The Low Noise Intel CPU Performance Upgrade.

Your PC will run cooler and quieter when you replace your CPU's standard heat-sink with a Hydro Series H55.

The compact components and flexible tubing make Hydro Series H55 easy to install even in smaller computer cases. Hydro Series H55 comes pre-filled, and never needs refilling or priming.

The low speed and wide diameter reduces noise levels over the smaller, faster fans used on stock CPU coolers. The three-pin connector is compatible with fan controllers.

Noise level: 30.32 dBA.
