Introduction
The MCR320-QP (Quiet Power™) is an extreme-duty liquid-to-air heat exchanger designed to be used with three 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 MCR320 -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.
Single and dual 120mm versions of the MCR320-QP
are also available.
Features and Benefits
Installation with a minimum of case modifications
The MCR320-QP can be installed using Swiftech's MCB120 "Radbox". |

|
The MCR320-QP shows a 50% higher heat dissipation capacity than that of the MCR220-QP. Under the test conditions this indicates that the MCR320 can dissipate in excess of 400 Watts while maintaining a 10°C temperature differential between the coolant and the ambient air. |

The improvement is of the order of 1°C per 100 Watts dissipated across the range of tested flow rates. |

 As tested
* Fan noise estimate
based on: "If the speed of a fan is reduced
by 20%, the decibel level will reduce by 5 dB.",
and "addition of a second equal source increases
the sound level by ~3dBA". |

Designed in the USA
Triple 120mm fan form factor triple the surface area
available for convection of the heat into the air
compared to single 120mm fan designs. The Quiet Power
design yields superior performance at low noise levels compared to competing
products in the same class.)
