EK-Quantum Momentum ROG Maximus XII Hero Monoblock
USER GUIDE
Important Information & Guidelines
This product is intended for installation by expert users only. Consult with a qualified technician, as improper installation may result in damage to the equipment. EK assumes no liability whatsoever, expressed or implied, for the use or installation of this product. Instructions are subject to change without notice. Visit www.ekwb.com for updates. Prior to installation, please read the 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 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, as the liquid seal is ensured with 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 cover can be reused after the water block is installed. For easier installation, it is recommended to disconnect the LED connector first.

Removing the Stock Cooler
Remove all six (6) encircled screws and washers on the back of the motherboard to detach the factory-installed MOSFET cooling solution. After removing the screws, carefully detach the stock cooler and its pre-applied thermal pads. EK provides replacement thermal pads with the water block.
[Diagram description: Motherboard layout showing screw locations for stock cooler removal, indicated by arrows.]
Cutting and Placing Thermal Pads
Your monoblock includes thermal pads that need to be trimmed to fit the voltage regulation area (MOSFET) on the motherboard's circuit board. The thermal pads are 1.0 mm thick, with dimensions of 120mm x 16mm.
Place the trimmed thermal pads over the marked areas on the motherboard, ensuring all MOSFET and inductor chips are covered as shown in the diagram.
CAUTION: Remove the protective foil from both sides of each thermal pad before installation.

Applying Thermal Compound
Apply the enclosed EK-TIM Ectotherm thermal grease (thermal compound) onto the CPU heat spreader IHS. The layer of thermal compound must be thin and even across the entire surface of the IHS.
Warning: Excessive or uneven application of thermal grease may lead to poor performance!
For this step, you will need: Thermal Grease (EAN: 3830046998446).

Placing and Attaching the Block on the Motherboard
Placing the Block on the Motherboard
Carefully place your EK-Quantum Momentum ROG Maximus XII Hero water block onto the motherboard, ensuring the mounting holes are aligned. The diagram shows the monoblock being positioned over the CPU socket.

Attaching the Block to the Motherboard
STEP 1 (For CPU):
Before fastening the screws, ensure the mounting holes on the motherboard's circuit board are aligned with the water block. When tightening, do not use excessive force.
Use four (4) M4 x 8 DIN7984 screws and M4 PVC washers. Tighten the screws evenly using the enclosed 2.5mm Allen Key [icon: ?].
[Diagram description: Close-up of CPU mounting area showing screws and washers being installed.]
STEP 2 (For MOSFET):
Use four (4) M2.5 x 5 AX1 screws with M2.5 PVC washers. Tighten them evenly. The water block installation is now complete.
Attach the I/O cover back onto the motherboard. Ensure the I/O cover LED connector is plugged in before securing the screws.

STEP 3: Inlet Port Designation
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.
[Diagram description: Monoblock highlighting the specific G1/4 port designated as the inlet.]
Connecting the D-RGB LED Strip
Plug the 3-pin connector from the monoblock's D-RGB LED strip into the D-RGB Header on the motherboard. The LEDs will function correctly if the header pin layout is as follows: +5V, Data, Empty, Ground.

Testing the Loop
To confirm the successful installation of EK components, a 24-hour leak test is recommended.
Once the loop is complete and filled with coolant, connect the pump to a PSU independently of other system components. Turn on the PSU and allow the pump to run continuously.
Inspect all parts of the loop for leaks. If leaks are found, fix the issue and repeat the testing process. To prevent potential damage, ensure all hardware is completely dry before powering on the system.
