The Corsair COOL Water Cooling Kit includes a high pressure inline centrifugal pump. Built by Delphi the DDC-1P pump gets its 12 volts directly from a Molex connector. It has a 3-pin fan header plug with a tachometer wire so you can monitor the speed of the pump programmatically (via BIOS). The pump is very reliable and requires priming before turning it on. The DDC-1P does accept a range of voltages between 8V and 13V, so you can adjust the speed of the unit if you so desire. Power consumption of this pump in my test rig is 5 watts. Actual tested output of the pump is calculated at 300 Liters Per Hour (LPH) or 78 Gallons Per Hour (GPH). The pump has notches so it can be mounted using screws, bolts or an adhesive neoprene pad (all included). No matter how you choose to mount this pump, use of the neoprene pad is suggested as it effectively dampens noise.

On the active cooling side of things, we have a 120mm fan, a one pass radiator and a “RadBox” mounting system. The fan is 120mm by 38mm, has a voltage range of 8 to 14 volts, and consumes 2.4 watts of power. It spins at 2000 RPM and has a noise rating of 26 dBA. Pushing 60 CFM this fan should be more than adequate to cool a very hot processor. The radiator features a low restriction design to help keep the water moving. It is also very quiet with no audible turbulence within. It has a durable acrylic finish with 4 holes tapped on each side of the radiator. It’s an extremely flexible design, and looks as though it will perform very well. Mounting is accomplished by the “RadBox”. This marvelous piece of engineering allows the fan and radiator assembly to be mounted virtually anywhere on any case. No 120mm fan hole? No problem. No fan holes at all? No Problem. Anyone looking to water cool with the Corsair COOL 120mm will not be disappointed, this kit can be installed on anything!
