Antec Demos Kühler H2O 1250 and Kühler H2O 650
Antec is showing off two new coolers at Computex, the Kühler H2O 1250 and Kühler H2O 65. Both of the coolers feature a new concept for liquid cooling -- quite an interesting concept. The fan's motor hubs also work as the coolant pumps, meaning that there is only a single moving part (or two in the case of the 240 mm H20 1250) in the devices. This also means that the flow of the coolant is in direct proportion to the fan speed, so a higher fan speed directly translates to a higher coolant flow.
With fewer moving parts, we'd imagine the device is more silent; however, a lot more power will be required from a single motor to do the two tasks. Moreover, the unit's fans will not be replaceable, nor will the orientation be switchable; it can only be used in a push configuration.
The units will be compatible with all of the most recent CPU sockets, including LGA1150. The company gave no word on pricing or availability, but we can likely expect some price premium over competing units.
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.
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
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.
