With the Hydro Series H40, the age of liquid CPU cooling for everybody has arrived. Liquid CPU cooling has traditionally been a potentially messy experience and priced to make sense only for highly over clocked systems. The fact is that liquid CPU cooling is a good idea for just about every PC - it can improve reliability and extend the life of your processor. Hydro Series liquid CPU coolers are closed-loop, maintenance free solutions that install in just a few minutes. Liquid cooling efficiency and a custom-designed fan ensure operation that's both cooler and quieter than most stock CPU fans. The small form factor and flexible tubing allow the Hydro Series H40 to fit in most PC gaming systems. It works with most modern AMD and Intel sockets.
