Antec Kuhler h2o 1250 Cooler Review

The Conclusion:

At first I didn’t think the Antec Kuhler 1250 was doing it’s job. In my test setup, It only outperformed the NZXT Kraken x40 by a small margin. The Kuhler 1250 has a Rad surface area of 28,800sq/mm versus the NZXT Kraken x40 surface area of 19,600sq/mm (47% more area) so, it should have done better. But, then, I decided to give it another shot. I put the 1250 in my little Bitfenix Prodigy as a top exhaust setup and it excelled. It dropped an additional 15 degrees off of it’s previous best performance. Even though it can only be used in an exhaust setup (single direction fan/pumps). So plan on using it on the top of your case. Since, not many cases have room for dual 120mm fans in the back. Although, putting it in the top seems to work well with the semi-frameless fans. Clearance problems are reduced by having the Pump/fan motor be the thickest part, away from the Motherboard. However, it’s great performance can’t overcome all of it’s downfalls.


  • Fan frames take up minimal edge space along sides of Rad.
  • Cooling hoses are flexible without worry of them kinking.
  • Mounting hardware allows same brackets for both Intel/AMD.
  • The Antec Kuhler 1250 outperforms most of the AIO Coolers.


  • Integrated fan/pump means it can only be used in exhaust setup.
  • Antec doesn’t disclose this fact in any of their information.
  • The Steel inserts won’t stay in the rear mounting bracket.
  • Lack of a pump in the water block doesn’t make it any smaller.
  • Antec Grid software doesn’t allow a custom fan curve setup.

[center]The MSRP of the Antec Kuhler 1250 is $119.95

( It’s smaller brother, the 650 is only $69.95 )
It’s available now at Newegg.
Because it’s “exhaust only” setup, which isn’t really disclosed, I’d give it a 3 out of 5.

Although, if it’s features matched it’s performance, I would have given it a 5 out of 5 :^)

So, I averaged out my Pros and Cons and came out with a score of 4 out of 5 Nanners.
Final Score: 4 out of 5 Bananas

  1. Hmm, interesting setup. Only having the single set of fans and not being able to run push pull if I wanted is kind of a deal breaker. Thanks Greg for the review.

  2. Great review man! I also want to know if the fans can be setup as Push/Pull. Everything else looks good, other than those fans. I really don’t like the way they look lol. I mean it would be different if they worked real cooling miracles, but other than that, they look like the radiator’s boobs. By the way, I really like that you tested it in different cases!
