CONNECTING THE PUMP
The EK-VTX Pump has two connectors:
1. 4-Pin Molex
– must be connected directly to your
PSU at all times as it is used to power the pump;
2. 4-Pin PWM
Fan – can be connected to your
motherboard CPU Fan or designated water pump
header. It can also be connected to 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 maximum speed (100% PWM).
