Before you start using this product, please follow these basic guidelines:
Please carefully read the manual thoroughly before beginning
the installation process!
Please remove your motherboard from the computer to
assure the safest mounting process in order to prevent any
possible damages to your CPU and/or motherboard’s circuit
board (PCB).
The EK-Fittings require only a small amount of force to screw

rubber o-ring gaskets.
The use of quality, market-proven corrosion inhibiting
coolants is always strongly recommended for any liquid
cooling system.

Place the motherboard on the flat surface and carefully remove the stock
cooler and backplate. Do not forget to unplug all the LED connectors.
Pay attention to the following steps in order to install the EK-Quantum
Momentum² ROG Crosshair VIII Extreme D-RGB water block.
Always remove the stock cooler and backplate slowly - it might
be firmly glued to the motherboard via thermal pads.

STEP 1
EK-Quantum Momentum² ROG Crosshair VIII Extreme D-RGB water
block comes with Thermal Pads that have to be cut into smaller
pieces to cover all the regulation area (Mosfet) on the motherboard.
EK made sure to provide you with more than an adequate quantity of
Thermal Pads to complete this Step.
Please remove the protective foil from both sides of the
thermal pads prior to installation!
Replacement thermal pads:

Thermal Grease
STEP 1
Apply the enclosed EK-TIM Ectotherm thermal grease (thermal
compound) on the CPU heat spreader – IHS – as shown in the
image. The layer of the thermal compound must be thin and even
in thickness over the entire surface of the IHS.
The excessive or uneven application of thermal grease
may lead to poor performance!
STEP 1
APPLYING THERMAL COMPOUND
For this step, you will need:
PREPARING THE WATER BLOCK FOR INSTALLATION
STEP 1
Unscrew four (4) Velocity2mounting nuts (turn them in an
anticlockwise direction to unscrew). Remove the backplate and
save it for later steps. After the backplate is removed, do not
forget to peel off the protective sticker.

ATTACHING THE WATER BLOCK
STEP 1
Carefully place the water block onto the motherboard and align four
(4) mounting screws with four (4) holes on the motherboard. Hold
the water block and the motherboard and turn them upside down.
Before placing the Water Block on the motherboard, make
sure all the Thermal Pads are placed correctly! (Chapter:
Cutting and placing thermal pads).
STEP 1
For this step you will need:
Phillips Head Screwdriver
STEP 2
Secure the water block using four (4) M2.5x4 AX1 screws and M2.5
PVC washers. Do not use excessive force!
EK recommends using the EK-Loop Torque Screwdriver - 0.6Nm:

STEP 3
After securing the water block, the stored backplate must be attached to
the backside of the motherboard using Allen Key 2.5 mm (shown in the
picture) or EK-Loop Torque Screwdriver. Start fastening the backplate
screws in a cross pattern. Do not tighten fully until all of the nuts are
partially screwed in. The Allen Key 2.5mm must be used in a standing
position! Otherwise, the mounting screws may crack during tightening!
Do not remove the protective sticker from the backplate!
Make sure to orientate the backplate as illustrated. Incorrect installation
of the backplate may result in damage to the motherboard.

STEP 4
Carefully place the replacement cover onto the motherboard and
align four (4) mounting screws with four (4) holes on the motherboard.
Hold the replacement cover and the motherboard and turn them
upside down.

STEP 6
With the EK-Quantum Momentum² ROG Crosshair VIII Extreme
D-RGB, it is mandatory to use the bottom port as the INLET. Mixing
the ports may result in poor thermal performance of the water block.
Tighten the fittings in a clockwise direction until the gasket
underneath is compressed.
The installation of the water block is now complete.

CONNECTING THE D-RGB LED STRIP
STEP 1
Plug the 3-Pin connector from the water block’s D-RGB LED light
to the DRGB HEADER on the motherboard. The LED will work
if the pin layout on the header is as follows: +5V, Digital, empty,
Ground.
Please ensure that the arrow indicated on the connector is
plugged into the +5V line as indicated on your motherboard.
If you put the LED Diode to the 12V RGB HEADER you
can damage the LEDs. Failure to do so will damage your
motherboard or LED strip.

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 power to any of the 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 distribution plate. Inspect all parts of the loop, and
in the eventuality, that 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.
TESTING THE LOOP
