BD9 Cooling Fan Mount for 30mm Fans - B9-CFMA by Yokomo  [B9-CFMA]

BD9 aluminum fan bracket overview

This aluminum cooling fan mount is made for the BD9 touring chassis family and provides a compact, purpose-built bracket to secure a small cooling fan (fan sold separately). It is offered as an aftermarket accessory to help manage electronics and motor temperatures during track sessions and bench setup.

Installation on BD9-series chassis is simple: the mount locates on the BD9 fan/mounting area and fastens to the chassis using the existing screw points, so small machine screws are required but not included. The bracket accepts widely available 30mm square fans and places airflow where electronics or the motor benefit from direct cooling.

When carrying out setup or short test runs, this mount can reduce temperature variance and help produce more consistent motor and electronics behavior without changing the main chassis geometry.
