USER GUIDE
GPU WATER BLOCK
EK-PRO
GPU WB RTX A100 80GB

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 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 attention to the following steps in order to install
the EK-Pro GPU RTX A100 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

- 8 -
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 water
block, 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
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!
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
For this Step, you will need:
M 2.5 PVC Washer
(8 pcs)
M2.5 x 4 AX1
Screw (8 pcs)
4 mm
STEP 2
STEP 2
ATTACHING THE WATER BLOCK
Use eight (8) 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 damage to the GPU.
The screws must be present on the places marked below:
Phillips Head
Screwdriver

STEP 4bSTEP 4a
STEP 4
Secure power cable with mounting it into included inox power
adapter.
STEP 4a
Stick the two included plastics pads (M3) on to inox power addapter
as shown on picture.
STEP 4b
Insert 8-pin power connector in to the inox adapter. Pads on the
power adapter must be alligned with openings in inox power adapter.
Pay attention to the orietation of the latch on connector.
For this Step, you will need:
M3x6
SCREW
Screw M3x6 DIN 7991
(2x) 9029
Allen Key 2mm
(1x) 8901
STEP 4c
STEP 4c
Fasten a inox power adapter to the water block with two M3x6
screws. The power cables is needed to be twistand bend a bit in
order to fit them in.

- 11 -
CHECKING THE CONTACT IN CASE OF HIGH TEMPERATURES
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/.
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 PCI express 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.

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

In case you need assistance or wish to order spare parts or a new
mounting mechanism, please contact:
