USER GUIDE
GPU WATER BLOCK
EK-Quantum
Vector² Strix/TUF RTX 4090 D-RGB

Please note the installation of the product is intended to be undertaken
by an adequately trained and experienced person. You are installing the
product at your own risk. If you are not properly trained or experienced
or feel unsure about the installation procedure, please refrain from
installing the product yourself and contact our tech support for
assistance. We disclaim our liability for any damages to the product as
well as incidental, consequential, or indirect damages incurred due to
improper or inappropriate installation.
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).
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-CryoFuel
coolants! To reach optimal performance, make sure to
thoroughly bleed the air out of your water block!

PREPARING THE GRAPHICS CARD
REMOVING THE STOCK COOLER
ASUS TUF GAMING GEFORCE RTX 4090
Important! Before starting, make sure to have a clean, flat
surface to work on. It is recommended to put foam or soft
material to lay the graphics card on.
STEP 1
First, remove eight (8) screws from the backside of the Stock cooler
(using Phillips head screwdriver).
STEP 2
Unscrew three (3) screws from the I/O Bracket (using Phillips head
screwdriver). Unplug the connectors in order to remove the stock
cover from the GPU PCB.
STEP 1
STEP 2

- 9 -
STEP 3
From the front side of the GPU, an additional two (2) screws must be
removed (using Phillips head screwdriver). Detach the GPU Backplate.
STEP 4
Rotate the GPU and unscrew four (4) Screws from the retention
bracket (using Phillips head screwdriver). Remove the bracket and
Stock Cooler from the GPU PCB.

PREPARING THE WATER BLOCK FOR INSTALLATION
STEP 1
Unscrew seven (7) Screws AX1 M2.5 x 8 mm. Remove the backplate
together with the Screws and backplate standoffs. Standoffs must stay
on Screws AX1 M2.5 x 8 mm. Remove the PCB cardboard. Save the
removed parts for later steps.
Do not remove standoffs from screws! In case the
standoff detaches from the screw, replace it with a
spare one. When replacing the standoff make sure
that you screw it on the AX1 M2.5 x 8 screws. Do not
push the standoff onto the screw AX1 M2.5 x 8 mm.

STEP 1
The GPU water block comes with thermal pads that have to be cut
into smaller pieces to cover all the VRM components, such as COILs,
MOSFETs, and drivers.
Remove the protective foil from both sides of the thermal
pad before installation.
Replacement thermal pads:

Thermal Grease
STEP 1
Apply the enclosed thermal grease (thermal compound) on the GPU
heat spreader – IHS – as shown in the image. The layer of the thermal
compound must be thin and even over the entire surface of the IHS.
The excessive or uneven application of thermal grease
may lead to poor performance!
APPLYING THERMAL COMPOUND
For this step, you will need:
STEP 1

ATTACHING THE WATER BLOCK (Option 1: GeForce RTX 4090 ROG Strix)
STEP 1
Carefully position the water block with preinstalled standoffs on the
graphics card. During this process, make sure you have aligned the
mounting holes of the PCB with the holes of the water block.
Pay attention not to use too much force when pressing
the block down to the PCB since chip dies are prone
to cracking.
Before attaching the PCB to the Water Block, make sure
all the Thermal Pads are placed correctly!
STEP 1
STEP 2
Use seven (7) M2.5 x 4 AX1 Screws and PVC washers to tighten
the PCB on the water block. Tighten the screws evenly using the
Phillips-head screwdriver. EK recommends you start tightening the
screws around the GPU core first, and then continuing outward to
prevent damage to the GPU. After attaching the water block, three
(3) saved Factory provided I/O Bracket screws can be reused.
For this step, you will need:
M2.5 x 4 AX1 SCREW

Carefully position the water block with preinstalled standoffs on the
graphics card. During this process, make sure you have aligned the
mounting holes of the PCB with the holes of the water block.
Pay attention not to use too much force when pressing
the block down to the PCB since chip dies are prone
to cracking.
Before attaching the PCB to the Water Block, make sure
all the Thermal Pads are placed correctly!

Screws must be present in the places marked on the picture.
STEP 2
Use seven (7) M2.5 x 4 AX1 Screws and PVC washers to tighten the
PCB on the water block. Tighten the screws evenly using the Phillips-
head screwdriver. An additional one (1) M2.5 x 6 AX1 Screw must be
secured with an M2.5 Nut.
EK recommends you start tightening the screws around the GPU core
first, and then continuing outward to prevent damage to the GPU.
After attaching the water block, three (3) saved Factory provided I/O
Bracket screws can be reused.

screws evenly.
Before attaching the backplate, make sure all the Thermal Pads
are placed correctly!
Do not use excessive force!
INSERTING THE GRAPHICS CARD INTO THE CHASSIS
Carefully lift your graphics card with the installed water block and
insert it into your PC’s motherboard PCI Express expansion slot.
Please keep in mind that your graphics card is heavier than before it
was equipped with the water block.
You need to be very careful when handling the graphics
card. Avoid all unnecessary manipulation of the water block
assembly that might damage your card or water block.

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.
Incorrect installation or installation to a wrong header can
damage the LED strip or the header itself!

FITTINGS AND TUBING
Screw in two (2) G1/4 threaded male fittings. Attach the liquid
cooling tubes and connect the water block to the cooling loop.
Do not forget to plug the remaining two openings using
the enclosed EK-Plug G1/4 or its equivalent.
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!

Our products are warranted against defects of materials and quality
for a period of 24 months, starting with the date of delivery to the
end-user. During this period, products will be repaired or have parts
replaced at our discretion, provided that 1) the product is returned
to the agent from whom it was purchased; 2) the product has been
purchased by the end-user and has not been used for commercial
purposes; 3) the product has not been misused, handled
carelessly, or used in a manner other than the way described in
the instruction’s manual. This warranty does not confer rights
other than those expressly set out above and does not cover any
claims for consequential loss or damage. This warranty is offered
as an extra benefit and does not affect your statutory rights as a
consumer. This warranty is voided if the product comes in contact
with aggressive UV additives or other improper liquids. EK Water
blocks are sealed with a warranty-voiding circular label, proving
the water block has withstood a pressure leak test. Removing the
label will void the leak-free guarantee, but not the guarantee on
the product itself. Any other RMA issues can be reported to EK
Customer Support at www.ekwb.com/support for further analysis.
WARRANTY
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 the 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.
TESTING THE LOOP

In case you need assistance or wish to order spare parts or a new
mounting mechanism, please contact:
https://www.ekwb.com/customer-support/
For spare parts orders, refer to the page with “TECHNICAL
SPECIFICATIONS AND WATER BLOCK PARTS” where you can find
the EAN number of each part you might need.
Include the EAN number with quantity in your request. Mounting
Mechanism EAN can be found under “BOX CONTENTS”
