Maximum simultaneous radiator combination is a 240 mm in the top, a 360 mm in the front, and a 120 mm in the rear.. Without rear radiator installed, the maximum is a 280 mm in the top, and a 360 mm in the front.
See below for maximum measurements of each radiator:
These are our recommended max length and thicknesses. It is possible to have slightly thicker front and top radiators at the same time, but tubing can be extremely difficult going past these measurements.
