Even after a company introduces a great and enduring product, the constantly-blowing winds of market demands eventually require a change in tack. When this demand isn't carefully handled, a company risks ruining the very things that made a product successful to begin with. Sometimes drastic changes work, as Apple's radical re-imagining of the iPhone user experience with the iPhone X proves. Sometimes they don't, as with the mixed reception of Apple's radical re-imagining of the 2016 MacBook Pro.

Corsair has arguably been the company most responsible for ushering in the closed-loop liquid-cooled era of enthusiast PC hardware. The H60, H80, and H100, introduced in 2011, likely marked the crossover point where an all-in-one liquid cooler became an enduring and attainable option for enthusiasts versus a monster tower-style air cooler. The company later expanded its lineup with the H105, H110, and a variety of Corsair Link-compatible i-series versions of those coolers, and it sourced those products from Asetek (in GTX guises) and CoolIT Systems (with the GT tag line) alike. I've long used versions of these coolers on my personal systems and test benches alike thanks to their easy-to-use mounting systems, low stress on motherboards, and high performance.
