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:

1. Please carefully read the manual thoroughly before beginning with the installation process!

2. 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).

3. 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.

4. The use of quality, market proved corrosion inhibiting coolants is always strongly recommended for any liquid cooling system.

STEP 1: GENERAL INFORMATION Sample photo of motherboard:

BAG CONTENT: Bag content is universal for all water blocks, you may not need all screws.

STEP 1: PREPARING YOUR MOTHERBOARD

STEP 2: PREPARING YOUR MOTHERBOARD

REMOVING STOCK COOLER. Remove all (7) encircled screws. There are screws

on the back of the motherboard that need to be removed in order to remove the
factory installed MOSFET heat pipe cooling solution.

1. APPLYING THERMAL COMPOUND. Apply thermal compound on CPU heat
spreader (IHS) - see sample photo on right 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!

2.. 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.

3. PLACING THERMAL PADS ON MOTHERBOARD. Place thermal pads on PCB as shown on the picture below.

STEP 3: PLACING THE BLOCK ON TO MOTHERBOARD

Place the EK-Momentum Z390 MEG Godlike Monoblock series water block gently
to the motherboard or vice versa (as shown on photo below). Make sure that
mounting holes are aligned. There is no need for M2.5 adhesive PVC washer on

MSI Z390 MEG GODLIKE motherboard.

Plug the 3-pin connector from Water block’s D-RGB LED light to the D-RGB 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.

STEP 4: ATTACHING BLOCK ON TO THE MOTHERBOARD

Prior to fastening the screws please make sure the mounting holes on the
motherboard’s circuit board are aligned with the water block.
A) Mosfet part: Use four (4) M2,5x5 AX1 screws with M2.5(0.5mm) PVC
washers. Tighten the screws evenly. Do not use excessive force when tightening
the screws!
B) CPU part: Use four (4) M4x8 DIN7984 screws and M4(0.8mm) washers.
Tighten the screws using enclosed 2.5mm Allen key.

Use the enclosed screws and washers as shown in picture below:

For the EK-Momentum MSI Z390 MEG Godlike 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.
