DOZEN GOOD ADVICES FOR THE NEWCOMERS
1. In order to lower shipping costs, we have decided to enclose only
the coolant concentrate for liquid cooling. Therefore you need
to provide 1 liter (1L) of distilled water. You can get it at every gas
station or supermarket.
2. Never run this system on tap water and always use the
enclosed cooling concentrate in the correct 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. The Reservoir must be positioned above the height level of the
water pump in order for the liquid to flood the pump which is
crucial for the first start-up.
5. Generally, for optimal performance, the Reservoir must be
positioned before the pump in the water loop.
6. It is best practice to do a proper leak test before using your computer.
7. If you spot any leaks, turn off the power immediately!
8. Optimize tubing length in order to prevent excessive bending
and kinking of the tubing.
9. Never let your pump run dry. If this is happening for a prolonged
period of time you may risk destroying the water pump’s bearing,
rendering the pump useless.
10. You are encouraged to periodically clean the radiator assembly
as it will collect dust over time. This is best done with a soft
wide tip brush and vacuum cleaner. See chapter ‘General liquid
cooling parts 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 Intel® mounting plate with 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 AMD® one. The following sockets are
then compatible:
- AMD® Socket AMx
- AMD® Socket FMx
AMD Mounting kit with mounting plate is already enclosed inside
this Kit!

STEP 2
Cleaning the CPU: Wipe the CPU’s contact surface (by using non–
abrasive cloth or Q-tip, as shown on the sample photo).
Applying thermal compound: EK recommends blob or line
method of applying the enclosed thermal compound to the CPU
heat spreader (IHS) - see sample photo on the right.
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!
LGA20113 SOCKET MOTHERBOARDS
STEP 1
Prepare the foil bag with mounting mechanism, which is enclosed
with the CPU water block delivery.
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 form the
PC chassis before proceeding with installation of the CPU
water block because of the space constraint limitations of
various computer cases.

Take the waterblock and remove the sticker from the cold plate.
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 M3
thumb screw. Start fastening two thumb nuts at a time, preferably
in a 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.

The installation of the CPU water block is now complete.
With EK-Supremacy Classic 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 1
If already installed, please remove the motherboard from your
computer and place it on an even surface with the front facing down.
STEP 2
Preparing backplate rubber gasket
The enclosed rubber gasket is an essential part of the backplate and
mounting system and must be used every time you install this water
block on your motherboard.
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.
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.
Carefully rotate motherboard assembly with front side facing up
with one hand while holding the backplate and rubber in place with
the other hand.

to put 0.7mm plastic washer underneath each of the M3 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.
