USER GUIDE
GPU WATER BLOCK
EK-Quantum
Vector FE RTX 3090 D-RGB + Backplate

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.

PREPARING THE GRAPHICS CARD
STEP 1
REMOVING THE STOCK COOLER
Place your graphics card on the flat surface and carefully remove the
stock cooler. Do not forget to unplug all the LED and fan connectors.
Pay attention to the following steps in order to install the EK-Quantum
Vector FE RTX 3090 water block onto the graphics card.
STEP 2
CLEANING THE PCB
Carefully detach the original stock cooler after removing all screws
that are securing it to the board. Wipe off the remains of the original
thermal compound using a nonabrasive cloth or Q-tip, as shown
in the sample image, until the components and circuit board are
completely clean. EK recommends the use of denatured alcohol for
removing TIM leftovers.
STEP 2

- 8 -
STEP 1
Your 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.
You must remove the protective foil from both sides of the
thermal pad before installation.
Replacement thermal pads:

Thermal Grease
STEP 1
Apply the enclosed EK-TIM Ectotherm 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!

the graphics card. During this process, make sure you have aligned
mounting holes of the PCB with holes of the water block (the same
applies to other tops).
Pay attention not to use too much force when pressing the
block down to the PCB since chip dies are prone to cracking.

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 PCIexpress expansion slot.
Please bear in mind that your graphics card is very likely 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.
CHECKING FOR CONTACT
If necessary, temporarily remove the water block to check for uniform
surface contact between the block and components. Pay special
attention to the VRM section of the graphics card. Check whether
the water block makes contact with the intended integrated circuit.
Then repeat Steps from the previous section to re-attach the block.
In case you fail to obtain good contact, please check
again or contact our support service at
https://www.ekwb.com/customer-support/.

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 to the LED strip or the header itself!
STEP 1

INSTALLATION OF FITTINGS AND TUBING
STEP 1
Screw-in two (2) G1/4 threaded male fittings. Attach the liquid
cooling tubes and connect the water block(s) to the cooling loop.
Do not forget to plug the remaining two openings with
enclosed EK-Plug G1/4 or its equivalent.
You can use any opening as an inlet/outlet port.
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!

To make sure 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 of 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.
