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-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, market proved corrosion inhibiting coolants is always strongly recommended for any liquid cooling system.

BAG CONTENT: Bag content is universal for all water blocks, you may not need all screws.
STEP 1: 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 3 screws need to be removed to remove
the plastic I/O cover. Please store the removed material away for later use. You can
attach the I/O cover back, after you mount the Monoblock.
Removing of the original plastic hold-down clamps and the factory backplate:
Using Philips-head screwdriver remove the four UNC 6-32 screws securing the original
plastic hold-down clamps around the socket as shown on the sketch. Remove the
original AMD® backplate and the hold-down clamps and store them away.
CUTTING THERMAL PADS. Your block comes with thermal pads which needs to be
trimmed in order to fit the voltage regulation area (MOSFETs and coils) on the
motherboard’s circuit board. WARNING: DIMENSIONS ON PICTURES BELOW ARE
SCALED.
Replacement thermal pads @ EKWB web shop:

STEP 2: PREPARING YOUR MOTHERBOARD
STEP 3: PLACING THE BLOCK ON TO THE MOTHERBOARD
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!
Install four (4) M2.5 self adhesive PVC washers under marked standoffs as shown on
the picture below.
STEP 4: ATTACHING BLOCK ON TO THE MOTHERBOARD
PLACING THE BLOCK ON THE MOTHERBOARD. Place the EK-FB ASRock X470 Gaming
K4 RGB Monoblock series water block gently to the motherboard or vice versa (as
shown on picture below). Make sure that mounting holes are aligned.
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 M2,5x5 AX1 screws. Tighten the screws evenly. Do not
use excessive force when tightening the screws!
B) CPU part: Use four M3x10 DIN7984 screws with backplate and protective pad.
Tighten the screws using enclosed 2mm allen key.
Use the enclosed screws and backplate as shown on picture below:
STEP 5: CONNECTING THE RGB LED STRIP (optional)
CONNECTING THE RGB LED (LED with 4
wires)
Plug the 4-pin connector from Monoblock
RGB LED strip to 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
have the final pin, marked as “W”, left
empty.
CONNECTING THE D-RGB LED (LED
with 3 wires)
Plug the 4-pin connector from
Monoblock RGB LED strip to 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 ASRock X470 Gaming K4 RGB 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-ACF fittings. When using fittings
other than EK-ACF 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.
