In this guide, I'm going to run you through the process or taking off your old NVIDIA GTX 1080 Ti GPU cooling shroud and components, and how to fit a new water block to the card for it to be included in a custom water cooling PC loop.

How to install the GTX 1080 Ti water block

Firstly, you'll need to buy a water block that supports your GTX 1080 Ti. Not all of them are made the same so shop around and make sure it'll be compatible with your PCB. For instance, this XSPC GTX 1080 Ti water block we use here works with NVIDIA Founders Edition cards only. Usually, these kits include all the screws and tools you need.

  1. Remove the factory-fitted cooling system. This differs per manufacturer and cooler design, but usually involves the removal of numerous screws, including the backplate.

  2. Using a dry cloth or paper towels, gently rub a small amount of isopropyl alcohol to the GPU surface to remove the old heatsink paste.

  3. Once the card is clean and dry, apply a small amount of heatsink paste.
  4. Peel away all the protective labels on the GPU block.
  5. Gently sit the water block on the top of the GPU, lining it up and press down slightly to spread the heatsink paste.
  6. Flip the GPU over and rest it on the block.
  7. Lay down the backplate onto the rear of the GPU.
  8. Screw all three parts together.

All that's left to do is flush out the block, which you can do prior to connecting the GPU to the water loop in the PC or do it in one go with the loop. Just be sure to use a good kit to make sure the PH balance is about right. I've included a link to purchase the Mayhems Blitz kit which has always served me well.

XSPC GTX 1080 Ti Water Block

Perfect for Founders Edition cards

This water block from XSPC has everything you need to keep your reference GTX 1080 Ti from NVIDIA cool under load.

Not only will you be able to overclock this card after installing a water block like this XSPC solution, the company even took the time to include RGB lighting as well as tempered glass and a copper base. You'll be creating a light show, which has been scientifically proven to add an extra 50 frames to your gaming performance.

Additional Equipment

As well as the GPU water block, you'll need some alcohol and thermal paste.

Isopropyl Alcohol ($12 at Amazon)

You can't take off an older cooler, leave the thermal paste behind and reuse it with a new cooler. You need to remove it, which is where alcohol comes in.

Thermal Paste ($8 at Amazon)

This is some seriously good stuff. The thermal compound from ARCTIC allows the transfer of heat from a component like the GPU to an active cooler.

Mayhems Blitz Kit ($23 at Amazon)

The Mayhems Blitz Kit is the ideal package full of everything you need to clean out a water cooling loop to get it prepared for new fluids.
