EK-PRO GPU WB RTX A6000 - Ni + Inox

Basic Guidelines

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 a flat surface and carefully remove the stock cooler. Do not forget to unplug all the LED and fan connectors.

Step 2: Cleaning the PCB

Wipe off the remains of the original thermal compound using a non-abrasive cloth or Q-tip. Denatured alcohol is recommended for removing TIM leftovers. After that, remove all remaining stock thermal pads from the PCB.

Cutting and Placing Thermal Pads

The GPU water block comes with pre-cut thermal pads to cover VRM components, such as COILs, MOSFETs, and drivers. Use 1.0mm thick thermal pads as illustrated. EK provides an adequate quantity of thermal pads. You must remove the protective foil from both sides of the thermal pad before installation.

Applying Thermal Compound

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!

For this step, you will need: Thermal Grease.

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 pre-installed standoffs on the graphics card. Align 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.

Diagrams demonstrating the process of placing the water block onto the graphics card.

Step 2: Attaching the Backplate

To attach the graphics card to the water block, use the stock cross backplate. Mount it with polyamid M2.5 pads and stock M2.5x4 screws.

Diagrams showing the backplate being attached with screws and washers.

Securing Power Cable

Step 3a: Connecting the Power Adapter

Insert the 8-pin power connector into the inox adapter. Ensure the pads on the power adapter are aligned with the openings in the inox power adapter. Pay attention to the orientation of the latch on the connector.

Diagram of the 8-pin power connector being inserted into the adapter.

Step 3b: Mounting the Power Adapter

Fasten the inox power adapter to the water block with two (2) M3x6 screws. Minor bending and twisting of power cables may be needed to attach the power adapter to the water block.

Diagram showing the power adapter being screwed onto the water block.

For this step, you will need:

• Screw M3 x 6 DIN 7991 (2x) [Part No. 9029]
• Allen Key 2 mm (1x) [Part No. 8901]

Installing Thermal Pads and Applying Thermal Compound

Step 4: Placing Thermal Pads

Install 1.0 mm thick thermal pads on the PCB, as illustrated, to ensure a better connection between the graphics card and backplate. EK provides an adequate quantity of thermal pads.

Diagram illustrating the placement of 1.0mm thermal pads (G1 Thermal Pad - 120 x 24 mm) on the PCB.

Step 5: Applying Thermal Grease

Apply the enclosed EK-TIM Ectotherm thermal grease (thermal compound) on the water block spreader, as shown in the image. The layer of the thermal compound must be thin and even over the entire marked surface.

Diagram showing the application of thermal grease on the water block spreader.

Step 6: Attaching the Backplate

Use ten (10) M2.5 x 8 AX1 screws. Tighten the screws evenly using a 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. 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.

Testing the Loop

To ensure the installation of EK components was successful, 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. In case of coolant leaks, fix the issue and repeat the testing process. To prevent possible damage, ensure all hardware is dry before the system is powered on.
