Preparing the Water Block for Installation

Step 1: Unscrew Backplate and Standoffs

Unscrew six (6) Screws AX1 M2.5 x 8 mm. Remove the backplate together with Screws and backplate standoffs. Standoffs must stay on Screws AX1 M2.5 x 8 mm. Remove the PCB cardboard. Save the removed parts for later steps.

DO NOT REMOVE STANDOFFS FROM SCREWS!

In case the standoff detaches from the screw, replace it with a spare one. When replacing the standoff, make sure that you screw it on the AX1 M2.5 x 8 screws. Do not push the standoff onto the screw AX1 M2.5 x 8 mm.

For this step, you will need:

• Phillips Head Screwdriver ?

Cutting and Placing Thermal Pads

Thermal Pad Types

• Thermal Pad F - 1.0 mm (120 x 16 mm)
• Thermal Pad F - 2.0 mm (120 x 16 mm)
• Thermal Pad G - 1.0 mm (120 x 24 mm)

Step 1: Prepare Thermal Pads

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.

CAUTION: You must remove the protective foil from both sides of the thermal pad before installation.

Replacement thermal pads:

• Thermal Pad F 1.0 mm – (120 x 16 mm) EAN: 3830046996732
• Thermal Pad F 2.0 mm – (120 x 16 mm) EAN: 3830046996756
• Thermal Pad G 1.0 mm – (120 x 24 mm) EAN: 3830046996770

Step 2: Place Thermal Pads on PCB

Once cut to the size, Thermal Pads should be placed on the PCB, as shown in the diagram. (Pad labels: F1, F2, G1)

Applying Thermal Compound

Step 1: Apply Thermal Grease

Apply the enclosed 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 ?

Attaching the Water Block

Step 1: Position Water Block

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 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!

Step 2: Tighten Screws

Use five (5) M2.5 x 4 AX1 Screws and PVC washers to tighten the PCB on the water block. 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.

Screws must be present in the places marked on the picture.

For this step, you will need:

• M2.5 x 4 AX1 Screw (5 pcs)
• Polyamide Washer (5 pcs)
• Phillips Head Screwdriver ?

Installing the Backplate

Step 1: Prepare Thermal Pads for Backplate

After attaching the water block, a few more thermal pads need to be cut into smaller pieces to cover all the necessary components. EK made sure to provide you with more than an adequate quantity of thermal pads to complete this step.

CAUTION: You must remove the protective foil from both sides of the thermal pad before installation.

Replacement thermal pads:

• Thermal Pad F 1.0 mm – (120 x 16 mm) EAN: 3830046996732
• Thermal Pad F 2.0 mm – (120 x 16 mm) EAN: 3830046996756
• Thermal Pad G 1.0 mm – (120 x 24 mm) EAN: 3830046996770

Step 2: Apply Thermal Pads to Backplate

Apply the thermal pads onto the backplate as shown in the diagram. (Pad labels: F1, F2, G1)

Attaching the Backplate

Step 1: Position Backplate and I/O Bracket

Position the I/O Bracket and backplate (including screws and standoffs) onto the GPU PCB. Make sure all the holes are aligned. Tighten the screws evenly.

Before attaching the backplate, make sure all the Thermal Pads are placed correctly!

Do not use excessive force!

For this step, you will need:

• Phillips Head Screwdriver ?

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.

Fittings and Tubing

Screw in two (2) G1/4 threaded male fittings. Attach the liquid cooling tubes and connect the water block to the cooling loop.

Do not forget to plug the remaining two openings using the enclosed EK-Plug G1/4 or its equivalent.

EK recommends using EK fittings with all EK water blocks.

CAUTION: When using connectors other than EK fittings, pay special attention to the length of the fittings' male G1/4" thread – 5mm is the maximum G1/4" thread length allowed!

For this step, you will need:

• EK-Loop Multi Allen Key ?

Connecting the D-RGB LED Strip

Step 1: Connect to Motherboard

Plug the 3-pin connector of the distribution plate D-RGB LED light to the D-RGB HEADER on the motherboard. The LED will work if the pin layout on the header is as follows: +5V, Digital, Empty, Ground.

Incorrect installation or installation to a wrong header can damage the LED strip or the header itself!

Testing the Loop

To make sure the installation of EK components was successful, we recommend you perform a leak test for 24 hours. When your loop is complete and filled with coolant, connect the pump to a PSU outside of your system. Do not connect power to any of the other components. Turn on the PSU and let the pump run continuously. It is normal for the coolant level to drop during this process as air collects in the distribution plate. Inspect all parts of the loop, and in the eventuality, that coolant leaks, fix the issue and repeat the testing process. Ensure that all hardware is dry before the system is powered on in order to prevent any damage.
