Corsair H70: Design And Technical Data
The Corsair H70 prefab liquid cooling system comes in a sturdy cardboard box. In addition to the already-filled, closed loop cooling system consisting of radiator, hoses, and water block with built-in pump, we find detailed installation instructions and mounting hardware for different computer platforms in the package. The Corsair H70 supports Intel's LGA 775, 1366, 1156 interfaces, along with AMD's AM2 and AM3 sockets.
Additionally, the Corsair H70 cooling system includes two fans that operate at 2000 RPM. The included adapter cables with embedded resistors (~30 ohms) can be used to bring the fans down to 1600 RPM for quieter operation. There is no thermal compound included, which most coolers usually do bundle.
Compact Water Block
Instead, Corsair opts to cover the CPU water block base with a layer of thermal compound straight from the factory. This thermal compound is protected by a solid and easily removable plastic cap that is attached to the underside of the water block, protecting it from damage during transport.
Hardcore cooling enthusiasts would likely remove the compound and replace it with a thin layer of something more expensive, but obviously this is not mandatory.
With a height of just two inches, the water block is very compact. The low profile is even more notable when you consider that the pump is integrated with the water block, driving the coolant through the closed loop system. A cable connects the pump and the motherboard, supplying the pump with 12 V power. The pump is extremely quiet; only in a completely silent environment were we able to hear a faint hum.
The coolant travels through the cooling system via two small and relatively rigid tubes. They have an outer diameter of about 8 mm and a length of about 24 cm. The tubes are attached to the pipes in such a secure way that they can only be replaced with great effort. Except for the water block, the loop also includes the radiator. Due to the short length of the cables, you might not be able to install the radiator exactly wherever you want to if you are using a large computer case.
