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 to install the EK-Pro GPU WB RTX 4090 WindForce V2 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.

CUTTING AND PLACING THERMAL PADS

STEP 1
Your GPU water block comes with uncut thermal pads to cover all the VRM components, such as coils, MOSFETs, and drivers. Please use 1.0 mm thick thermal pads which should be placed on the PCB, as illustrated below. EK made sure to provide you with more than an adequate quantity of thermal pads to complete this Step.

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

APPLYING THERMAL COMPOUND

Apply the enclosed EK-Loop Thermal Paste NGP (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.

warning: The excessive or uneven application of thermal grease may lead to poor performance!

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 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.

warning: Pay attention not to use too much force when pressing the block down to the PCB since chip dies are prone to cracking.

STEP 2
Use seven (7) 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.

For this step, you will need :

INSTALLING THE BACKPLATE

STEP 1
Install 1.5 mm and 2.0 mm thick thermal pads on the Backplate as illustrated, to ensure a better connection between the graphic card and the backplate. EK made sure to provide you with more than an adequate quantity of thermal pads to complete this Step.

STEP 2
ATTACHING THE BACKPLATE
Use eight (8) M2.5 x 7 AX1 screws. Tighten the screws evenly using the Phillips head screwdriver.
The screws must be present in the places marked on the picture.

For this step, you will need:

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 the Steps from the previous section to re-attach the block.

warning: 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.

warning: 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, 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.

FAQ

• Q: Can I use pure distilled water as a cooling liquid?
  • A: No, it is not recommended to use pure distilled water as a cooling liquid. EK recommends the use of EK-CryoFuel Coolants for best results.
