EK-Quantum Inertia D5 PWM Installation Manual
This product is intended for installation by expert users only. Please consult with a qualified technician for installation. Improper installation may result in damage to the equipment. EK Water Blocks assumes no liability whatsoever, expressed or implied, for the use of these products, nor their installation. The following instructions are subject to change without notice. Please visit our website at www.ekwb.com for updates.
Before you start using this product, please follow the basic guidelines:
Carefully read the manual before beginning with the installation process!
EK Fittings require only a small amount of force to screw them firmly in place since the liquid seal is ensured with the rubber o-ring gaskets.
The use of quality market-proven corrosion-inhibiting coolants is always strongly recommended for any liquid cooling system.

Installing the Pump
(Assembly already done by EK)
The pump assembly consists of the EK-Quantum Inertia, a 60x3 O-ring Gasket, the EK-D5 PWM G2 Motor, a Locking Ring, a Rubber Damper, a Pump Holder, and M3 x 12 DIN7984 screws.
Steps:
- Install the provided 60x3 O-ring gasket to the EK-D5 PWM G2 Motor.
- Once the O-ring gasket is in place, take the pump and place it into the EK-Quantum Inertia. You can rotate the EK-D5 PWM G2 Motor if required.
- Fix the pump onto the EK-Quantum Inertia using the locking ring.
- Take the rubber damper and place it into the pump holder.
- Once the rubber damper is installed into the pump holder, push the assembled part onto the EK-D5 PWM G2 Motor.
- Take the M3x12 DIN7984 screws and secure the EK-D5 PWM G2 Motor to the pump holder. Use the 2mm Allen Key. The plate with two M3 thread holes is preinstalled by EK.
Installing EK-Quantum Inertia D5 PWM D-RGB
The EK-Quantum Inertia D5 PWM D-RGB ships with a pump holder that can be installed directly to the computer chassis. If there are no appropriate mounting holes available, the user may need to drill four (4) 5 mm holes through the metal chassis with an electric power drill. A sticker is included to mark the hole centers accurately.
Mounting Configurations
The EK-Quantum Inertia D5 PWM D-RGB can be used in any mounting configuration (position) except upside down. Mounting the pump upside down will result in the pump running dry and potentially lead to premature failure.
Correct mounting positions are indicated with a checkmark (✔️).
Incorrect mounting positions (upside down) are indicated with a cross (❌).
Installing the Assembly Using a Pump Bracket
*An optional step; the pump bracket is sold separately.
The EK-Loop UNI Pump Reservoir Bracket is used for mounting the assembly onto 120/140mm fan mounting holes. Secure the EK-Quantum Inertia D5 PWM D-RGB onto the bracket using the enclosed M4 x 10 DIN7984 screws and M4 PVC washers.
Attaching the Fittings
EK recommends using EK-Quantum Torque Fittings with the EK-Quantum Inertia D5 PWM D-RGB series pump tops. To ensure tubes are securely attached, use hose clamps or an appropriate substitute.
- It is mandatory to use the correct INLET and OUTLET ports.
- The OUTLET is the G1/4 threaded opening on the side of the pump-top housing.
- The INLET (suction) port is the central G1/4 threaded opening on the EK-Quantum Inertia D5 PWM D-RGB front face plane.
- Ensure not to use fittings or barbs with a G1/4 thread longer than 5mm. All EK fittings are compatible.
Connecting the Pump
The EK-D5 PWM pump has two connectors:
Connectors:
- 4-Pin Molex: Must be connected directly to your PSU at all times to power the pump.
- 4-Pin PWM Fan Connector: Can be connected to your motherboard's CPU, fan, or designated water pump header, or a controller. This cable controls and reports the pump's rotational speed. If not connected, the pump runs at maximum speed (100% PWM).
Connecting the D-RGB Lights
Plug the 3-pin connector from the water block's D-RGB LED light to the D-RGB HEADER on the motherboard. The LEDs will work if the pin layout on the header is as follows: +5V, Data, Empty, Ground.
⚠️ Please, ensure that the arrow indicated on the connector is plugged into the +5V line, as indicated on your motherboard.
Failure to do so will damage your motherboard or the LED strip.
Testing the Loop
To ensure successful installation of EK components, 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 power to any other components. Turn on the PSU and let the pump run continuously. It is usual for the coolant level to drop as air collects in the distribution plate.
Inspect all parts of the loop. If coolant leaks, fix the issue and repeat the testing process. Ensure all hardware is dry before powering on the system to prevent any damage.
