CPU WATER BLOCK
1st Revision, May 17th 2019

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:
Please carefully read the manual before beginning with the
installation process!
The product must be in a non moist and temperature-stable
environment
Please remove your graphics card from the computer to assure
safest mounting process in order to prevent any possible damages
to your GPU and/or graphics card circuit board (PCB).
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.
The use of corrosion inhibiting coolants is always recommended for
any liquid cooling system.
Do not use pure distilled water! For best results EK recommends the
use of EK-CryoFuel coolants!
Make sure to thoroughly bleed air out of your water block, or you will
not reach optimal performance!

STEP 2
Unscrew the four M4 screws in counter-clock-wise direction from the
bottom of the water block using enclosed 2,5mm Allen key to release the
assembly, consisting of water block top and jet plate. Upon replacing the
jet plate please reassemble the water block as shown on the in STEP 1 and
STEP 2 pictures. Pay special attention to the insert orientation relative to
the copper base and water block top!
Before reassembly of the water block it is crucial that the
preformed gasket (o-ring) is placed into the gap between
the mounting plate and the water block top.
Screw the four screws back in but don’t exaggerate with the force applied.

STEP 1
Prepare the foil bag with mounting mechanism, which is enclosed
with the CPU water block delivery.
Install four (4) specific LGA-2011 M4 thumb screws into four M4
threaded stubs on the LGA-2011 socket integrated latch mecha-
nism (ILM). The screws are to be installed using no tools (i.e. pliers).
It is recommended to remove the motherboard form the
PC chassis before proceeding with installation of the CPU
water block because of the space constraint limitations of
various computer cases.

STEP 2
Cleaning the CPU: Wipe the CPU’s contact surface (by using non–
abrasive cloth or Q-tip, as shown on sample photo).
Applying thermal compound: On a clean IHS, apply a line of
thermal compound and spread it over the whole CPU heat spreader
(IHS) with a credit card or equivalent - see sample photo on left.
The layer of thermal compound must be thin and even in
thickness through the whole surface of the IHS. Too thick
application could lead to poor performance. This method
applies for Thermal Grizzly Hydronaut thermal compound
(3830046998477).

STEP 3
Align the water block over the mounting screws on the LGA-2011(-3)
motherboard with pre-installed CPU.
Before proceeding with the installation, It is mandatory
to remove the protective foil from the backside of the
water block.
Place an enclosed compression spring and thumb nut over each M4
thumb screw. Start fastening two thumb nuts at a time, preferably in cross
pattern and do not tighten them fully until all of them are partially screwed
in. Then - using your fingers only - screw in all four thumb nuts until you
reach the end of the thread.

STEP 5
Tighten the fitting barbs in clockwise direction until the gasket underneath
is compressed.
The installation of the CPU water block is now complete.
Before proceeding with the installation It is mandatory
to remove the protective foil from the backside of the
water block.
With EK-Lignum series water blocks it is mandatory to use the port that
is nearest to the center of the water block as INLET port. Mixing the ports
may result in less than ideal thermal performance of the water block.

Placing Wood cover:
Before proceeding with the installation It is mandatory
to remove the protective foil from the backside of the
water block.
Place Wood cover over the water block. Then - using your fingers only,
press Wood cover on water block. Don’t exaggerate with the force applied.

Install backplate rubber gasket and place metal backplate for Intel®
LGA-115x socket to the back of your motherboard RIBBED SIDE
UP! (facing away from the motherboard) Align the holes on the
motherboard with holes on rubber gasket and backplate.
Carefully rotate motherboard assembly with front side facing up
with one hand while holding the backplate and rubber in place with
the other hand.
Make sure to orientate the rubber gasket to fit past the
CPU socket ILM backplate. On certain ITX form factor
motherboards the rubber gasket may need to be trimmed
using household scissors.

STEP 1
If already installed, please remove the motherboard from your
computer and place it on an even surface with front facing down.
STEP 2
Preparing backplate rubber gasket
The enclosed rubber gasket is essential part of the backplate and
mounting system and must be used every time you install this water
block on your motherboard.
The rubber gasket has a partially cut inner part which
needs to be removed when installed on Intel® LGA-115x
motherboard. The rubber is held on four places and can
be peeled away with hand.

STEP 1
Replacing the mounting plate:
Place the water block on a neven surface and remove the four M4x14
DIN 7991 screws attaching the copper base to the top using 2,5 mm
Allen key in counter-clockwise direction.
STEP 2
Replace the Intel® factory installed mounting plate with AMD® one.
You will feel the mounting plate locking into the position when
placed correctly on to the top.
Reseat the O-ring gasket (57x2,2 mm) into the gap between the
mounting plate and water block top.
Be careful that the orientation of the copper base is as
shown on the picture
Reinstall the M4x14 screws and tighten them using 2,5 mm Allen key
to screw them in clockwise direction.

STEP 4
Install four (4) M4 thumb screws onto your motherboard. It is mandatory
to put 0.7 mm plastic washer underneath each of the M4 thumb screws.
Tighten the screws to the metal backplate until you reach the end of the
thread. Using tools (such as pliers) is not recommended.
