Two HG10s, three H75s, one Air 240: The Dual HG10-A1 Build

By Dustin Sklavos, on November 5, 2014

It’s not at all uncommon (in fact, exceedingly normal) for Corsair employees to want to tinker with our latest and greatest products just to see what we can actually do. While I was doing a single HG10-A1 build in the Carbide Series Air 240 that I was pretty proud of, one of our product engineers, Dennis Lee, was pushing things…well, a lot further.

His Air 240 build borders on insane, and I’m happy to share it with you.

Dennis’s build is…pretty wild. He used white SP120 LED fans and a red sleeved cable kit, then doubled down and swapped in LED lit pump caps from H105s onto all of the H75 coolers. The result is easily one of the craziest systems we’ve ever seen and a testament to just how much power can be crammed into a Carbide Series Air 240.

In all of its glory: two liquid-cooled AMD Radeon R9 290X cards on an X79 Micro-ATX board with just about everything under water.

Bird's eye view. In order to fit two H75s in the main chamber, one had to be arranged in a push-pull configuration.

The H75s operate as intakes, keeping the blowers on the HG10s fed while the two top fans work as exhausts.

The pair of HG10s look cramped, but were designed to allow for exactly this kind of close proximity when used with the right Hydro Series cooler.

The third H75 (cooling one of the R9 290X cards) had to be mounted to the 120mm fan mount in the back chamber.

Screw the H75 radiator to the side panel, close it up, and game on.
