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.

Fail. That is all. So the fan spins with the flow of fluid.
If the fan goes, then what?

Seems to complicate things by loads, with negligible benefit.

But who knows!

Well then lets hope warranty is like 6 years. :laugh:
Thing that worries me is that pump might have to get loud to produce flow fast enough for fan to actually push some air.

For one we need more info on specs of pump/fan rpm and flow .
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 .

Basically you cant change the fan but the all system also gains thikness without being more efficent cooling.

Maybe this is a revolutionary design because the heat of the pump is not more concentrated over the waterblock this can save some degrees.

Interesting idea I am curious for reviews to see how well it works. From size I would say the pumps cannot be that powerful.

That does seem complicated for nothing indeed. This kind of design would only greatly lower cost since there is only 1 motor for everything.

I could be wrong on this, but this press release blurb isn't shoring up the argument for it being smarter. Not saying it can’t work correctly up to a particular TDP CPU’s, but I can't figure why thinking offering less control is smarter. Why in any right thinking brain would you not want independent controls for both pump output and fan CFM/noise... I can't think someone in engineering thought this was smart? Marketing I can see them thinking "this differentiates us in the market" cool...

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.

The design is a horrible idea as it increases the chance of a catastrophic failure. More stress on the pump, more places for leaks, more resistance to flow. No thanks.

Agree, agree and agree, but the price should be so low, it's probably shouldn't be compared to mid-range watercooling, but to mid-range air cooling. Should win as far as price goes.

Certainly won't expect it to win any performance awards.

I would imagine this setup would be quieter than others as it keeps pump noise and fan noise down , of course it still has to cool .

We need more info and reviews .

While I don't think it good idea for top mounted or even back as your stuck with fan . I don't see how you can says it increases catastrophic failure w/o more info .
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 .

Ok, I looked at this again and the fluid flow make no sense on the single unit. It’s like the radiator is divided in the middle? Water goes in/out the CPU block, but both lines goes to the same bottom radiator tank. Both lines exit the top tank and go to the pump? To make a loop heated fluid from the CPU block to the bottom; but the tanks/core has to be separated. Cooled partially in one half; out the top then through the pump. Output from the pump through the other half of the radiator to the bottom where it dissipates the final bit, before returning to the CPU block. :confused:

your right ,normally one end has a divider ,but because of where pump is and how its setup, this has divider on both ends .
