idea but i see some problems. pumps on these sealed water coolers normal spin MUCH faster than the fans do (I think the pump on the corsair H60/80 coolers spin at something like 2500RPM)
second of all is what if i want to use different fans? like lets say Scythe Gentle Typhoons or Noctua fans? and i hope antec put good bearings in those fans because if they fail they are attached to the pump and cant be replaced where as on other coolers you can change the fans out. as quoted from the article

"Moreover, the unit's fans will not be replaceable, nor will the orientation be switchable; it can only be used in a push configuration."
cool idea (no pun intended) but I am not sure how good these are and how long they will last

Much better design now! Pump itself usually generates heat. I would suspect that two fans would produce more noise than one in pumping. And then there is one "what if". If one fan is slower than the other one, this would mean more stress on pump pumping faster, which generates more pressure in tubes.... and we have a leakage case!

With a properly designed fan, there would be no need for push-pull.

The biggest problem with slim fans is they lack a proper shroud/cowling with tight enough tolerances to maximize the fan's potential. Make the frame twice as thick with a shape optimized to convert centrifugal and rotational forces into forward motion (most fans have a convex inner frame wall with half or more of the blade thickness on the 'wrong' side so a lot of air spills back out the intake side along the edge), add static blades to convert air rotation into forward movement/static pressure and you can get most of the air-pushing power of two slim fans with roughly half the total power.

Wonder if the Kühler H2O 1250 will fit in a Corsair Graphite 600T?
