TESTING THE LOOP

To make sure the installation of EK components was successful, we
recommend you perform a leak test for 24 hours.
When your loop is complete and filled with coolant, connect the pump
to a PSU outside of your system. Do not connect the power to any
other components!
Turn on the PSU and let the pump run continuously. It is normal for the
coolant level to drop during this process as air collects in the reservoir.
Inspect all the parts of the loop, and in the case of coolant leaks, fix
the issue and repeat the testing process. Ensure that all hardware is
dry before the system is powered on in order to prevent any damage.
4-PIN PWM FAN
CONNECTOR
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).
