Closer Look: Antec Kühler H2O
The Antec Kühler H2O 920 box tells you everything you need to know: it's a CPU cooler, it uses liquid cooling, and it fits these sockets. This seems basic information, but you'd be amazed how often companies make you hunt for this.
The components included are the pump/radiator assembly, two 120mm PWM fans, mounting brackets, a manual, and a driver CD. Wait, a driver CD? For a CPU cooler? Yeah, we'll get to that.
The pump and radiator of the Kühler 920 appear very similar to the Corsair Hydro Series H70: it seems to use the same low-profile pump and double-thick 120mm radiator. But there are some differences.
The differences are these cables coming from the pump. From the left are the power cable, two PWM fan cables, and a USB cable. Wait, a USB cable? It's all part of the software control this cooler sports.
The Kühler mounting system is Asetek-OEM standard: a thin metal retaining ring with interior notches is secured to a back plate by four screws. The pump has notched edges; after mounting the bracket and installing the screws part-way, you insert the pump from the top and rotate it a few degrees so that the notches on the edge of the pump slide under the notches on the inside of the retaining ring. Tightening the screws will clamp the retaining ring against the pump and press it firmly against the processor. You'll actually have to assemble a bespoke bracket from the components included: four metal screw inserts must be positioned in the correct 4 (out of 12) possible places in the Intel back plate, and the retaining ring requires that 4 screws be inserted into the proper plastic offsets, which are then snapped into the retaining ring. All told, 14 different pieces comprise a complete mounting system, and paying attention and assembling the right parts correctly for your application will pay off. A slight difference here is that Antec has molded the screw holders for the Intel bracket in bright blue plastic, while the screw holders for the AMD bracket are molded in green plastic. However, the supplied manual does not call this difference out, so be careful to use the correct screw holders when assembling the bracket.
There's more to the Kühler, as we'll see in the next section.
