This product is intended for installation by expert users only. Please
consult with a qualified technician for installation. Improper installation
may result in damage to the equipment. EK 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.
Prior to the 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:
Carefully read the manual before beginning with the
installation process!
Remove your motherboard from the chassis for the safest
mounting process and to prevent damaging your CPU and/or
motherboard’s 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.

Backplate Screws
STEP 2
STEP 2
On the backside of the motherboard, six (6) additional screws
need to be removed, as marked in the picture. Once these screws
are removed, you can carefully detach the backplate from the
motherboard. The backplate can be reused after mounting the
water block.

REMOVING THE PLASTIC I/O COVER
STEP 1
Unscrew one (1) standoff and two (2) screws to remove the plastic
I/O cover. This plastic cover can be reused once you’ve installed the
water block.
For easier installation of the water block, we recommend you
disconnect the LED connector first.

CUTTING AND PLACING THERMAL PADS
Your monoblock comes with thermal pads that need to be trimmed
to fit the voltage regulation area (MOSFET) on the motherboard’s
circuit board.

CAUTION: Remove the protective foil from both sides of a
thermal pad before installation.

APPLYING THERMAL COMPOUND
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!
