Swiftech MCR320 Quiet Power 3X120mm Radiator - MCR320-QPK

Introduction

The Swiftech 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

High Performance	Low noise
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.	Optimized for 120mm fans with low to medium air output. The added heat dissipation capacity enables multiple high-end devices (multi-core CPU's, and SLI systems) to run highly overclocked at the lowest possible noise levels.
Flat brass tubes and copper louvered 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 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. Competitive pricing with same class radiators (single row, 2 pass).

Installation with a minimum of case modifications

The MCR320-QP can be installed using Swiftech's MCB120 "Radbox".

Performance Curves - MCR320 triple compared to MCR220 dual 120mm radiator

it can be observed that the pressure drop is marginally higher than that of the MCR220-QP

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.
