4.1.2 Connector J1 – Fan
J1 is a connector for 3- or 4-wire fan control. By default, it is set for 4-
wire fan control. The 9W APU COMe-cOH# SKUs do not require a fan to function
fully in the 0°C to 60° temperature range. When active cooling is required,
the default population is the 4-wire fan option. See Section 6.3, “Onboard
Fan Connector” for more detailed information.
