Momentum Aorus Z490 Master D-RGB

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 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.
Prior to the installation of this product, please read important notice,
disclosure, and warranty conditions 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 THE MOTHERBOARD
REMOVING THE BACKPLATE
STEP 1
Remove the two (2) encircled screws.
STEP 1
Backplate Screws
STEP 2
STEP 2
On the backside of the motherboard, six (6) additional screws
need to be removed, as marked in the picture. Once these screws
are removed, you can carefully detach the backplate from the
motherboard. The backplate can be reused after mounting the
water block.

- 7 -
REMOVING THE PLASTIC I/O COVER
STEP 1
Unscrew one (1) standoff and two (2) 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.

REMOVING THE STOCK COOLER
STEP 1
Remove all encircled screws. There are three (3) screws and
one (1) standoff on the back of the motherboard that need to be
removed before you can take off the factory-installed MOSFET
cooling solution.

STEP 2
After removing the standoff and 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).

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.

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 Aorus Z490 Master
D-RGB water block on the motherboard or vice versa, as shown in
the picture. Make sure the mounting holes are aligned.
CAUTION: The protective sticker must be removed from the
coldplate.
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 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 and backplate back on the motherboard.
Do not forget to plug in the I/O cover LED connector before securing
the screws.
M2.5 x 5 AX1
STEP 1
STEP 3
For the EK-Quantum Momentum Aorus Z490 Master D-RGB
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. Ensure that all hardware is dry
before the system is powered on, to prevent any damage.
TESTING THE LOOP
