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.

STEP 1

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:

Thermal Pad G 0.5 mm – (120 x 24 mm) EAN: 3830046996763

Thermal Pad F 1.0 mm – (120 x 16 mm) EAN: 3830046996732

STEP 2

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

For this step, you will need:

Thermal Pad - 120 x 16 x 1.0 mm

Thermal Pad - 120 x 16 x 1.5 mm

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!
