This product is intended for installation by expert users only. Please
consult with a qualified technician since improper installation may
result in damage to the equipment. EK assumes no liability whatsoever,
expressed or implied, for the use of this product, nor its installation. The
following instructions are subject to change without notice. Please visit
our website at www.ekwb.com for updates. Prior to the installation of
this product, please read important notice, disclosure, and warranty
stipulation printed on the back of the box.
Before you start using this product, please follow these basic guidelines:
Carefully read the manual before beginning with the
installation process!
Remove your motherboard from the chassis for the safest
mounting process and to prevent damaging your CPU and/or
motherboard’s circuit board (PCB).
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.
Do not use pure distilled water as a cooling liquid! For best
results, EK recommends the use of EK-CryoFuel Coolants.

PREPARING YOUR MOTHERBOARD
REMOVING THE PLASTIC I/O COVER
Unscrew the four (4) screws to remove the plastic I/O cover. This
plastic cover can be reused once you’ve installed the water block.
For easier installation of the water block, we recommend you
disconnect the LED connector first.

- 7 -
REMOVING THE STOCK COOLER
Remove all encircled screws and washers. There are six (6) screws
on the back of the motherboard that need to be removed before you
can take off the factory-installed MOSFET cooling solution.
After removing the screws, carefully detach the stock cooler and pre-
applied thermal pads. EK provides replacement thermal pads with the
water block (see Chapter: Cutting and Placing Thermal Pads).

- 8 -
CUTTING AND PLACING THERMAL PADS
Your monoblock comes with thermal pads that need to be trimmed
to fit the voltage regulation area (MOSFET) on the motherboard’s
circuit board.
Thermal Pad
F 1.0mm
Place larger strips of thermal pads over the marked area and make sure
all MOSFET and inductor chips are covered, as shown in the picture.
CAUTION: Remove the protective foil from both sides of a
thermal pad before installation.

APPLYING THERMAL COMPOUND
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!

PLACING THE BLOCK ON THE MOTHERBOARD
Carefully place your EK-Quantum Momentum ROG Maximus XII
Hero water block on the motherboard or vice versa, as shown in the
picture. Make sure the mounting holes are aligned.
ATTACHING THE BLOCK TO THE MOTHERBOARD
STEP 1
Before you fasten the screws, make sure the mounting holes on the
motherboard’s circuit board are aligned with the water block. When
tightening the screws, do not use excessive force!
For the CPU:
Use four (4) M4 X 8 DIN7984 screws and M4 PVC washers. Tighten
the screws evenly using the enclosed 2.5mm Allen Key.

For the Mosfet:
Use four (4) M2.5 x 5 AX1 screws with M2.5 PVC washers and tighten
them evenly. The water block installation is now complete.
STEP 2
Attach the I/O cover back on the motherboard. Do not forget to plug
in the I/O cover LED connector before securing the screws.

STEP 3
For the EK-Quantum Momentum ROG Maximus XII Hero monoblock to
operate properly, the G1/4 port nearest to the right edge of the water
block MUST BE USED AS THE INLET PORT.
STEP 3
IMPORTANT:
Use this opening
as the Inlet Port!

CONNECTING THE DRGB LED STRIP
Plug the 3-pin connector from the monoblock’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.

To make sure the installation of EK components was successful, we
recommend you perform a 24-hour leak test.
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.
Inspect all parts of the loop, and in case the coolant leaks, fix the
issue and repeat the testing process. To prevent possible damage,
ensure that all hardware is dry before the system is powered on.
TESTING THE LOOP
