Safety Precautions
Before you start using this product, please follow these basic guidelines:
Check the component list and condition of the product before
installation. If you encounter a problem, contact the vendor
where you purchased the product to get a replacement or a
refund.
EK is not responsible for any damages due to external causes,
including but not limited to: improper use, problems with
electrical power, accident, neglect, alteration, repair, improper
installation, and improper testing.
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).
This product is an All-In-One liquid cooling solution.
Disassembling it and combining it with parts other than EK
products may lead to warranty loss.
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.

INSTALLING THE GPU WATER BLOCK AND BACKPLATE
FAN SPLITTER HUB
To install the water block to your graphics card, follow the instructions
in the link below:

General Characteristics:
- 3x 4-Pin PWM Fan Header (Molex KK 254 Standard)
- 1x 4-Pin PWM Pump Header (Molex KK 254 Standard)
- 1x 2-Pin Tach/PWM Header (Molex KK 254 Standard)
- 1x 2-Pin Power Header (Molex Mini-Fit Standard)
- 1x Power LED Indicator Diode (Red) - Rectified PWM Input
- Uniform PWM Control on All Headers
All the elements that need electricity to run are connected to the fan
splitter hub, located on the back of the unit.
This fan splitter hub contains three 4-pin PWM fan
headers for three fans and one pump.
A 2-pin header is used to connect the hub to the motherboard CPU
fan header to allow the speed regulation of both fans and the pump.
The 2-pin PCI Express Mini-Fit power header is used to provide
power for the AIO unit.

ELECTRICAL CONNECTIONS Option 1
CONNECTING THE HUB TO THE POWER
SUPPLY
STEP 1
Take the enclosed power cable and plug the 2-pin PCI Express Mini-
Fit power connector into the fan splitter hub.
STEP 2
Use the SATA POWER connector and plug it into the female
connector found on the main power supply.
CONNECTING THE HUB TO THE MOTHERBOARD
To obtain the PWM fan speed control, you must follow these steps:
STEP 3
Take the enclosed connection cable and plug the 2-pin cable
connector into the fan splitter hub.
STEP 4
Use the 4-pin connector and plug it into the male connector header
located on the motherboard.
Always use a CPU fan header. On the majority of
motherboards, these headers offer the best PWM
regulation.

ELECTRICAL CONNECTIONS Option 2
CONNECTING THE PUMP DIRECTLY TO THE
MOTHERBOARD FAN HEADER
If you want to control the speed of the pump and fans separately, you
should follow these steps:
STEP 1
Disconnect the pump cable from the fan splitter hub. You need to
remove cable ties to do so.
STEP 2
Connect the pump’s connector to the CPU fan header (preferably)
on the motherboard.

AIO UNIT ORIENTATION LIMITATIONS
CAUTION: The unit’s orientation is critical since incorrect
installation can lead to poor cooling performance and
premature unit failure.

STEP 1
STEP 2
INSTALLING THE AIO UNIT
STEP 1
Mounting the AIO unit into your PC chassis requires special
attention. You will need eight fan mounting screws and a Phillips
head screwdriver.
STEP 2
The AIO unit’s position depends on the size, fan mounting holes, and
hardware you have installed inside your chassis. You must make sure
that the unit fits into the chassis. Usually, the cases come with pre-
drilled standard fan mounting holes, and you should look for holes
that have 105mm spacing (for standard 120mm cooling fans).
