Water cooling is The Define S2’s forte as it has numerous locations for different sized radiators. Being modular, various panels can be detached – more notably the panel which the HDD brackets attach to can be completely removed along with the end part of the PSU shroud. This allows us better access to the front section for installing radiators.

RADIATOR – FRONT

At the front we can install360, 280, 240, 140 and 120mm radiators. We’ve attached a 280mm radiator to demonstrate the space and clearance. Since there is plenty of space at the front, it’s also possible to install fans on both sides of the radiator too.

RADIATOR – TOP

At the top, there is approximately 28mm of space between the top of the chassis and the top of the motherboard. This should be taken into account when installing any water cooling configurations.

At the top we can install 120mm all the way to 420mm radiators. Again, pictured we have a 280mm solution which comfortably sits in position, away from the motherboard due to the mounting holes being placed closer to the side panel.

All-in-all, Define S2 is a flexible chassis for those wanting to kit this case out with closed loop solutions or custom water cooling.
