Corsair Hydro Series H55 Core High-Performance Quiet CPU CoolerYour 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. The compact components and flexible tubing make Hydro Series H55 easy to install even if you're cramped for space. It allows you to improve your CPU's cooling efficiency even in most compact cases - as long as your case has a 120mm fan mount near the CPU, H55 will probably fit.
