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

STEP 2: 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 heat pipe cooling solution. Additional 4 screws need to be removed
to remove the plastic I/O. Please store the removed material away for later use. You
can attach the I/O cover back, after you mount the Monoblock.

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.

Do not remove

the PCH (SB)

STEP 3: PLACING THE BLOCK ON TO MOTHERBOARD STEP 4: CONNECTING THE D-RGB LED STRIP

PLACING THE BLOCK ON THE MOTHERBOARD. Place the EK-FB Maximus XI HERO
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 use for M2.5
adhesive PVC washer on Maximus XI HERO motherboard (as the motherboard has
its own washers already glued by manufacturer)

Plug the 4-pin connector from Water block’s D-RGB LED light to the DRGB_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 5: 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 PVC washers. Tighten the
screws evenly. Do not use excessive force when tightening the screws!
B) CPU part: Use four (4) M4x8 DIN7984 with screws and washers.
Tighten the screws using enclosed 2.5mm Allen key.

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

For the EK-FB Maximus XI 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-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.
