The MCR220 -QP heat exchangers have been engineered to meet today's PC industry highest thermal loads, quality standards, and low noise requirements at competitive prices.
A single 120mm version of the MCR220-QP is also available here.
Effective April 2007, all MCR220-QP Radiators receive 1/4" NPSM hubs instead of 3/8" NPT hubs. In addition, a performance improvement is also implemented as described in the curves below. Please click HERE to access the performance curves of the MCR220-QP shipped prior to april 2007.
Example on how to read the above curve: In a Swiftech system flowing ~1.0 GPM we observe that with the fans used (*) running at 7v, a 210 Watts load -corresponding to an overclocked/overvolted quad-core Intel processor can be dissipated with a mere 10°C temperature rise of the coolant over ambient air.

* Fan noise estimate based on the following estimations: "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".
