Introduction The MCR120-QP (Quiet Power™) series radiators are heavy-duty liquid-to-air heat exchanger designed to be used with 120mm class fans, and specifically engineered for high-end liquid cooled Personal Computers. The Quiet Power™ technology is the result of months of research and development focused on optimizing thermal performance and audible noise characteristics with low to medium airflow types of fans. The MCR120 -QP heat exchangers have been engineered to meet today's PC industry highest thermal loads, quality standards, and low noise requirements at competitive prices. Two form factor versions are available: The MCR120-QP features threaded hubs, compatible with 1/4" NPSM, BSPP, and G1/4 fitting (1/4" thread to 1/4", 3/8 or 1/2" barbs), 3/8" black nylon barb fittings included The MCR120-QP Res features built-in 3/8" barbs, and an integrated reservoir sufficient for years of operations without coolant refills. Dual and Triple 120mm versions are also available here (220), here (220-RES), here (120), and here (320). Features and Benefits High Performance Low noise The new Quiet Power design yields higher performance than previous MCR120 model, and delivers ample heat dissipation headroom for the most demanding applications Optimized for 120mm fans with low to medium output (80 CFM and below) Flat brass tubes and louvered copper fins, with brass plenum chambers and frame construction, for optimum thermal conductivity. Fin density optimized to reduce air noise Flat frame surface provides optimum seal to the fans Built-in plenum chamber Convenience, Reliability, Quality, Competitive price Single 120mm form factor fits in most modern cases equipped with 120mm fan openings. 1/4" NPSM Threaded hubs are compatible with 1/4" BSPP and G1/4 fittings. Patent-pending Self purging plenum chambers design: when installed upright or on its side, air cannot accumulate in the plenum chambers. Threaded fan and case mounting holes for quick and repeated installations. Slim form factor 6.2 x 5 x 1.3" (158 x 128 x 34mm) reduces bulk. No oxidation over time (compared to aluminum radiators). Beautiful and durable gloss acrylic paint finish. Competitive pricing with same class radiators (single row, 2 pass).
