USER GUIDE
EK-Quantum
Vector FE RTX 3090 D-RGB 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 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.
EK only guarantees compatibility with included EK-brand
thermal pads. The installation process, cooling performance,
and block contacts are tested exclusively with EK-brand
thermal pads. Listed thermal pad thicknesses apply only to
those included in the package.
EK does not guarantee compatibility with aftermarket
alternatives for thermal interface material.

For this Step, you will need:
PREPARING THE 3090 FE WATER BLOCK
STEP 1
Unscrew the three (3) M3x12 DIN7991 screws and remove the backplate
cover, as shown in the image..

For this Step, you will need:
STEP 2
After removing the backplate cover, four (4) backplate screws
needs to be removed. Detach the backplate as shown in the image.
Preinstalled thermal pads on the PCB also must be
detached. After removing the thermal pads, pre-applied
thermal grease also needs to be removed using a
nonabrasive cloth or Q-tip. EK recommends the use of
denatured alcohol for removing TIM leftovers.

STEP 3
EK-Quantum Vector FE 3090 Active Backplate comes with its own
terminal, meaning the original terminal on the EK-Quantum Vector
FE 3090 water block must be removed.
In case the EK-Quantum Vector FE 3090 water block is
already filled with coolant, empty the contents of the
water block before continuing with this step. Be careful
that the coolant that remained in the water block does
not contact the GPU!
For this Step, you will need:

Your Active Backplate comes with thermal pads that must be cut into
smaller pieces to cover all the VRM components. EK has included
more than enough thermal pads to complete the following Step(s).

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.
