DISCONTINUED EFFECTIVE 8-7-07 PRODUCT NEWS & UPDATES   Introduction The H20-120 series liquid cooling kits are configured for performance oriented users and overclockers who wish to maintain a quiet working/playing environment. This series of kits received more industry awards than any other Swiftech product. It is therefore with great pride that we are now introducing the H20-120 PREMIUM edition. The H20-120 "Premium" CPU Liquid Cooling kit takes the H20-120 convenience and performance features to yet another level thanks to the inclusion of our new flagship, the APOGEE water-block, as well as our now classic MCB120 "Radbox". Performance improvement from the Apogee water-block alone ranges from 2.4 to 3°C as demonstrated HERE. Features & benefits EXTREME PERFORMANCE Features SILENT COMPUTING Features Capturing the heat Our new flagship APOGEE water-block features a quantum leap in performance compared to the MCW6000 series of water-blocks, as shown HERE. Its low flow restriction characteristics also allow daisy-chaining of multiple water-blocks, while retaining rock-solid performance. Adjustable fan speed: fan speed can be adjusted thanks to the included 12v to 7v and 12v to 5v fan connector adapters, allowing users to reduce acoustic noise as follows: at 7v, whisper quiet operations of 24 dBA, and at 5v a barely audible 19 dBA rating. Moving the Heat around High-pressure MCP350 12 Volts DC industrial pump provides ample headroom to daisy-chain additional water-blocks. For instance, the H20-120 Premium will easily support a dual core CPU (AMD® Athlon X2 for example) as well as (2) high-end VGA cards such as nVidia® GeForce 7800 series. 3/8" (ID) tubing offers low restriction with reasonable outside bulk (1/2" OD) Quiet pump operations: 24 to 26 dbA thanks to the brushless motor Dissipating the heat into the atmosphere High thermal dissipation is achieved with a single MCR120-QP 120 mm copper fins radiator featuring a 120x25mm fan selected for low to moderate noise (34dBA) and high back pressure. The MCB120 "Radbox" Revision 2 optimizes cooling by using fresh air from outside the computer, without adding any thermal load to other components. The MCR120-QP radiator fin density has been optimized to reduce air noise and operate at high efficiency with low-flow fans At the lowest fan speed settings, the H20-120 Premium kit delivers low temperatures while allowing substantial overclocks. Convenience & reliability features The MCW-Micro Reservoir ships with universal brackets allowing installation in almost any system and reduces maintenance: the time between coolant refills is approximately 18 months. The MCP350 12v industrial pump plugs into the power supply and features an RPM sensor allowing monitoring of the pump operations by the motherboard. High-reliability, no-maintenance MCP350 industrial pump is rated at 50,000 hour MTBF(Mean Time Between Failures) equivalent to 5 year lifetime. 120mm slim form factor radiator fits into most chassis equipped with at least one 120mm opening for fan intake or exhaust, and can also be installed externally to the back of any chassis featuring at least one 60, 80 or 92mm exhaust fan, by using our patent pending MCB120 "Radbox" included with the kit. The MCB-120 "Radbox" provides a bolt-on mechanism to "hang" the radiator at the back of the case with no case modifications SmartCoils completely eliminate flattening of the tubes over time, and enable users to bend soft vinyl tubing at extremely sharp radii without kinking.   Back to top Performance and comparative data Water-cooling Kit performance testing was conducted in an environmental chamber where the radiator fan inlet air temperature was held at 25°C ±0.1. An industry standard heat die was used as a heat source. Kit Model Radiator/Fan configuration * Heat load Watts** Earlier release Rev 3a °C/W*** New release Premium edition °C/W*** Fan Noise, dBA (per specs, and est.****) H20-120™ Radiator/fan at 12V 100 Watts .160 .134 34 H20-120™ Radiator/fan at 7v 100 Watts .181 .157 24 H20-120™ Radiator/fan at 5v 100 Watts .209 .179 19 It can be seen above that the H20-120 Premium benefits from a 2.4 to 3.0°C drop in CPU temperature at 100 Watts compared to the Rev 3a release. It should also be noted that such difference will further increase (better performance of the new vs. the old) with higher heat loads resulting from extreme overclocking.

FAQ: What CPU temperature can I expect in my own system ? In order to project what your CPU temperature will be, you need to know the following: Power rating in Watts of your CPU. Ambient Temperature inside the computer. For example, if your CPU is rated by the manufacturer at 100 Watts, and the temperature measured inside your computer (close to the fans inlet), is 25°C, then you multiply 100 Watts by our C/W rating of 0.134 (at 12 Volt) = 13.4°C, to which you add the temperature inside the computer of 25°C, = a CPU temperature of 38.4°C at full load. Back to top Processor and Motherboard compatibility The H20-120 Premium kit is is essentially meant as a universal product. It ships with all the necessary hardware for the following processor (classified by the type of sockets that they use): Socket 478 (Intel® Pentium® 4), Socket 775 (Pentium® 4 "Prescott", Pentium® D), Socket 603/604 (Intel® Xeon™ - 400 and 533 FSB) Socket 604 Intel® Xeon™ "Nocona" 800 Mhz FSB - see note 1 below Socket 462 (AMD® Athlon®, Duron®, MP, XP) - see note 2 below Socket 754, 939, 940 (AMD® 64 bit processors). Socket AM2 Note 1: Dual processor users: Since the H20-120 Premium kit is provided with one water-block only, you will need to procure another Apogee water-block for your second processor. The "Nocona" hardware is not included with the Apogee water-block when sold separately, and it should also be procured separately under part number: AP-NC604 ($3.00) Note 2: AMD® socket 462 (socket A). The Apogee can be used exclusively with motherboards featuring the 4 mounting holes around the socket. Removal of the motherboard is necessary to install the mounting posts in all cases, except with AMD® Athlon™ 64 and Opteron™ (socket 754, 939 and 940). back to top Add-on components Liquid Cool your high-end SLI VGA with the MCW60™ VGA cooler Cool the graphics memory with our MC14 Ramsinks Or with the MCWRamcool VGA Memory Water-block Cool the Chipset with our MCX159-CU chipset cooler Or liquid Cool the Chipset with our MCW30 chipset water-block Add a second APOGEE water block for multiprocessor applications, such as dual AMD®, dual Xeon™, or dual Opteron™ Add a second MCR120-QP radiator for a performance gain of 4°C (@ 100 Watts). back to top Example of installation with "Radbox" back to top Individual component specifications Links APOGEE CPU water-block MCRes Micro reservoir MCR120-QP 120mm Radiator MCB120 "Radbox" Rev. 2 Manufacturer Suggested Retail Pricing Part # Processor compatibility MSRP US $ H20-120-PREMIUM Complete CPU liquid kit for Intel socket 478 (Intel® Pentium® 4), socket 775 (Pentium® 4 "Prescott", Pentium D), socket 603-604 (Intel® Xeon™ including"Nocona" class processors), socket 462 (AMD® Athlon®, Duron®, XP, MP) with motherboard mounting holes, socket 754, 939, 940 (AMD® 64 bit Athlon 64, X2, Sempron, Opteron processors), socket AM2 $199.95 Please consult your Swiftech distributor prior to ordering direct from us, or purchase the product factory direct here Back to top
