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 website at www. ekwb.com for updates.
Before installation of this product please read the 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 thoroughly before beginning
the installation process!
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-Cryo Fuel coolants.
Make sure to thoroughly bleed air out of your water block, or
you will not reach optimal performance.

Thermal Grease
STEP 1
Apply the enclosed EK-TIM Ectotherm thermal grease (thermal
compound) on the CPU heat spreader – IHS – as shown in the
image. The layer of the thermal compound must be thin and even
in thickness over the entire surface of the IHS.
The excessive or uneven application of thermal grease
may lead to poor performance!
STEP 1
APPLYING THERMAL COMPOUND
For this step, you will need:
ATTACHING THE WATER BLOCK
STEP 1
Carefully place the CPU water block onto the motherboard and align
four (4) mounting screws with four (4) holes on the motherboard.

STEP 2
After placing the water block, the Backplate must be attached on the
backside of the motherboard using Allen Key 2.5 mm (shown in the image).
While holding the water block and the motherboard with one hand,
align the Backplate with Mounting Screws of the water block. Turn
the mounting nuts using Allen Key 2.5 mm in the clockwise direction
according to the numerical order shown in the image. Do not tighten
fully until all of the nuts are partially screwed in. After the Backplate
is tightened, put five (5) M2x2.5 screws and washers in holes of the
water block and tighten them.
EK recommends using the EK-Loop Torque Screwdriver - 0.6Nm:

CONNECTING THE D-RGB LED STRIP
STEP 1
Plug the 3-pin connector of the distribution plate D-RGB LED
light to the D-RGB HEADER on the motherboard. The LED 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 put the LED Diode to the 12V RGB HEADER you
can damge the LEDs. Failure to do so will damage your
motherboard or LED strip.
STEP 1
D-RGB HEADER
RGB HEADER
To make sure the installation of EK components was successful, we
recommend you perform a leak test for 24 hours. When your loop
is complete and filled with coolant, connect the pump to a PSU
outside of your system. Do not connect power to any of the other
components. Turn on the PSU and let the pump run continuously.
It is normal for the coolant level to drop during this process as air
collects in the distribution plate. Inspect all parts of the loop, and
in the eventuality that coolant leaks, fix the issue and repeat the
testing process. Ensure that all hardware is dry before the system is
powered on in order to prevent any damage.
TESTING THE LOOP

Our products are warranted against defects of materials and
quality for a period of 24 months, starting with the date of delivery
to the end-user. During this period, products will be repaired
or have parts replaced at our discretion, provided that 1) the
product is returned to the agent from whom it was purchased;
2) the product has been purchased by the end-user and has not
been used for commercial purposes; 3) the product has not been
misused, handled carelessly, or used in a manner other than the
way described in the instructions manual. This warranty does not
confer rights other than those expressly set out above and does not
cover any claims for consequential loss or damage. This warranty
is offered as an extra benefit and does not affect your statutory
rights as a consumer. This warranty is voided if the product
comes in contact with aggressive UV additives or other improper
liquids. EK water blocks are sealed with a warranty-voiding circular
label, proving the water block has withstood a pressure leak test.
Removing the label will void the leak-free guarantee, but not the
guarantee on the product itself. Any other RMA issues can be
reported to EK Customer Support at www.ekwb.com/support
for further analysis.
