CONCLUSION

   Since we're talking about a 240mm radiator we knew right from the start that the KUHLER H2O 1250 would outperform the 950 model even if just by little (since the radiator used with the 950 is quite thicker) but in the end at least in Extreme mode the difference is quite substantial and what really steals the show is that the 1250 managed to get very close to the Raystorm 750 EX280 watercooling kit by XSPC something which we didn't really expect. However it's very clear that it did so at a price and so although the KUHLER H2O 1250 is the 2nd best CPU Cooler in our database right after the Raystorm 750 EX280 it's also the second loudest one and although that may not be enough to drive away serious gamers (since many graphics cards are equally loud when at load) and overclockers it will most certainly drive away some casual gamers and users. Both fans being fixed between the radiator and the pumps is also something that doesn't help things and although we've already mentioned in the past that the 3 years warranty is plenty for such a device and that fans rarely fail still many users would like to know that they can use their own if something goes wrong or if they want something better. The GRID software does a very good job in allowing the user to control the speed of the fans at will (all 4 if you add 2 more in push and pull) and the overall installation is extremely easy so no complains here.

   Much like the 650/950 models the KUHLER H2O 1250 Liquid CPU Cooling System by Antec has price on its side and so currently you can find it for USD119.99 inside the USA (Newegg) and for 97Euros inside the EU (Amazon.co.uk). Of course at around the same price point there are other similar solutions by Corsair and other companies but as far back as i can remember Antec always had the upper hand in terms of performance so if that's what you're after in such a solution and your tower has room for an 240mm radiator then the KUHLER H2O 1250 is the proper choice. Unfortunately however because of its high noise levels and fixed fans it just marginally missed receiving our Platinum award (not that our Golden Award is bad).
