I tested all three fan outputs. Another thing is weird: pwm1_mode has
its meaning reversed (it's a 3-pin connector and the value 1 is DC
mode, in contrast to pwm2 and the documentation).

fan1 is controlled by pwm1, which is labelled as CHA_FAN (3-pin connector)
fan2 is controlled by pwm2, which is labelled as CPU_FAN (4-pin connector)
fan3 does not exist
fan4 is not yet controlled, but is labelled PWR_FAN (3-pin connector)
fan5 does not exist

Best,  CC
