Swiftech MCR240-QP "Quiet Power" Radiator 280, 140mm x 2, Dual Fan

The MCRx40-QP (Quiet PowerTM) series radiators are heavy-duty, low-noise optimized, liquid-to-air heat exchangers designed to be used with 140mm fans and specifically engineered for high-end liquid cooled Personal Computers. First introduced in 2005, the Quiet PowerTM 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. To this day, the Quiet Power radiators have set a standard for others to follow, and meet today's PC industry highest thermal loads, quality standards, and low noise requirements at competitive prices. For a good noise to performance ratio we recommend using the MCRx40 series radiators with fans rated in the 1500 RPM range or below (higher RPM ranges may be used for louder results).
