Connector
The EK-D5 PWM pump has two following connectors:
1. 4-Pin Molex - Must be connected directly to your
PSU at all times as it’s used to power the pump.
2. 4-Pin PWM Fan Connector – Can be connected to
your motherboard’s CPU, fan, or designated water
pump header, as well as a controller. This cable is
used to control and report the rotational speed of
the pump. If it’s not connected, the pump will run at
its maximum speed (100% PWM).
