The MCR420-QPK (Quiet Power™) is an extreme-duty liquid-to-air heat exchanger designed to be used with four 120mm 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 MCR420 -QP series heat exchangers have been engineered to meet today's PC industry highest thermal loads, quality standards, and low noise requirements at competitive prices.

1/4" NPSM threaded hubs (BSPP and G1/4 compatible) for maximum compatibility with various tubing installations.
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 design to facilitate installation, and reduce bulk.
No oxidation over time (compared to aluminum radiators).
Beautiful and durable gloss acrylic paint finish.
ROHS compliant
