Dimensions Measured on the radiator tested (retail unit):

There are some variances between my measurements and the specs listed by Alphacool. I measure the dimensions of the housing, then add extra in brackets which would be required if stop plugs are installed in unused ports.

I double checked my measurements and they were correct. Then I checked against the Tech Drawing dimension, and they are different again, so I really don’t know what Alphacool are measuring against (or with).

Radiator Core Dimensions:

The core is four layers deep x 10 tubes wide of 15mm x 1.5mm copper tubes run parallel in a standard U-Pattern flow path. The single louvered fins were laid out quite evenly between the rows of tubes and have an averaged count of 10 FPI (Fins Per Inch). The following pic however shows about 11 FPI on the fins each side of the ruler.

Finish and Features

The Monsta has a satin black finish, which is in between a full gloss and matte black. The finish is nice and smooth and I found that my sample to be blemish free, as good as one could hope for.

A White Special Edition Monsta 360 is also currently available.

The Monsta 360 comes equipped with 7 ports in total.

3 inlet and 3 outlet, offering every possible combination available (on a U-Flow Rad) for placement of fittings, a fill port, and a drain port. This is as good as it gets!!

In addition, another port is fitted on the return end tank, offering further options for filling, draining or air bleeding when mounted in a vertical installation.

Note: The bleeder port is not intended to be used as a fitting port.

There are screw protector plates fitted under the M3 threads for case installation and fan attachment. As the mounting holes are located directly over the top of the outside tubes, theses plates would save the rad from almost certain irreparable damage if the wrong length screws were used.

So we have a massively thick radiator that has a low density fin structure on it’s thick core. I can’t help but think that the Monsta should have some amazing heat dissipation in the low fan speed Push/Pull tests, but I’ve been wrong before so…..let’s see how it performs.
