Selecting a Heatsink Fan for Apalis SoMs
Fans intended to mount on the Apalis heatsinks need a screw hole pattern of 32x32mm. This is the case with the standard 40x40mm fan.
The fan has to run on 12V which gets supplied by the 3 pin connector X35 on the Apalis Evaluation Board or on X6 on the Ixora Carrier Board. Both carrier boards have the option to control the fan with Apalis GPIO8. The 3rd pin which is speed feedback is not connected on any of our carrier boards.
Too long screws which go through the heatsink and are sticking out on the bottom of the heatsk can damage the module! Make sure the screws aren't too long.
In addition to the Apalis Heatsink Fan, the fans listed below are compatible with M2.5x14mm screws. The screw heads should be between 4.5 and 5mm wide.
