DISCONTINUED PRODUCT NEWS & UPDATES   Introduction The Apex "Ultra" model is an upgrade from the Apex initial release differentiating itself by the use of our new flagship Apogee GT water-block. The Apex Ultra liquid cooling kit is the first kit in the industry to offer truly extreme dual use: maximum performance and minimum noise in the same package. Thanks to the new Apogee GT water-block, it benefits from a superior thermal performance and very low restriction characteristics. This makes the Apex Ultra a true high-flow system, capable of cooling multiple high-end CPU's and VGA's with optimum thermal performance and low noise as demonstrated HERE . NEW! Effective 2-20-06 the H20-220 Apex Ultra is now also available in a complete system cooling solution thanks to the inclusion of the MCW60 VGA kit and the MCW30 Chipset water-block. The kit receives the part # H20-220-Apex Ultra+ - See pictures and pricing here - all other specifications remain as described below. As a result of the substantial cooling headroom afforded by the combination of our new MCR220-QP dual 120mm radiator, the Apogee GT water-block, and the MCP655-B pump, the APEX Ultra 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. Sacrificing user convenience was not an acceptable option when we developed this kit either. Given its size, the MCR220 dual 120mm radiator will not fit in most PC's without extensive modifications. While many of our enthusiast users do not mind using the dremel tool, we are happy to report to the less mechanically-inclined users that they have not be forgotten. The H20-Apex kit is shipped standard with our MCB120 "Radbox" Revision 2 which allows the radiator to be installed at the back of practically any mid-or full tower cases with no other modifications than a couple of holes. Overall thermal performance also clearly benefits from the use of our Radbox, as explained HERE, and demonstrated in a number of FIELD TESTS . The massive MCR220 dual 120mm radiator fits nicely at the back of any mid-tower chassis thanks to the MCB120 "Radbox" Revision2 . Fan guards have been added to afford protection to the radiator's delicate fins. In this installation, which includes a VGA cooler the inside of the computer remains relatively uncluttered, and none of the CD or hard drive bays are sacrificed. Features and benefits EXTREME PERFORMANCE Features SILENT COMPUTING Features Capturing the heat The extreme performance Apogee GT Universal 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 new 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 has been optimized to reduce air noise and operate at high efficiency with low-flow fans At the lowest fan speed settings, the H20-APEX 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. 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. MCRES-Micro reservoir fits in any small space available in the system without sacrificing a CD-drive bay MCRES-Micro reservoir provides approximately 18 month of continuous operations without refills. Universal Apogee GT water-block is compatible with all current desktop processors, and ships with all the different mounting systems. The Patent pending 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.
