Every GPU anti-sag support I found needed an empty case floor. Mine has fans there, so I designed one that mounts on the fans.

New PC, heavy GPU (RTX 5080), and bottom intake fans, so there’s no floor to rest a support on. I couldn’t find a single model that handled this, so I made one.

It bridges two 140 mm fans using their existing screw holes and covers only ~3 % of the fan area, so airflow isn’t affected. The tower slides onto a hex rail, and a printed Tr12×3 threaded rod with a lock nut does the fine adjustment. After a few overengineered iterations (pics included 😅), I went back to a simple, industrial design.

It comes in 2 height ranges from ~80 to ~154 mm, measured from the top of the fan frame to the underside of the GPU. The minimum safety factor is ~7, including PETG creep at 50 °C. It has swappable nameplates (RTX, NVIDIA, RADEON, or blank), prints without supports, and the profiles are ready for Bambu printers. Hardware: just 4 standard fan screws.

White base, black hex part: on a white build it looks like it’s floating. Print it in PETG, not PLA.

Currently for 140 mm fans. If enough people want a 120 mm version, let me know and I’ll make one.
