the Firmware checks on power-on If a fan is connected - it enables PWM and checks If the tach-input is there. If yes it enables the kernel driver which runs the PWM under temp control (with a default fan curve it should start Spinning at 55°C).

is that a wireless Keyboard/Mouse with a USB receiver by chance?
