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.
Also note that any radiator installed in the front will lower the maximum GPU length with the thickness of the radiator. The standard maximum GPU length is 372 mm. With a radiator installed, the maximum is 372 - Radiator thickness, meaning that with a 30 mm thick radiator, the maximum GPU length is (372 - 30) 342 mm.
