Fluid Gaming EK-AC GEFORCE RTX 3080/3090 D-RG User manual

EK-AC GEFORCE RTX 3080/3090 D-RGB
USER GUIDE

/ 2 /
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.
This product is made from aluminum and can be only used
with other aluminum liquid cooling components, such as Al
fittings, water blocks and radiators. Mixing aluminum with
copper and brass products can cause galvanic corrosion
of the metal and render liquid cooling equipment useless.
Such misuse is not covered by warranty.

PREPARING YOUR 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 atten-
tion to the following steps in order to install the EK-AC GEFORCE RTX
3080/3090 D-RGB 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 com-
pound 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:

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.

APPLYING THERMAL COMPOUND
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 1
STEP 2
M2.5 x 4 AX1 SCREW
M2.5 PVC WASHER
For this Step, you will need:
M 2.5 PVC Washer
(11 pcs)
M2.5 x 4 AX1
(11 pcs)
Phillips Head
Screwdriver
4 mm
STEP 2
ATTACHING THE BLOCK TO THE GRAPHICS CARD
Use eleven (11) M2.5 X 4 AX1 screws and 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 the damage to the GPU. Always use a plastic washer
under each screw!

INSERTING THE GRAPHICS CARD INTO THE CHASSIS
CHECKING FOR CONTACT
STEP 1
If necessary, temporarily remove the water block to check for uniform sur-
face 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 previ-
ous section to re-attach the block.
In case you fail to obtain good contact, please check again or
contact our support service at www.ekwb.com/support.
STEP 1
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.

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 spe-
cial attention to the length of the fittings’ male G1/4” thread - 5 mm is
the maximum G1/4” thread length allowed!

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!

/ 13 /
To make sure the installation of EK components was successful, we rec-
ommend 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.
