How to Install the NZXT Kraken G12 GPU Mounting Kit

The NZXT Kraken G12 allows you to quickly mount any Kraken Series liquid cooler onto a graphics card.

It delivers a 40% increase in cooling capacity over stock cooling, and features a newly designed bracket with an easier installation process versus the Kraken G10.

Plus, the Kraken G12 is also compatible with more than 30 liquid coolers on the market.


Step 1: Prepare the Graphics Card

Remove the original cooling module from your graphics card.

Step 2: Prepare the GPU Bracket

Install the fan with the label facing the GPU bracket using the fan screws.

Attach the two foam pieces at the corners while making sure the foams will not interfere with components on the graphics card.

Step 3: Identify the Mounting Holes and Retention Brackets

Identify the correct mounting holes on the GPU bracket and prepare the required retention brackets for your graphics cards.

Step 4: Prepare the Retention Brackets

Mount the retention brackets using screws and washers to prevent risk of damage to your graphics card.

Step 5: Prepare the Pump

Referring to your liquid cooler’s instructions, remove the Intel or AMD retention bracket if it is already installed.

Step 6: Install the Pump onto the GPU Bracket

Orient the pump’s tubes along the side with cable tie points.

Pass the pump through the GPU bracket’s grooves.

Rotate the pump until it aligns with the GPU brackets and attach.

Step 7: Install the GPU Bracket

Using the thumb screws with spring, install the GPU bracket onto the graphics card.

Step 8: Manage the Tubes and Cables

Use the included cable ties to manage the tubes and cables along the trench with tie points.

Step 9: Connect the Fan

Connect the 3-pin fan connector to the liquid cooler’s fan power or to an open fan headers on the motherboard.

Step 10: Install the Assembled Graphics Card

Follow the liquid coolers instructions and complete all necessary connections to complete the installation of your graphics card. This can include pump power, USB, and software installation.
