360mm PC Radiator external mount

360mm Radiator Side Mount: Glass Hook + Bottom Standoff (v1.0)

A two-piece mount that holds a 360mm AIO radiator upright beside your case, hanging from the side glass panel. I designed it for the Gigabyte AORUS RTX 4090 XTREME WATERFORCE radiator on a Lian Li O11 Dynamic, but it works with any 360mm rad that uses standard 120mm fan screw holes.

WHAT'S INCLUDED

- Top hook frame: screws into the rad's back-face fan holes, spans a 70mm gap to the glass, and hooks over the glass's top edge. The screw slots are 45mm tall so you can adjust the height, and the arm passes under any AIO tubing.

- Bottom standoff: screws into the bottom two fan holes and presses flat against the glass, so the rad stays parallel to the case.

SPECS

- Fan hole spacing: 105mm center to center (standard for 120mm fans)

- Screw slots: 3.4mm for M3 screws

- Hook slot: 6.0mm, for glass up to about 6mm thick

- Rad-to-glass gap: 70mm

HARDWARE

- 4x M3 screws, about 10mm long (check that they don't bottom out in the rad)

- 4x M3 washers (6.8mm OD or larger)

PRINT SETTINGS

- PETG

- 4 walls, 40% gyroid infill, 5 top and 5 bottom layers ( you can probably do less)

- Supports enabled

INSTALL

1. Screw the bottom standoff onto the rad's bottom two fan holes.

2. Loosely attach the top frame to the top fan holes.

3. Stand the rad next to the case and drop the hook over the glass's top edge.

4. Slide the top frame until the hook is fully seated, then tighten the screws.

NOTES

- The glass's top edge must be exposed for the hook to sit on. On my O11 the glass panel is modded to stand out 18mm from the chassis.
