USER GUIDE
Important Safety Information and Guidelines
Installation of this product is intended for adequately trained and experienced persons. You are installing the product at your own risk. If you are not properly trained or experienced, or feel unsure about the installation procedure, please refrain from installing the product yourself and contact EK Water Blocks tech support for assistance. EK Water Blocks disclaims liability for any damages to the product, as well as incidental, consequential, or indirect damages incurred due to improper or inappropriate installation.
Before you start using this product, please follow these basic guidelines:
- Carefully read the manual before beginning with the installation process.
- The EK Fittings require only a small amount of force to screw them firmly in place, as the liquid seal is ensured by the rubber O-ring gaskets.
- The use of corrosion inhibiting coolants is always recommended for liquid cooling systems, and mandatory for nickel-plated water blocks.
- Do not use pure distilled water. For best results, EK recommends the use of EK-CryoFuel coolants.
- Make sure to thoroughly bleed air out of your water block, or you will not reach optimal performance.

Installing the Water Block
Follow these steps for installation:
- Step 1: Preparation
If the motherboard is already installed, remove it from your computer and place it on an even surface. - Step 2: Cleaning the CPU
Wipe the CPU's Integrated Heat Spreader (IHS) clean using a non-abrasive cloth or Q-tip. Ensure the surface is clean. - Step 3: Applying Thermal Compound
Once clean, apply a line of Thermal Compound on one edge of the IHS. Use a credit card or similar flat object to spread it evenly across the entire surface. The layer of Thermal Compound must be thin and even. Excessive or irregular application may lead to poor performance. - Step 4: Mounting the Water Block
Align the water block properly on the motherboard. Note that the mounting screws are not positioned in a square pattern. Before proceeding, it is mandatory to remove the protective foil from the backside of the water block. Start fastening two mounting screws at a time, preferably in a cross pattern. Do not tighten them fully until all screws are partially screwed in. Then, using the 2.5 mm Allen Key, screw in all four mounting screws until you reach the end of the thread. Ensure a maximum torque of 0.6 Nm.
Fittings and Tubing
Step 1: Connecting Fittings and Tubing
EK recommends the use of EK-HFB 10 mm barb fittings and EK-Tube ZMT 10/16 mm Matte Black tubing.
The INLET port is located on the right side of the water block.
The installation of the CPU water block is now complete.
Testing the Loop
To ensure the installation of EK components was successful, EK recommends performing a 24-hour leak test.
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 other components. Turn on the PSU and let the pump run continuously.
Inspect all parts of the loop. 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 to prevent any damage.
