Swiftech MCR120-XP eXtreme Performance Radiator Series

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.

 

We conducted comparative testing between the QP and XP lines, and the data is reported below :

Analysis:

 

RPM Range	Model	șC/W at 2 lpm (Low flow)	șC/W at 4 lpm (Medium Flow)	șC/W at 6 lpm (High flow)
900	QP	.057	.055	.0545
900	XP	.0595	.0585	.058
1200	QP	.043	.0405	.0395
1200	XP	.0425	.0417	.0401
1500	QP	.036	.0337	.0325
1500	XP	.0355	.0336	.033
2000	QP	.0305	.0285	.0278
2000	XP	.029	.0268	.0258

We can see above that in the 900 rpm range, the QP is better at any flow rate. Conversely, in the 2000 rpm range, the XP is better at any flow rate.

 

In between these two extremes, the results are flow rate dependant.

 

In low flow rate systems the XP is superior at any rpm range starting at 1200 rpm.

In medium flow rate systems,  the QP is better at 1200 rpm, and the XP is better at 1500 and 2000 rpm.

In high flow rate systems, the QP is better at 1200 and and 1500 rpm,s and the XP is better at 2000 rpm.
