Finish and Features

The PE360 has one of the densest fin counts of the test group with 18 FPI (fins per inch) measured in numerous places. This split fin combination could lead to some pretty good performance relative to the radiator thickness and the core thickness in particular.

EK have opted to include generous internal shroud depths – 9mm on the port side & 8mm on the other. This extra space between the fans gives the fans the best chance of achieving their maximum cooling potential by trying to eliminating as much of the hub’s “dead spot as possible.

I really believe this extra internal shroud would be beneficial to many of the current radiators performance so I was glad to see that EK have chosen to go down this more traditional design of function & performance. As mentioned both sides have generous depth so I assume that EK designed the radiator for optimal performance, that is using push/pull fans. The fin installation was a bit sloppy on the sample EK sent, but the spacing was quite even up and down the rows.

The EK PE360 is finished in a matte black paint which has a slightly rough feel to it.  For the modders out there, in particular the painters, the PE360 design allows for much easier custom painting by allow the core to be removed from the radiators encasing. The ports unscrew from the tank end and with the right size torx key the aluminum pieces can be taken off, allowing the core to be removed completely if the casing is to be painted.

The two long sides of the casing have a bit of flex in them, which doesn’t give the feel of being solid and sturdy. Of course once a few fans are attached everything stiffens up. Still my initial impression was that the PE felt just a bit on the flimsy side of solid.  Next to one of the ports is an EK badge and at the other end EK decided to put some lettering, reminding us of which series radiator we purchased.

Let’s see how it performs…
