USER GUIDE
EK-Quantum
Vector Strix RTX 3080/3090 Active Backplate

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.

INSTALLING THE ACTIVE BACKPLATE
STEP 1
PREPARING THE GRAPHICS CARD
First, complete the installation of your EK-Quantum Vector Strix RTX
3080/3090 water block according to its installation manual. In case
the water block is already installed, remove the six (6) AX1 screws
and their PVC washers, as shown in the image.
Phillips Head Screwdriver
For this Step, you will need:

EK-Quantum Vector Strix RTX 3080/3090 Active Backplate comes
with its own terminal, meaning the original terminal, along with two
(2) 15 x 1 O-rings, on the EK-Quantum Vector Strix 3080/3090 water
block has to be removed.
Unscrew the three (3) M4 x 27 DIN7984 screws and detach the
terminal from the water block.
The procedure of terminal detachment is shown in the image.
Attention!
In case the EK-Quantum Vector Strix 3080/3090 water
block is already filled with coolant, empty the content
of the water block before continuing with this step. Be
careful that the coolant that remained in the water block
does not come in contact with the GPU!

CUTTING AND PLACING THERMAL PADS
Your backplate comes with thermal pads that have to be cut into
smaller pieces to cover all the VRM components. EK made sure to
provide you with more than an adequate quantity of thermal pads to
complete this Step-s.
Replacement thermal pads:
Thermal PAD F 1.0 mm – (120 x 16 mm) – EAN: 3830046996732
Thermal PAD G 1.5 mm – (120 x 24 mm) – EAN: 3830046996787

REMOVING THE TERMINAL METAL PLATE
The Metal plate attached on the Terminal is meant as a precaution,
to secure the two O-rings to prevent them from falling out of their
sockets during transport and handling. Before the installation of
the Active Backplate, this metal plate has to be removed. Unscrew
the three (3) M4 x 27 DIN7984 screws with the provided 2.5 mm
Allen Key shown on the picture. Keep the screws as they will be
needed in the upcoming step, unlike the metal plate which will not
be needed anymore.

ATTACHING THE ACTIVE BACKPLATE
First, make sure the two (2) 15 x 1 O-rings are IN terminal
slots, as shown in the image.
STEP 5

- 13 -
Place the active backplate on the PCB and make sure all holes are
aligned. Position an M2.5 x 8 AX1 screw into each of the six (6)
mounting holes (as shown in the image) and tighten them evenly
with a Phillips head screwdriver.
To avoid using excessive force, you can easily loosen up the three
(3) M4 x 27 7984DIN screws pre-installed on the terminal, but be
careful that two (2) 15 x 1 O-rings remain in their terminal slots.
Also, do not forget to tighten the three (3) loosed M4 x 27 7984DIN
screws back after attaching the Active Backplate
Then, position the three (3) M4 x 27 7984DIN screws that were
detached from the GPU water block terminal into each of the three
(3) mounting holes (as shown in the image) and tighten them evenly
with the provided 2.5 mm Allen Key.
Do not use excessive force!
CAUTION: When placing the Active Backplate on the PCB,
the two inserted 15 x 1 O-rings must remain inside their
STEP 5 terminal slots. Wrongly positioned O-rings can
cause leaks!

STEP 1
Screw-in two (2) G1/4 threaded male fittings. Attach liquid cooling
tubes and connect the water block to the cooling loop.
The pre-mounted terminal is positioned for the optimal flow in the
EK-Quantum Vector Strix RTX 3080/3090 water block and in the
EK-Quantum Vector Strix RTX 3080/3090 Active Backplate. The
terminal can be shifted for 180 degrees but by using it so, the inlet
and outlet ports are changed.
The plugged port is not mentioned to be used as inlet/outlet !
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 – 5 mm is the maximum G1/4” thread length allowed!
CONNECTING THE D-RGB LED STRIP
STEP 1
Plug the 4-pin D-RGB connector from the GPU water block to the
D-RGB Header on your motherboard or controller. The LED strip will
work only if the pin layout on the header is as follows: +5V, Data,
Empty, Ground.
Incorrect installation or installation to a wrong header can
damage the LED strip or the header itself!

TESTING THE LOOP
To ensure the installation of EK components was successful, we
recommend you perform a 24-hour leak test.
When your loop is complete and filled with coolant, connect the
pump to a PSU outside your system. Do not connect power to any
of the other components. Turn on the PSU and let the pump run
continuously.
Inspect all parts of the loop, and in case the coolant leaks, fix the issue
and repeat the testing process. To prevent possible damage, please
ensure that all hardware is dry before the system is powered on.
