Antec Kühler H2O 1250 and 650 Innovate with Fans
Antec unveiled a pair of new all-in-one CPU coolers in the Kühler H2O series, the Kühler H2O 1250 and Kühler H2O 650 (pictured in that order). The two build over their Series 4 predecessors with more powerful pumps, and new high-airflow fans that focus airflow through the radiator. The fan's motor doubles up as the pump's, and so the air and coolant flow are in perfect proportion. The H2O 650 features a 120 x 120 size radiator with a single fan, while the H2O 1250 doubles the dissipation area with a larger 240 x 120 radiator, that uses two of those fans. The two ship with support for the latest CPU socket types, including LGA115x, LGA1366, LGA2011, AM3+/AM3, and FM2/FM1.

If the fan goes, then what?
But who knows!
Thing that worries me is that pump might have to get loud to produce flow fast enough for fan to actually push some air.
But yes if fan goes so does pump but that could happen with older units that had it biult into block.
The pluses I see is "could" be better flow as pumps are not constricted to the small water block like before and you get 2 pumps with the 240mm .
The big downside i see is on the 240mm since the fan and rad are one piece as far as I can see as you have water hoses connecting them .your going to have hard time with fitment in top with MB .both will have to be internal .
Last if you let dust build up , well that would slow fan and pump .so you need to keep it clean and of course you can't update fans, only thing you could maybe do if you have space is add fan for push/pull config .
Maybe this is a revolutionary design because the heat of the pump is not more concentrated over the waterblock this can save some degrees.
Other than they save in the one cost effective generic fan/motor... just to add complexity to what is a seal for the output shaft of the fan? Most pumps are floating mag-drive "seal-less" impellers. Now they have a dynamic seal interface to the fan that can leak! I see no advantages to this for Antec or the user. If the fan/pump motor noise then they warranty the whole thing. I wouldn't want to be without the whole computer, while this gets RMA'd when it just a noisy fan they can send to me.
Certainly won't expect it to win any performance awards.
We need more info and reviews .
I could say the opposite infact as pump is not forced to fit and be confined to the block .
as to more leaks does custom which has separate pump and other components is considered worse ?
we don't know how these pumps work ,especially the dual pump versions .
I would never buy this myself but might be good for something like OEM depending if it works good .
