The Corsair H100 was the best CPU cooler we’ve seen to date. With its 240 mm radiator, which is twice the size of the radiator seen in most sealed liquid cooling systems, it outperformed all the air coolers and liquid cooling solutions we tested so far.
However, it is not perfect. Its main drawback is that it will fit only mid-tower cases that support a 240 mm radiator on the top panel. However, the H100 may not fit full-tower cases, because the hoses are relatively short and the radiator must be near the CPU block. Another problem is that it is not quiet at all. Even in the silent mode, the fans were louder than they should be.
Nonetheless, we are talking about a CPU liquid cooling solution with the highest cooling performance we have seen so far, which means it is designed for power users who want to keep their CPUs as cold as possible with a single, easy-to-install, cooling solution.
