CPU WATER BLOCK
EK-Classic CPU Water Block
115x /20x x D-RGB

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!
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 liquid cooling systems, and mandatory for nickel plated
water blocks!
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!

- EK-CPU Supremacy Classic D-RGB – Nickel + Plexi CPU
water block.
- Mounting Kit Classic - Intel:
• Mounting Screw CPU Classic - 115X (4 pcs)
• Mounting Screw CPU Classic - 20XX (4 pcs)
• Mounting Spring (4 pcs)
• Mounting Nut CPU Classic (4 pcs)

INSTALLING THE WATER BLOCK
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.

STEP 3
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.

STEP 4
Tighten the fitting barbs in clockwise direction until the gasket
underneath is compressed.
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.

LGA115x SOCKET MOTHERBOARDS
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.

Install four (4) M3 thumb screws onto your motherboard. It is mandatory
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.

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 coiled spring and thumb nut over each of the M4
thumb screws.. 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.

CONNECTING THE D-RGB LED STRIP
D-RGB LED Connector
STEP 1
Connect the 3-pin D-RGB LED connector from the Water block’s LED
light into the D-RGB (Addressable) HEADER on the motherboard.
The LEDs will work if the pin layout on the header is as follows: +5V,
Digital, Empty, Ground.
Please ensure that the arrow indicated on the connector
is plugged into the +5V line, as indicated on your
motherboard. If you connect LEDs to the 12V RGB header,
it will damage them.
