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!

REPLACING THE JET PLATE PROCEDURE

STEP 1

Please observe the table below to determine the optimal combina-

tion of insert and jet plate for your type of socket:

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.

STEP 4

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.

STEP 3

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.

LGA-115x SOCKET MOTHERBOARDS

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.
