The Corsair H100 is considerably different than the first kit the company released well over 2 years ago, the well known H50 unit. Clearly Corsair makes these coolers in collaboration with Asetek but the H100 features a new and considerably larger square base, as well as a dual fan parallel liquid flow radiator. The company kept the old but effective corrugated tubing, which is not very flexible but is reliable and exceptionally hard to puncture.
The H100 features a dual fan parallel liquid flow aluminum radiator. The radiator is lightweight and relatively thin but is a proven and cheap to manufacture design which should perform very well. Like all similar radiator designs from Asetek, the very thin and flimsy aluminum fins are extremely easy to bend.
Corsair had to enlarge the base of the H100 in order to house every component they wanted to install inside it. The base houses the liquid pump and of course the thermal absorption plate. The liquid tubes are attached onto the base by using metallic 90° fittings. The wire leaving the base of the cooler splits in two, one to be connected to a Molex connector for power and one to be connected on the motherboard’s CPU fan header for monitoring the speed of the pump. At the center of the top side there is a button which controls the speed of the fans.
The connector seen in the above picture is for connection to the “Link Commander” unit, which Corsair sells separately. This unit can monitor the speed of the fans, the coolant temperature and other parameters. It can also be used to customize the performance profiles of the H100.
At the opposite side of the base Corsair placed four fan connectors. The speed of the fans connected to these connectors is controlled by the H100 itself.
The thermal absorption plate is simple and not particularly smooth. It could certainly be polished better but Corsair has pre-applied a long term thermal compound which is very thick, therefore a better polished plate would hardly make any difference. The plate is held into place with eight hex screws.
