Product Info

The easy performance upgrade for your Intel CPU

Your PC will run cooler and quieter when you replace your CPU’s standard heatsink with a Hydro Series H55. Installation is straightforward. If you can get to the back of your PC’s motherboard, you can install an H55. All you’ll need is a screwdriver.

Great for smaller cases
The compact components and flexible tubing make H55 easy to install even if you’re cramped for space.
