H20-220™ (REV. 2) SERIES LIQUID COOLING KITS H20-220-P Introduction The H20-220™series liquid cooling kits are designed for quiet operations in extreme thermal load environments such as multiprocessors, thermoelectric applications, or extreme overclocking. These kits are ideally suited for wide body server chassis featuring 120mm fan ventilation. A chassis modification is required in most cases to locate the dual 120mm radiator. Other components are entirely plug-and-play. The kits' performance, and convenience factors are now enhanced compared to the original series models. This is due to the replacement of the fill-and-bleed kit, by our new MCRES-525 5 1/4" drive bay reservoir, which yields a better overall system flow rate. Reliability of the kits is guaranteed by the MCP650™ pump featuring a 5 year lifetime. Performance features: Extreme performance MCW6000™ series waterblocks Extreme performance MCP650™ 12 Volts DC industrial pump 1/2" OD tubing for optimum flow rate, and reasonable bulk Slim profile radiator assembly with dual 120mm fan, each rated at 72 CFM (34dBA) each. Radiator may be installed outside the case. 5 Watt 25 Ohm Rheostat, allowing to adjust the fans voltage to fine tune airflow and noise levels. Convenience features: 12 Volt DC pump plugs directly into computer power supply. High-reliability, no-maintenance industrial pump features quiet operations thanks to brushless motor, and is rated at 50,000 hour MTBF(Mean Time Between Failures) equivalent to 5 year lifetime. MCRES-525™ 5 1/4" Drive bay reservoir allows a quick and easy procedure for filling-up the system Pre-installed tubing on the water-block and pump, and quick-connect fittings on the radiator reduce installation time. Plug-and-play waterblock installation, doesn't require removing the motherboard (most models). Coolsleeves™ coils completely eliminate flattening of the tubes over time, and enable users to bend soft vinyl tubing at extremely sharp radii without kinking. Optional devices and configurations: Add a VGA cooler such as the MCW50™ Add a chipset cooler such as the MCW20™ Add a second water block for multiprocessor applications, such as dual AMD®, dual Xeon™, or dual Opteron™. Kit configurations & Models: Page 2   back to top Performance Data Water-cooling Kit performance testing was conducted in an environmental chamber where the radiator fan inlet air temperature was held at 25.00°C ±0.05. As a heat source, in place of a CPU, a heat die simulator was installed in a bare chassis with the actual kit pieces.

A custom gasket is provided with the assembly  to optimize the seal between heat-exchanger, panel, and fans. The inlet and outlet tube diameter are 3/8", and factory equipped with 1/2" quick-connect elbow fittings. Rubber grommets are provided for routing the tubing inside the case.
