Corsair H100 Review

At A Glance


Quiet; excellent performance; easy install; supports up to four fans.


Wont fit in every case; need to open case to adjust fan speed; expensive.

Double your radiator space, double your fun

ANOTHER ALL-IN-ONE liquid-cooling loop! Hooray! Corsair’s H100 is its fifth liquid cooler; after two with Asetek, the company has put out three with CoolIT. The H60 is your standard 120mm radiator-with-single-fan, the H80 is the double-thick double-fan version, and the H100, the first Corsair liquid-cooler to support LGA2011, is its first cooler with a 240mm radiator.

The H100’s radiator is around an inch thick and 10.8 inches long and fits in any case that can accommodate a 240mm radiator, though some cases may not have the vertical clearance to mount the fans inside the case. The pump/heat exchange unit is square, and very slightly taller than Asetek’s. It contains four 4-pin PWM headers to control the radiator fans, as well as a connector for Corsair’s Link system control software/hardware combo (sold separately). There’s also a three-speed fan-control button on top of the pump. The pump unit itself has a 3-pin motherboard fan connector and a 2-pin Molex for power. The cooler unit mount is simple; four double-sided thumbscrews mount to the unified backplate, the brackets at the corners of the pump unit slide onto those, and more thumbscrews secure them in place.

The H100’s 240mm radiator supports up to four 12cm fans, and the pump unit

We mounted the radiator to the top panel of our Thermaltake Level 10 GT test bed, with the fans on the inside pushing air through the radiator out of the case. In this configuration, with the H100’s fan speed set to medium, the Corsair cooler lowered our CPU’s burn temperature to 69.2 C—the best of any cooler in our roundup. Even with the fans at their lowest setting, the H100 was a match for the air coolers in the roundup.

Its 240mm radiator won’t fit in every case, and it’s the most expensive in our roundup, but the H100 is a competent, quiet liquid cooler and the best LGA2011 cooler we’ve yet tested.
