H20-80™ REV. 2 SERIES LIQUID COOLING KITS H20-80-P™ Introduction The H20-80™ revision 2 series liquid cooling kits continue our tradition of plug-and-play and balanced performance vs. noise cooling systems. 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. These kits are specifically intended to bring the efficiency, and quiet operations of liquid cooling to confined environments. They require no case modifications, and may be installed with all existing components already in place inside the chassis (*) The H20-80™ series kits include a number of options to accommodate most configurations, from mild to extreme cooling, and they are ideally suited for any chassis featuring 80mm fan intake and/or exhaust openings. Performance features: Extreme performance MCW6000™ series water-blocks Extreme performance MCP650™ 12 Volts DC industrial pump 1/2" OD tubing for optimum flow rate, and reasonable bulk Good balance for performance versus noise is achieved with a single MCR80-F2 80mm copper-core radiator featuring an 80x25mm fan optimized for low noise (28dBA) and high back pressure. Extreme performance can be achieved by adding a second MCR80-F2 for a gain of up approximately 4°C. Convenience & reliability 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 80mm form factor radiator fits into any chassis featuring at least one 80mm opening for fan intake or exhaust 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™. Add a second radiator for a performance gain of up to 4°C at equal heat load. Note: this option is always recommended in dual processor configurations Kit configurations & Models: Page 2 Examples of installation on an AMD® K7 platform. Picture 1 includes an MCW6000-A™ CPU cooler, MCW20-A™ chipset cooler, and MCW50 VGA™ cooler, and picture 2 is the same setup with an extra MCR80-F2 radiator. Note the tight and "clean" radii that can be achieved with the coolsleeves™ coils.

The thermal resistance of the system could then be characterized by the difference between the fan's inlet air temperature and the heat die, divided by the heat load in Watts; such ratio is commonly referred to as the "C/W". The results below are accurate and comparable as the only variables were the radiators, and fan voltages. Users comparing their or other systems and data are cautioned that such comparability is tightly dependent upon how accurately the heat load (Watts) is characterized.
