The MCR220-QP (Quiet Power) series are extreme-duty liquid-to-air heat exchangers designed to be used with dual 120mm fans, and specifically engineered for high-end liquid cooled Personal Computers.
They are 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 MCR220-QP Stackable radiator uses the "classic" body of the MCR220 series, the upper features two inlet and outlet ports opposite to each other, thus allowing to stack radiators together.
This is the perfect upgrade for existing owners of MCR220-QP radiators in search of Extreme performance...
