I thought it was grille then radiator then fan
no, the airplex evos only have mounting points on one side
you can use a docking module (Art.-Nr.32050) to mount the fans on the other side of the rad. Actually, in this case you'll need three!
However, depending on the thickness of the case material you may need to put some spacers between the rad, and the mounting plate, as the rad has a larger footprint than three 120mm fans! That is, if you don't make the hole in the case larger to accomodate this.
