Introduction The H20-220 Ultima XT CPU liquid cooling kit continues our long established tradition of bundling our top performing components to produce the best cooling kit the market has to offer. A declination of this kit for complete system cooling is also available under the part number Ultima XT Plus. Featuring what many consider as the world's best water-block: the recently released Apogee XT, the MCRES-Micro Revision 2 , the classic MCP655-B pump and MCR220 dual 120mm radiator, the Ultima XT receives yet another quantum boost in both performance and versatility. As a result of the substantial cooling headroom afforded by this combination of top performance components the Ultima XT kit will satisfy both extremes of the enthusiast market spectrum: Overclockers in search of the lowest CPU temperatures AND Silent computing users in search of the lowest possible operating noise. Whereas an increasing number of cases can now accommodate dual 120mm radiators internally, users convenience was not forgotten, and the Ultima XT is shipped standard with our MCB120 "Radbox" Revision 2 which allows the radiator to be bolted-on at the back of practically any mid-or full tower cases. Overall thermal performance also clearly benefits from the use of our Radbox, as explained HERE, and demonstrated in a number of FIELD TESTS . The MCR220 dual 120mm radiator fits nicely at the back of any mid-tower chassis thanks to the MCB120 "Radbox" Revision2 . Platform Compatibility All Intel® Core™ Desktop processor family (Core™2, Quad, Duo, Extreme, i5, i7) in socket 775, 1156 and 1366 form factor. Intel® Server processor family (Xeon™) in socket 603, 604 and 771 form factors (free hold-down plate sent factory-direct on demand worldwide - see details here) AMD® processors in their respective socket form factors - 754, 939, F, AM2 and AM3 (free hold-down plate sent factory-direct on demand worldwide - see details here) Features and benefits EXTREME PERFORMANCE Features SILENT COMPUTING Features Capturing the heat The world's most advanced Apogee XT water-block is responsible for absorbing the heat generated by today's hottest CPU's with incredible efficiency. Adjustable fan speed: the kit is delivered with 12V to 7V and 12V to 5V fan adapters, enabling users to reduce the fan speed -and noise, to whisper quiet operations (~25 dBA). Moving the Heat around The Extreme performance MCP655-B 12 Volts DC industrial pump pushes the coolant throughout the circuit at high velocity. Larger 7/16" ID (5/8" OD) tubing is used to maximize the coolant flow rate inside the system. Dissipating the heat into the atmosphere Minimum toll on performance in "silent" mode The MCR-220 copper and brass radiator doubles the surface area available for heat convection into the air compared to a single 120mm radiator, and uses two 72 CFM 120mm fans, at a reasonable* sound noise level of 37 dBA. The MCB120 "Radbox" Revision 2 optimizes cooling by using fresh air from outside the computer, without adding any thermal load to other components. The MCR-220 radiator fin density is optimized to reduce air noise and operate at high efficiency with low-flow fans At the lowest fan speed settings, the Ultima kit still delivers superb performance while allowing substantial overclocking. For example, at 100 Watts, the CPU temperature is only 3°c higher than at the highest fan settings Convenience and reliability features Kit noise/performance ratio can be fine-tuned at the user leisure. The 12 Volt DC MCP655-B pump plugs directly into computer power supply. High-reliability, no-maintenance industrial pump is rated at 50,000 hour MTBF(Mean Time Between Failure) equivalent to 5 year lifetime. The MCRES-Micro Revision 2 reservoir fits in any small space available in the system without sacrificing a CD-drive bay and can provides up to 18 month of continuous operations without refills. An additional fill-port adds in installation versatility by offering users multiple tube routing options and elaborate mounting brackets allow installation just about anywhere in the PC. Optional remote fill-ports are also available to further enhance the versatility of the installation. The Apogee XT water-block is compatible with all current Intel desktop processors. The MCR-220 radiator is completely self-bleeding in upright position, or when installed on it's side. SmartCoils 625 are included with the kit, to completely eliminate tube kinking for a safe and reliable installation. The 7/16" ID tubing features the same or better flexibility than 3/8" ID tubing, no distinguishable difference in terms of system flow rate compared to 1/2" ID tubing, but significantly reduces the bulk associated with 1/2" ID thick wall tubing. The MCB-120 "Radbox" Revision 2 provides a bolt-on mechanism to "hang" the radiator at the back of the case with minimum case modifications. *For reference, stock cooling solutions for current high-end CPU's are specified by manufacturers between 34 and 38 dBA.
