Corsair's Hydro Series H50 has been popular for those looking to test the liquid-cooled waters, so to speak. Its prefilled, closed-loop configuration, good performance, ease of installation, and affordable price appealed to a broad swath of users. With the new Hydro Series H70, Corsair aims to improve upon the H50 in a few key areas while maintaining the appealing aspects of the original. Like the H50, the H70 is a prefilled, closed-loop liquid-cooler, compatible with Intel's and AMD's modern desktop processor sockets. The H70, however, features a thicker radiator with more surface area than the H50, dual fans arranged in a push-pull configuration, and an improved copper cold plate/ pump assembly. The end result is a cooler that's as easy to install as the H50, but with a superior ability to dissipate heat.
The H70 includes similar mounting plates, so the installation process is about the same as the H50's. The radiator and fan assembly attach to an available rear 120mm fan mount. And after installing the necessary retention plate for the particular socket, the cold plate/pump assembly is screwed down securely. I tested the Corsair H70 (with its fans running at full speed) with a Core i7-975 at stock and overclocked (4GHz) speeds. The H70 decimated the i7-975's stock cooler. The Corsair Hydro Series H70 is a top-notch kit in almost every way, but the improvements over the H50 come at a price. The H70 will sell for about $110, putting a bigger dent in your budget than the H50. Still, we suspect enthusiasts who opt for the H70 will ultimately be pleased by its performance ..•
