Low-Profile 120 mm Fan Desk Stand – Under-Monitor Personal Cooling Bracket

Turn a spare 120 mm PC fan into an unobtrusive desktop breeze. This low profile stand slides beneath most monitors, aiming cool air straight at you.

Id recommend to pair with Noctuas NV-AA1-12 Airflow Amplifier that you can print yourself, then power the fan from a motherboard PWM header or an Arduino + 12 V power supply (let me know if you want the Arduino guide).

Key Features

Low profile – fits under nearly any monitor without blocking the view

Universal 120 mm mount – 105 mm hole spacing, works with all PC fans

Tilt adjustment – pivot hinge sets the perfect face-cooling angle

Hardware & Assembly Notes

Uses M5 × 15 mm screws with round head.

The holes in the “Screw Objects" are intentionally undersized so the screws can be warmed slightly and melted in for a press-fit thread. If heat-setting isn’t possible, a small drop of super-glue works too.

Matching M5 heat-inserts are pressed into the side pieces; the thumbscrews thread into these inserts for a solid, repeatable tilt adjustment.
