USER GUIDE
GPU WATER BLOCK
EK-PRO
GPU WB AMP-Trinity RTX 4090 Ni+Inox

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
Phillips Head Screwdriver
REMOVING THE STOCK COOLER
ZOTAC GAMING GeForce RTX 4090 AMP Extreme AIRO
STEP 1
Using a Philips-head screwdriver, unscrew marked screws to detach
the stock cooler and retention bracket from the GPU PCB. After
removing, carefully unplug all the LEDs and FANs cables.
For this step, you will need:
STEP 2
Phillips Head Screwdriver
STEP 2
From the front side of the GPU PCB, additional two (2) screws must
be unscrewed to remove the I/O Bracket from the GPU PCB. Lastly,
unscrew four (4) backplate screws. Remove the Backplate.
For this step, you will need:

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.

CUTTING AND PLACING THERMAL PADS
STEP 1
The 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.
Remove the protective foil from both sides of the thermal
pad before installation.
Replacement thermal pads:

Once cut to the size, Thermal Pads should be placed on the
coldplate, as shown in the picture.
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

ATTACHING THE WATER BLOCK
STEP 1
For this Step, you will need:
M2.5 x 4 AX1
Screw (8 pcs)
4 mm
STEP 2
M2.5 x 4 AX1 SCREW
STEP 2
Use eight (8) M2.5 x 4 AX1 Screws and tighten the PCB on the
water block. Tighten the screws evenly using the Philips-head
screwdriver. EK recommends you start tightening the screws
around the GPU core first and then continuing outwards to prevent
damage to the GPU.
Phillips Head
Screwdriver
STEP 1
Carefully position the water block with preinstalled standoffs on the
graphics card. During this process, make sure you have aligned the
mounting holes of the PCB with the 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.
Before attaching the PCB to the Water Block, make sure
all the Thermal Pads are placed correctly!

- 11 -
STEP 2
Apply the thermal pads onto the Backplate as shown in the image.
INSTALLING THE BACKPLATE
STEP 1
After attaching the water block, a few more thermal pads needs to
be cut into smaller pieces to cover all the necessary componets.
EK made sure to provide with more than an adequate quantity of
thermal pads to complete this step.
Remove the protective foil from both sides of the thermal
pad before installation.
Replacement thermal pads:
Thermal Pad F 2.0 mm – (120 x 16 mm) EAN: 3830046996756

STEP 3
ATTACHING THE BACKPLATE
Use six (6) M2.5 x 7 AX1 screws. Tighten the screws evenly using
the Phillips head screwdriver.
The screws must be present on the places marked below:
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
