Thanks to the perfect circular cutouts the fans will work at their maximum efficiency. The distance between the two fans is variable to work with most radiators. Please take a look at the technical drawing to see if the mountplate fits with your build before you buy.
Only while stocks last, I now also offer a couple of aluminum Mountplates for free to add to your order. These are leftovers from early development but will fit and function as the real mountplates but are not so stable. They are not coated, so have a silver finish.
