120mm fan modular mount for 19-inch rack

A 120mm fan mount for 19-inch rack systems with mounting space for electronics and a female USB type C plug.

This mount is part of a 19-inch modular rack mount system I designed. You can mix and match the modules with other mounts. Take a look at my models here to find out the other 19-inch mount modules.

Required Parts

• 3x M5 screws (Min size: 12mm, max size: 16mm).
• 3x M5 hex nuts.
• Female USB-C connector
• Any 120mm fan. I recommend the Noctua NF-F12 5V.
• Screws for the fan. You can use the same screws you'd use to put the fan in a computer case.
• If you get a 5V fan, you can connect it directly to USB power.

Optional

• 40mmx60mm perf board (Or similar self-designed board)
• Any step-up converter (for 5V to 12V) ex.: XL6019
• M3 screws for the electronics board. Standoffs are optional.
• Some soldering skills :)
• If you have a 12V PSU to use directly with your fan, you can use it instead of converting from USB.

Install the fan as shown in the picture below, with the airflow in the honeycomb grid direction, for better performance and less noise. If you need to change the orientation, rotate the whole mount before installing it on your rack.

Mount Assembly

OBS.: The modules used in this tutorial are only for illustration purposes, and I'm using them for the whole series. It might not reflect the models you download from this page.

• To assemble the parts, insert the 3 screws into the Right module.

• Then align it with the Left module.

• After that, insert the hex nuts in the screws, and using a screwdriver or allen key.

• Tighten the screws until you start feeling resistance and the nuts are securely into place. After that, you can install the mount in your rack.
