Taking a closer look at the fan that is included and we can see it has 11 fins to help push air through the radiator and as mentioned it is 20mm thick and has a 4-pin PWM connector.
Taking a look at the AIO unit and it features a 120mm radiator, ribbed tubing and the pump/block features the Gamer Storm logo which also has a nice breathing glow to it once installed.
A closer look at the fins on the radiator reveals they have a nice bit of space in between them.
The Maelstrom 120K comes with Thermal Paste pre-applied so it is ready for installation straight out of the box.
Once the fan is installed the whole unit should fit in well with most builds as it is literally all black. While I am all for a bit of colour accenting on products this is a nice touch, as mentioned it is all black so will fit in nicely.
One thing that I noticed when I cleaned the thermal pastse off was that there are quite a few nicks and dents in the copper baseplate. While this is really no big deal it is an issue that needs to be addressed and corrected in my opinion.
