Installation manual for EK-FB GA X399 GAMING RGB Monoblock water block

x399 GAMING RGB Monoblock

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 website at www.ekwb.com for updates.
Before installation of this product please read the 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 the safest mounting process in order to prevent any possible damage to your CPU and/or motherboard’s circuit board (PCB).
3. The EK-HFB and EK-ACF type 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, the market proved corrosion inhibiting coolants is always strongly recommended for any liquid cooling system

STEP 1: GENERAL INFORMATION

Sample photo of GA X399 AORUS Gaming 7 motherboard

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

REQUIRED TOOLS AND MOUNTING SCREWS:

STEP 2: PREPARING YOUR MOTHERBOARD

REMOVING STOCK COOLER AND I/O COVER. Remove all encircled screws. There are 4 (four) screws on the back of the motherboard that need to be removed in order to remove the factory-installed MOSFET cooling solutions and 3 (three) screws that need to be removed in order to remove the I/O cover for easier Heatsink installation. You may have to disconnect the RGB connector!

STEP 3: PREPARING YOUR MOTHERBOARD

APPLYING THERMAL COMPOUND. Apply thermal compound on the CPU heat spreader (IHS) – see the sample photo below with the enclosed thermal grease.
The quantity of about two stripes is just about right. There is no need to cover the whole IHS. Applying too much thermal grease will have a negative impact on the cooling
performance!

STEP 4: CUTTING THERMAL PADS

Your block comes with thermal pads which need to be trimmed in order to fit the voltage regulation area (MOSFET) on the motherboard’s circuit board.
WARNING: DIMENSIONS ON THE PICTURES BELOW ARE SCALED.

1. Thermal pad G– 1.0mm (for MOSFET and CHOKES)
2. Thermal pad F– 2.0mm (for Heatsink)
   Replacement thermal pads @ EKWB webshop:
   Thermal PAD G 1mm – (120x24mm) [EAN: 3830046996770] Thermal PAD F 2mm – (120x16mm) [EAN: 3830046996756]

**STEP 5: PREPARING THE MONOBLOCK AND HEATSINK

**

Place the M2,5 self-adhesive PVC washers under marked standoffs!

STEP 7: PLACING THERMAL PADS

Place thermal pads on PCB as shown on the picture below.
PLEASE REMOVE THE PROTECTIVE FOIL FROM BOTH SIDES OF THE THERMAL PADS PRIOR TO INSTALLATION!

STEP 8: PLACING A HEATSINK ON THE MOTHERBOARD

Place the Heatsink gently to the motherboard as shown on the picture below; make sure that mounting holes are aligned.

STEP 8.1: ATTACHING THE HEATSINK TO THE MOTHERBOARD
Before you fasten the screws please make sure that the mounting holes on the motherboard’s circuit board are aligned with the heatsink.

STEP 9: PLACING A BLOCK ONTO THE MOTHERBOARD

Place the EK-FB GA X399 GAMING RGB Monoblock gently to the motherboard or vice versa (as shown on picture below). Make sure that mounting holes are aligned.

• STEP 9.1: ATTACHING A 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. Secure top 4 (four) nickel screws with an enclosed 2,5mm Allen key. Tighten screws diagonally and evenly till the end of the thread. Do not use excessive force when tightening the screws!

STEP 9.2: ATTACHING A 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. Use 2 (two) M2,5×5 AX1 screws with M2.5 PVC washers. Tighten the screws evenly. Do not use excessive force when tightening the screws!

STEP 10: CONNECTING THE RGB LED STRIP (optional)

CONNECT THE RGB LED (RGB LED with 4 wires): Plug the 4-pin connector from the Monoblock RGB LED strip to the LED_C1 on the motherboard. Please ensure that the arrow indicated on the connector is plugged into the +12V line as indicated on your motherboard. Failure to do so will damage your motherboard or LED strip. You should leave the final pin, marked as “W”, empty.

CONNECT THE D-RGB LED (LED with 3 wires):
5V D-RGB LED is enclosed with your monoblock. If you swap the LED strip, plug the 3-pin connector from the Monoblock D-RGB LED strip to the D_LED header on the motherboard. Please ensure that the arrow indicated on the connector is plugged into the V line as indicated on your motherboard. Failure to do so will damage your motherboard or LED strip.

For the EK-FB GA X399 GAMING Monoblock series water block to operate properly the lower G1/4 port of the water block MUST BE USED AS THE INLET PORT. EK
recommends the use of EK-ACF fittings. When using fittings other than the EK- ACF series please use hose clamps or appropriate substitutes to secure the tubing to the barb. The use of biocide-containing and corrosion-inhibiting coolant is always recommended for any liquid cooling system.

All disclosures, notices, and warranty conditions are being written on the EKWB web page.
Please check the terms of use.
