Radxa X4 fan header not matching the schematic

#1

Hi, The Rada X4 Schematic shows a 4 pin fan header whereas on the board its a 2 pin… ?
I’m trying to get the fan working and it will not start up. Do I need some separate softaware to get the cpu fan to start on bootup?
Ubuntu.

Thanks!

The schematic is correctly showing the anchor pads that are just connected to ground.

The fan is a 2-wire fan and the connector is a 2P connector

Understand ty!
Does the fan need to be setup to work at all?

There’s no setup needed. The fan turns on as soon as the board is powered on.
