Swiftech MCR420-XP eXtreme Performance Radiator

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 (from 1200 and above). When large heat loads are involved for example a CPU and GPU(s) in the loop, this may translate into several degrees improvement in coolant temperature.

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.

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

Features & Benefits:

Features	Benefits
Thermal design is optimized for maximum heat dissipation with 120mm fans featuring medium air output (1000 to 1800 rpm)	High performance cooling at moderate noise levels.
Slim form factor (34mm)	Reduces radiator intrusion on neighboring components, helps compatibility
Self-purging plenums	Help eliminate accumulation of air in the radiator, and ennoying gurgling noises
Industry standard fan spacing (15mm)	15mm fan spacing is adopted as a standard by most case manufacturers
Brass tubes	No corrosion
Copper fins	Better heat dissipation
1/4" BSPP (G1/4) threaded hubs with flat face	Compatible with industry standard G1/4 fittings with captive o-ring
Quality assurance: all our radiators are ultrasonically cleaned to remove solder flux, and individually pressure-tested for leaks!
