Maintenance free, cooler & quieter - the Corsair H60.
The Corsair Hydro Series H60 is a fantastic choice for cooling. With a new micro-channel cold plate and a split-flow designed manifold, the H60 brings remarkable new technologies to an affordable price point. If that weren't enough, the H60 also features an all-new fan, custom designed to offer enhanced static pressure, which means better cooling.
You don't have to sacrifice performance to build a quiet system. Most high-performance coolers use crude, outdated designs that rely on two techniques: put a huge hunk of metal in your case or crank the fan to obnoxiously loud noise levels. The Hydro Series coolers feature innovative, cutting-edge designs that utilize the superior thermal conductivity of liquid over air to provide fantastic cooling at much lower noise levels. In fact, the H60 is similar in noise levels to a 120mm case fan you probably already have.
Noise level: 30.2 dBA.
