This product is intended for installation by expert users only. Please consult
with a qualified technician. Improper installation may result in damage to
your equipment. EK assumes no liability whatsoever, expressed or implied,
for the use of this product or its installation. The following instructions are
subject to change without notice. Please, read the manual carefully before
beginning with the installation process. For updates, you can visit our
official website www.ekwb.com.
Before you start using this product please follow these basic guidelines:
Carefully read the manual before beginning with the installation
process.
Remove your graphics card from the computer for the safest
mounting process to prevent any possible damage to your GPU or
its circuit board (PCB).
EK Fittings require only a small amount of force to screw them
firmly in place since the liquid seal is ensured with the rubber O-ring
gaskets.
The use of quality market-proven corrosion-inhibiting coolants is
always strongly recommended for any liquid cooling system.
Do not use pure distilled water as a cooling liquid! For best results,
EK recommends the use of EK-CryoFuel Coolants.
Make sure to bleed air out of your water block thoroughly in order to
reach optimal performance.

STEP 1
CHANGING THE COLDPLATE
STEP 1
Cleaning the CPU: Wipe the CPU’s contact surface with a non-
abrasive cloth or Q-tip.
STEP 2
Applying Thermal Compound: Apply the enclosed thermal
grease (thermal compound) on the CPU heat spreader (IHS) as
shown in the image.
There is no need to cover the whole IHS – applying too much thermal
grease will have a negative impact on the cooling performance!

STEP 3
Before proceeding with installation, it is mandatory to remove
the protective foil from the backside of the water block.
Placing the Water Block on the Motherboard: Place your
motherboard on an even surface and remove the Mounting
Mechanism from the plastic bag.
Install four (4) Standoffs tightly into the ILM Heat Sink studs by hand.
Using pliers or similar tools is not recommended. After securing the
Standoffs, position the CPU Water Block onto the Standoffs.

STEP 6
Installing Fittings and Tubing: Screw-in two (2) G1/4 threaded
male fittings. Attach the tubes and connect the CPU water block to
the liquid cooling loop.
EK recommends using EK fittings with all EK water blocks.
CAUTION: When using connectors other than EK
fittings, pay special attention to the length of the fittings’
male G1/4” thread – 5mm is the maximum G1/4” thread
length allowed!
By default, the inlet port is placed on the left side.
