This product is intended for installation only by expert users.
Please consult with a qualified technician for installation. Improper
installation may result in damage to your 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 web site at www.
ekwb.com for updates. Before 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:
Please carefully read the manual thoroughly before beginning
with the installation process!
Please remove your motherboard from the computer to assure
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
them firmly in place since the liquid seal is ensured by the
rubber o-ring gaskets.
The use of quality, market proved corrosion inhibiting coolants
is always strongly recommended for any liquid cooling system.

PREPARING YOUR MOTHERBOARD
REMOVING STOCK COOLER
Remove all encircled screws. There are 4 screws on the back of the
motherboard, that need to be removed in order to remove the factory
installed MOSFET cooling solution. Additional 4 screws need to be
removed to remove I/O cover. You can attach the I/O cover back,
after you mount the Monoblock.

APPLYING THERMAL COMPOUND
Apply thermal compound on CPU heat spreader (IHS) with enclosed
EK-TIM Ectotherm thermal grease. The quantity of about two rice
grains is just about right. There is no need to cover the whole IHS.
Applying too much thermal grease will have negative impact on the
cooling performance!
CUTTING THERMAL PADS
Your block comes with thermal pads which needs to be trimmed
in order to fit the voltage regulation area (MOSFET) on the
motherboard’s circuit board.
WARNING: Dimensions on pictures below are scaled.
PLACING THERMAL PADS ON THE
MOTHERBOARD
Place thermal pads on PCB as shown on the picture.
Please remove the protective foil from both sides of the
thermal pads prior to installation!
Place 1mm Thermal Pads in larger strips over the marked
area and make sure all mosfet and inductor chips are covered.

STEP 2
For the EK- Quantum Momentum ROG Crosshair VIII Hero
Monoblock series water block to operate properly the G1/4 port
nearest to the right edge of the water block MUST BE USED AS
THE INLET PORT.
EK recommends the use of EK- Fittings. When using fittings other
than EK series please use hose clamps or appropriate substitute
to secure the tubing to the barb. The use of biocide containing and
corrosion inhibiting coolant is always recommended for any liquid
cooling system.
CONNECTING THE D-RGB LED STRIP
Plug the 3-pin connector from Monoblock D-RGB LED strip to the
motherboard.
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 LED strip.
