Designed in the USA One or more Patents Pending ROHS compliant Introduction The patent pending MCR Drive™ series of heat exchangers represent yet another world-first innovation from Swiftech®. For many years, it has been our goal to integrate and combine several elements of a standard liquid cooling system in order to save space and reduce cost of ownership while preserving performance and enhancing functionality...read the full product introduction. At the time of release, the MCR Drive™ heat exchangers are available in two versions: dual 120mm, and triple 120mm. The pump used in this application is the MCP350, probably one of the most sold PC pumps in the market today. The heat exchangers are the MCR220-QP and MCR320-QP, also two of the most commonly used radiators in the DIY enthusiast community because of their exceptional noise/performance and price/performance ratios. Exploded view - click to enlarge The MCR Drive™ units are sold in two configurations: Without a pump, to allow owners of MCP350, and MCP355 to install their existing pump to the radiator. With the Apogee™ Drive pump, which is an MCP350 pump with a "footless" body. Features and Benefits High performance Features Benefits - The dual or triple 120mm radiator form factors provide 2 to 3 times the heat dissipation capacity afforded by the single 120mm radiators found in entry level kits. Superior performance headroom Substantially reduced operating temperatures Ability to daisy-chain multiple water-blocks in the loop with reduced impact on CPU cooling performance Higher overclocks - The high-pressure MCP350 pump allows higher system flow rates than comparably sized pumps found in entry level kits, allowing users to daisy-chain multiple water-blocks in the loop. - Integration of the pump into the radiator reduces the overall system pressure drop compared to conventional setups. Convenience Features Benefits - The patent pending integrated pump and built-in reservoir of the MCR Drive™ heat exchanger combine 3 of the 4 typical elements found in conventional CPU liquid cooling systems. Easier to integrate in any PC Simplified installation Safer, more reliable operations (less joints) - Only the water-block(s) will need to be changed in case of platform upgrade. Future-proof concept reduces the cost of ownership over the long term, and guarantees that the core cooling system can be migrated from one computer to another. - Extreme users can easily setup a dedicated VGA loop or install a second unit in series for dual pump dual radiator action! Tame these hot GPU's in SLI, Quad SLI or CrossFire! Performance Performance curves of the radiators and pump are similar to their respective non-integrated counterparts. However, overall system pressure drop is noticeably improved compared to a traditional setup due to a substantial reduction in the length of the flow path, as well as in the number of fittings (2 fittings instead of 6). An additional performance benefit is the new-found ability to run the MCP350 pump with 1/2" lines.
