Swiftech MCR320-QPK 360mm Radiator Review

Welcome to another Extreme Rigs 360mm radiator review. Today we have another Slim 360mm radiator under scrutiny, this time it’s the Swiftech MCR320-QPK. Our review sample is the “standard” radiator only version, however Swiftech also offer the same radiator with a built in reservoir (MCR320-QP-RES-R2).  In addition the MCR320-DRIVE-R3 variant sports both a reservoir and pump fitted directly to the radiator. The QP series (Quiet Performance) is designed for maximum efficiency with low to medium speed fans while the XP Series (eXtreme Performance) is targeted for medium to high speed fans.

In this MCR320-QPK review we’ll be taking a close look at it’s construction, analyzing the performance data and comparing it’s results against the other 360mm radiators we have tested.

Firstly a big thanks to Performance PCs for providing the review sample of the MCR320-QPK. PPCs has often stepped up to the plate to fill in gaps in our roundups.  The support offered by PPCs is greatly appreciated by Extreme Rigs and ultimately means you the reader can make more informed purchase decisions.



What’s in the Box?

The MCR320-QPK sample arrived in full retail packaging which is about as simple as it gets. A plain white box and a part number sticker.
Flipping open the carton we are pleased to see the radiator is packaged with a bubble wrap protection bag.
A screw length warning sheet is also included.

Make sure the screws you are using do not hit the water channels!

Depending on your configuration you might want to use your own screws either to attach the fan to the radiator, radiator to the chassis, or using a Radbox.  You can use either 6-32 US thread or M3.5 metric thread. But always double-check the screw length before installation or you might poke a hole in the radiator water channels!
Swiftech Screws Warning


The included accessories are placed at the end of the carton in a zip-lock bag.  There is no cardboard divider to stop the screws moving.


Extent of delivery as listed by Swiftech:

  • 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)
  • Fill-cap (MCRx20-QP-RES series)
  • Installation Warning pamphlet
  • No fittings

12 screws of each length are provided with the MCR320-QPK, so there are enough to install the radiator with either Push OR Pull fans mounted to a case panel, BUT NOT Push/Pull.

Both sets of screws are listed as having M3.5 threads which we do not recall seeing from any other manufacturer. Swiftech advise that a 6/32 thread could also be used and we did in fact use UNC 6/32 screws without any issue when mounting the MCR320-QPK into the thermal test rig.

The thread length of the longer set is ~30mm and the shorter screws measure in at 6mm.


Onwards to technical specifications!
