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 correct ratio.
3. Never use alcohol, alcohol derivatives or alcohol based solvents in the
system. Using alcohol might result in permanent damage to liquid cooling
KIT components, especially acrylic parts of the system.
4. Reservoir must be positioned above the height level of the water pump in
order for liquid to flood the pump which is crucial for the first start-up.
5. Generally, for optimal performance, the Reservoir must be positioned be-
fore the pump in the water loop.
6. Generally, for optimal performance, the CPU water block should be right
after the Radiator in the water loop.
7. Generally, for optimal performance, the Pump should be positioned before
the Radiator in the water loop.
8. It is best practice to do a proper leak test before using your computer.
9. If you spot any leaks, turn off the power immediately!
10. Optimize tubing length in order to prevent excessive bending and kinking
of the tubing.
11. Never let your pump run dry. If this is happening for a prolonged period
of time you may risk destroying water pump’s bearing, rendering the pump
useless.
12. You are encouraged to periodically clean the radiator assembly as it will
collect dust over time. This is best done with soft wide tip brush and vacu-
um 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-775
- Intel® Socket LGA-115x
- Intel® Socket LGA-1366
- Intel® Socket LGA-2011(-3)
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
Narrow server type LGA-2011 is not supported by default – a Mounting plate
Supremacy LGA-2011 Narrow ILM (EAN: 3830046990600) is mandatory
to install this water block on narrow server type LGA-2011 motherboards.
Replacing the mounting plate requires disassembly of the water block.

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 M4 thumb screws into four M4 threaded stubs
on the LGA-2011 socket 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.
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: EK recommends blob or line method of applying
the enclosed EK-TIM Ectotherm thermal compound to the CPU heat spreader
(IHS) - see sample photo on 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!

INSTALLING THE RADIATOR AND FANS
OPTION #1:
INSTALLING THE RADIATOR AND
FANS
STEP 1
Install the fans on the radiator.
Ideally, the radiator should either:
A) receive the coldest air possible (by placing the radia-
tor on the air inlet) or
B) serve as an overall hot air exhaust (by placing the
radiator on the exhaust).
The latter results in overall decrease of temperature
throughout the entire computer chassis but also leads to
slightly higher liquid temperatures. A reversed air flow is vi-
able option but one should always strive to achieve unidi-
rectional flow of air throughout the chassis.
Take the four UNC 6-32x30mm screws for each fan and screw them
in. Use enclosed Allen key to tighten the screws in clockwise direction.
STEP 2
Prepare your suitably-sized PC chassis for installation of radiator
unit. The position of the unit in the chassis depends on the size, fan
mounting holes and the hardware you have installed. You must make
sure that the unit fits into the chassis. Usually the chassis have stand-
ard fan mounting holes pre-drilled so you should look for holes with
spacing of 105mm. (A standard computer cooling 120mm fan)
STEP 3
Align the holes on the radiator with the ones on the PC chassis.
Take the four UNC 6-32x5mm screws for each fan and guide them
through the holes on the chassis to screw them into the threaded holes
on the radiator. Tighten them in clockwise direction using Allen key.

INSTALLING THE PUMP-RESERVOIR UNIT
STEP 1
The KIT comes with combined pump and reservoir unit with pre-
installed anti-vibration decouplers.
Take the unit and place it on the EK-UNI Pump Bracket (120mm
Fan).
Secure it from the bottom side using four M4x4 screws and PVC
washers. Tighten them in clockwise direction using enclosed
2,5mm Allen key.
This unit can be installed anywhere where there is a
50x50mm square mounting hole pattern on the chas-
sis without using any pump bracket.
STEP 2
The position of the unit in the chassis depends on the fan mount-
ing holes and the hardware you have installed. Usually the chassis
have Pre-drilled standard fan mounting holes on the bottom one
should look for holes with spacing of 105mm. (A standard com-
puter cooling 120mm fan).
Alternatively you can drill four Ø4,5mm holes using
electric power drill to the most suitable place on the bot-
tom of your computer chassis.
Put four M4x6 DIN7984 screws through the holes on the UNI
pump bracket from the upper side.
