The fan can also be used as a regular 2-wire 12V fan. Connect only:
Yellow Wire = +12V
Black Wire = Ground (-)
When supplied with sufficient 12VDC current, the fan will operate at full speed.
IMPORTANT: Each fan requires up to 2.5A at 12V to reach maximum speed and airflow.
For example, if you connect 4 fans, use a properly rated 12V 10A or higher power supply to provide sufficient power.
