Swiftech MCR320-XP Radiator

This is the fourth in my series of triple radiators the Swiftech MCR320-XP .  This model is one of two radiator categories by Swiftech which is optimized for medium to high speed fans where the “XP” stands for Xtreme Performance sporting a more dense 20 folds per inch.  Swiftech also has an QP series which looks very much the same, but has a lower density 12 FPI core.  Here we are looking at the more dense XP model designed for medium to high speed fans.

A special thanks to Gabe from Swiftech for providing the review sample:

The MCRx20-XP (eXtreme Performance) series radiators are high-performance liquid-to-air heat exchangers optimized for use with medium speed 120mm fans and specifically engineered in a slim for factor for high-end liquid cooled Personal Computers.

The XP series derive from the Quiet Power technology (QP series) first introduced in 2005 and both series share the exact same dimensions. They differentiate themselves by a higher fin-per-inch (FPI) count where the QP series feature a 12 FPI specification versus 20 FPI for the new XP series. A higher FPI count means that the XP series are more efficient at dissipating heat in the higher RPM fan ranges. When large heat loads are involved for example a CPU and GPU(s) in the loop, this may translate into improved coolant temperature.

In general, we recommend selecting a radiator in the XP series for applications where fans will run from 1200 RPM and above, and selecting among the QP series where fans will run from 1200 RPM and below. A more refined analysis including various coolant flow rate scenarios is reported in the performance section.

The XP series are available in 4 sizes: 1x120mm, 2x120mm, 3x120mm, and 4x120mm.

Weight: MCR120-XP 15oz (408g), MCR220-XP 1lb 8oz (594g), MCR320-XP 2lb (1048g), MCR420-XP 2lb 6oz (1501g)

Quality assurance: all radiators are ultrasonically cleaned to remove solder flux as well as pressure-tested for leaks.

What is Included with each radiator: M3,5 x 6mm screws (4 each per 120mm fan) – Alternatively you may use 6-32 x 1/4″ (not included) M3,5 x 30mm screws (4 each per 120mm fan) – Alternatively you may use 6-32 x 1 1/8″ (not included) Installation Warning pamphlet No fittings

In general the QP series is recommended for 1200RPM and lower where the XP is recommended for higher speeds.  The radiator is also of the slimmer 34mm thickness although it is a bit wider than some other 120mm rads measuring 128mm in width.
