EK-Quantum Vector RX 6800/6900 D-RGB - AMD Radeon... User manual

USER GUIDE
GPU WATER BLOCK
EK-Quantum
Vector RX 6800/6900 - AMD Radeon Edition

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
You will need the following tool:
Phillips Head Screwdriver
STEP 1
STEP 1
REMOVING THE STOCK BACKPLATE
Use the Phillips head screwdriver to unscrew the twelve (12) marked
screws. Evenly untighten four (4) retention bracket screws for easier
disassembly. Remove the Backplate and the Retention bracket from
the backside of the GPU.
STEP 2
REMOVING THE STOCK COOLER
Use the Phillips head screwdriver to unscrew the sixteen (16) marked
screws – thirteen (13) from the bottom side and three (3) from the side
of the I/O Bracket. Carefully detach the PCB from the stock cooler and
disconnect all cables connecting the stock cooler to the PCB.
Always remove the stock cooler slowly - it might be firmly
glued to the PCB with thermal pads.

For this Step, you will need:
To remove the I/O Bracket, unscrew all five (5) screws marked in
a diagram. Save the four (4) marked screws for later since you will
need them to mount the new bracket.
Use four (4) stock screws that you saved and one M2.5 X 4 AX1
screw with the M2.5 nut to mount the Single-Slot Bracket.

STEP 3
CLEANING THE PCB
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. After that,
remove all remaining stock thermal pads from the PCB.
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.
Thermal pads:

Once cut to size, thermal pads should be placed on the PCB, as
illustrated below. EK made sure to provide you with more than an
adequate quantity of thermal pads to complete this Step.
Thermal Pad F 1.0mm
Thermal Grease
STEP 1
Apply the enclosed EK-TIM Ectotherm thermal grease (thermal
compound) on the CPU 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!

INSTALLING THE WATER BLOCK
STEP 1
PLACING THE BLOCK ON THE GRAPHICS CARD
This procedure is the same for all full-cover water blocks.
Carefully position the water block with preinstalled standoffs on
the graphics card. During this process, make sure you have aligned
mounting holes of the PCB with holes of the water block (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.

STEP 2
ATTACHING THE WATER BLOCK
Use fifteen (15) M2.5 X 4 AX1 screws and fourteen (14) M2.5
PVC washers. 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.

Position an M2.5X8 AX1 screw in each of the six (6) mounting holes
(as shown in the image) and tighten them evenly with a Phillips
head screwdriver. Do not use excessive force!

INSERTING THE GRAPHICS CARD INTO THE CHASSIS
CHECKING THE CONTACT IN CASE OF HIGH TEMPERATURES
Carefully lift your graphics card with the installed water block and
insert it into your PC’s motherboard PCIexpress 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.
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 the LED strip or the header itself!

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.
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 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 all hardware is dry before the system is
powered on.
TESTING THE LOOP
