In the top, the maximum width of the radiator is 122 mm, and in the front, the maximum width is 151 mm.
Note that if mounting the radiator in the top of the case, you would have a maximum motherboard component height of 35 mm, so we recommend that you check your RAM height before installation.
If you plan on running a 360 mm radiator in the front along with 3.5" drives, we recommend that you move over to this article as there could be interference depending on how you mount the drives.
