the alarm is "overcurrent,fan output deactivated",whats happend?

i don't know how to solve the problem.

It looks like the current draw on your Fan Port 3 exceeded the working limit.
From the Aquaero Manual:

aquaero 6:
Maximum current is 2.5 A per output independent of output voltage, resulting
in a maximum power of 30 W at 12 V. Outputs will be switched of if
amplifier temperatures reach a critical level and will automatically be reactivated
when cooled down. If an output current of 3 A is exceeded, the output
will be permanently disabled. To reactivate the output, the aquaero (or
the complete PC) has to be disconnected from power for a short period of
time. The fan outputs are short-circuit proof.
All fan connectors can be used for conventional fans or PWM controlled
fans. For PWM fans, select “Outputs” → “Fans” → “Fan 1-4” from the menu
and set “Control mode” to “PWM controlled”.

For PWM fans, select “Outputs” → “Fans” → “Fan 1-4” from the menu
and set “Control mode” to “PWM controlled”.《《《I tried all the mode .but Cannot start again。
