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,
or 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.
Hold the water block and motherboard and turn them upside down.

STEP 2
After placing the water block, the Backplate must be attached to 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 the 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 three (3) M2 x 2.5 screws in the holes of
the water block and tighten them.
EK recommends using the EK-Loop Torque Screwdriver - 0.6Nm:

FITTINGS AND TUBING
STEP 1
Screw-in two (2) G1/4 threaded male fittings. Attach the liquid-
cooling tubes and connect the water block to the cooling loop.
Tighten the fittings in a clockwise direction until the gasket
underneath is compressed.
EK recommends using EK fittings with all EK water blocks.
Do not forget to plug the remaining two openings with
enclosed EK-Plug G1/4 or its equivalent.
CAUTION: When using connectors other than EK fittings,
pay special attention to the length of the fittings’ male G1/4”
thread – 5 mm is the maximum G1/4” thread length allowed!

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.
