INSTALLATION TIPS FOR NOVICES
1. To lower the shipping cost, we have decided to enclose the
coolant concentrate only. Therefore, you need to provide 1
liter (1L) of distilled water. You can find it at every gas station or
supermarket.
2. Never run this system on tap water and always use the
enclosed cooling concentrate in the right ratio.
3. Never use alcohol, alcohol derivatives, or alcohol-based
solvents in the system. Using alcohol might result in permanent
damage to water cooling KIT components, especially acrylic
parts of the system.
4. It is best practice to do a proper 24-hour leak test before using
your computer.
5. If you spot any leaks, turn the power off immediately.
6. Optimize tube length to prevent excessive bending and kinking
of the tubing.
7. Never let your pump run dry. If this is happening for a
prolonged period, you risk destroying the water pump’s bearing,
ultimately rendering the pump useless.
8. You are encouraged to periodically clean the radiator assembly
as it will collect dust over time. It’s best to be done with a soft
wide-tip brush and a vacuum cleaner. See chapter Universal
Cleaning Guide.

GENERAL INFORMATION ON WATER BLOCK COMPATIBILITY
This CPU liquid cooling unit is pre-assembled for use with modern
Intel desktop-socket type motherboards. By default (out of the box)
this water block supports the following CPU sockets:
- Intel® Socket LGA-115x / LGA-1200
- Intel® Socket LGA-2066/LGA-2011(-3)
- AMD® Socket AM4*
*requires replacing the Intel® mounting plate with an AMD® one.
This product is also fully compatible with AMD® AMx/FMx
sockets but requires a user to replace factory installed Intel
mounting plate with an AMD® one. The following sockets
are then compatible:
- AMD® Socket AMx
- AMD® Socket FMx
The AMD Mounting kit with a mounting plate is already enclosed
inside this Kit!

STEP 2
Cleaning the CPU: Wipe the CPU’s contact surface with a
nonabrasive cloth or Q-tip (as shown in the image).
Applying Thermal Compound: On the clean CPU IHS - Integrated
Heat Spreader, apply a blob or line of enclosed thermal compound
(see sample image on the left).
EK recommends the quantity of about two rice grains of
thermal compound. There is no need to cover the whole
IHS. Applying too much thermal grease will disrupt
cooling performance!
LGA20113 SOCKET MOTHERBOARDS
STEP 1
Prepare the foil bag with the mounting mechanism that is enclosed
with the CPU water block.
Install four (4) specific LGA 2011 M3 thumb screws into four threaded
stubs on the LGA 2011 socket’s integrated latch mechanism (ILM).
The screws are to be installed using no tools (i.e., pliers).
It is recommended to remove the motherboard from the
chassis before proceeding with the CPU water block
installation due to space constraints in various PC cases.

Remove the sticker from the water block cold plate.
Align the water block over the mounting screws on the LGA 2011(-3)
motherboard with a pre-installed CPU.
Before proceeding with installation, it is mandatory to remove
the protective foil from the backside of the water block.
Place an enclosed compression spring and a thumb nut over
each M3 thumb screw. Start fastening two thumb nuts at a time,
preferably in a cross pattern, but do not tighten them fully until all
four are partially screwed in. Then - using your fingers only - screw
in all four thumb nuts until you reach the end of the thread.

The installation of the CPU water block is now complete.
With EK-Supremacy Classic series water blocks, it is
mandatory to use the port closest to the center of the water
block as the INLET port. Mixing these ports up may result in
poor thermal performance of the water block.

STEP 2
Preparing the Backplate Rubber Gasket
The enclosed rubber gasket is an essential part of the backplate and
mounting system, and therefore must be used every time you install
this water block on the motherboard.

STEP 4
Install four (4) M3 thumb screws into your motherboard. It is mandatory
to put a plastic washer underneath each M3 thumb screw. Tighten the
screws to the metal backplate until you reach the end of the thread.
Using tools (i.e., pliers) is not recommended.

Install the backplate rubber gasket and place the metal backplate
for Intel® LGA 115x/1200 socket to the back of your motherboard
ribbed side up (facing away from the motherboard). Align the holes
on the motherboard with holes on the rubber gasket and backplate.
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
with household scissors.
Using one hand, carefully rotate the motherboard assembly with the
front side facing up while holding the backplate and rubber gasket in
place with the other hand.

STEP 6
Align the water block over the mounting screws on the LGA
115x/1200 motherboard with a pre-installed CPU.
Before proceeding with installation, it is mandatory to remove
the protective foil from the backside of the water block.
Place an enclosed coiled spring and a thumb nut over each M4
thumb screw. Start fastening two thumb nuts at a time, preferably in
a cross pattern, but don’t tighten them fully until all four are partially
screwed in. Then – using your fingers only – screw in all four thumb
nuts until you reach the end of the thread.

Replace the factory-installed Intel® mounting plate with the AMD®
one. You will feel the mounting plate locking into position when
placed correctly onto the top.
Reseat the O-ring gasket into the gap between the mounting plate
and water block top.
Pay special attention to the orientation of the copper base.
It should be placed as shown in the picture.
Reinstall the M4x14 screws and use the 2.5mm Allen key in the
clockwise direction to screw them in.

STEP 1
Replacing the Mounting Plate
Place the water block on an even surface and, using the 2.5mm Allen
key in the counter-clockwise direction, remove four M4x14 DIN 7991
screws attaching the copper base to the top.

STEP 3
If already installed, please remove themotherboard from the computer
case. Place it on an even surface with the front facing downward.
STEP 4
Removing the Original Hold-Down Clamps
Using a Philips head screwdriver, remove the four UNC 6-32 screws
securing the original plastic hold-down clamps around the socket
(as shown in the picture). You can use the factory backplate for
mounting the EK-Supremacy Classic water block.

Applying thermal compound: EK recommends a blob or line
method for applying the enclosed thermal compound to the CPU heat
spreader (see sample image).
The quantity of about two rice grains of thermal
compound is just about right. There is no need to cover
the whole IHS. Applying too much thermal grease will
disrupt cooling performance!
STEP 6
Align the water block with the pre-installed mounting screws on the
AMD® socket motherboard.
Before proceeding with installation, it is mandatory to remove
the protective foil from the backside of the water block.
