USER GUIDE
GPU WATER BLOCK
EK-PRO
GPU WB RTX 30x0

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-Pro GPU WB RTX 30x0 water block onto the graphics card.
STEP 2
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 2

CUTTING AND PLACING THERMAL PADS
Your GPU water block comes with un-cuted thermal pads to cover all
the VRM components, such as COILs, MOSFETs, and drivers. Please
use 1.0mm thick thermal pads which 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.
You must remove the protective foil from both sides of the
thermal pad before installation.
Thermal Pad F 1.0 mm
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!
STEP 1
APPLYING THERMAL COMPOUND
For this Step, you will need:

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.
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
STEP 2
Make sure that three (3) the self-adhesive M2,5 plastic washers are
in place as shown in picture.
Pay attention to the front area, where I/O ports are, those
metal springs may get in the way when inserting, holes on
PCB and block needs to be perfectly aligned!

M2.5 PVC WASHER
STEP 2
To mount the graphics card onto the waterblock, stock cross
backplate needs to be use. Attach it with five (5) M2.5 Washers and
M2.5 X 4 AX1 screws.
STEP 3
STEP 3
Install 1.0mm thick thermal pads on the PCB, as illustrated below
to ensure better connection between graphic card and backplate.
EK made sure to provide you with more than an adequate quantity
of thermal pads to complete this Step.
