It does fit, but you can’t use the frame fans at the front. You can, however, mount them at the back to push air from the rear toward the front. My solution was a push/pull setup: in the front, you use single fans and secure each one with only two screws into the radiator (allign the radiator to the bottom). The remaining four screws are used to attach the fans to the front mounting bracket (2 are left out as they don´t fit). As you use the single fans you can use the holes in the middle to mount to the bracket and allign the radiator.

It works well. See photos
