Brand: EKWB
Product Type: CPU Water Block
Introduction and Disclaimer
Please note that the installation of this product is intended to be undertaken by an adequately trained and experienced person. 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 EKWB tech support for assistance. EKWB 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:
- Please carefully read the manual before beginning 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, EKWB recommends the use of EK-Cryo Fuel coolants.
- Make sure to thoroughly bleed air out of your water block, or you will not reach optimal performance.

Preparing the Motherboard
Follow these steps to prepare your motherboard for installation:
Step 1: Remove Motherboard
If already installed, please remove the motherboard from your computer and place it on an even surface.
Step 2: Remove Hold-Down Clamps
Using a Philips-head screwdriver, remove the four UNC 6-32 screws securing the original plastic hold-down clamps around the CPU socket, as shown in the illustration. Remove the hold-down clamps and store them away.
Diagram shows a motherboard with arrows indicating removal of hold-down clamps using a screwdriver.
Step 3: Clean the CPU
Wipe the CPU's Integrated Heat Spreader (IHS) clean using a non-abrasive cloth or Q-tip, as shown in the illustration.
Diagram shows cleaning the CPU IHS with a cloth.
Step 4: Apply Thermal Compound
Apply the enclosed thermal grease (thermal compound) on the CPU heat spreader (IHS) as shown in the image. The layer of the thermal compound must be thin and even in thickness 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 [tube icon]
Diagram shows applying thermal grease to the CPU IHS.
Installing the Water Block
Follow these steps to install the water block:
Step 1: Remove Protective Foil
Before placing the water block, it is mandatory to remove the protective foil from the backside of the water block.
Diagram shows the water block with a protective sticker being peeled off the back.
Step 2: Position Water Block
Position the CPU Water Block onto the motherboard. Make sure to align the holes as shown in the picture.
Before placing the water block, it is mandatory to remove the protective foil from the backside.
Make sure to double-check the layer of the Thermal Grease before placing the water block onto the motherboard.
Diagram shows the water block being placed onto the motherboard, aligning with mounting holes.
Step 3: Secure Water Block
Secure the water block from the backside of the motherboard using the included Tx7 L-Shaped wrench. Tighten the mounting screws in an anti-clockwise direction. Start fastening the screws in a cross pattern. Do not tighten fully until all of the screws are partially screwed in.
The Tx7 L-Shaped wrench must be used in a standing position! Otherwise, the mounting screws may crack during tightening!
For this step, you will need: Tx7 L-Shaped wrench [wrench icon]
Diagram shows securing the water block from the back of the motherboard using the wrench and screws.
Step 4: Connect Fittings
With EK-Velocity² series water blocks, it is mandatory to use the bottom port as the INLET.
Mixing the ports may result in poor thermal performance of the water block.
Tighten the fittings in a clockwise direction until the gasket underneath is compressed. The installation of the Velocity² water block is now complete.
Diagram shows the water block with inlet and outlet ports labeled, and fittings being tightened.
Connecting the D-RGB LED Strip
Follow these steps to connect the D-RGB LED strip:
Step 1: Connect to Motherboard Header
Plug the 3-pin connector from the water block's D-RGB LED light to the DRGB HEADER on the motherboard. The LED will work if the pin layout on the header is as follows: +5V, Digital, empty, Ground.
Please ensure that the arrow indicated on the connector is plugged into the +5V line as indicated on your motherboard. If you put the LED Diode to the 12V RGB HEADER, you can damage the LEDs. Failure to do so will damage your motherboard or LED strip.
Diagram shows the D-RGB connector being plugged into the motherboard's DRGB HEADER.
Testing the Loop
To ensure the installation of EK components was successful, 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 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. In the eventuality of 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.
Warranty
EKWB products are warranted against defects of materials and quality for a period of 24 months, starting from the date of delivery to the end-user. During this period, products will be repaired or have parts replaced at EKWB's discretion, provided that:
- The product is returned to the agent from whom it was purchased.
- The product has been purchased by the end-user and has not been used for commercial purposes.
- The product has not been misused, handled carelessly, or used in a manner other than described in the instructions manual.
This warranty does not confer rights other than those expressly set out above and does not cover any claims for consequential loss or damage. This warranty is offered as an extra benefit and does not affect your statutory rights as a consumer.
This warranty is voided if the product comes into contact with aggressive UV additives or other improper liquids. EK water blocks are sealed with a warranty-voiding circular label, proving the water block has withstood a pressure leak test. Removing the label will void the leak-free guarantee, but not the guarantee on the product itself.
Any other RMA issues can be reported to EK Customer Support at www.ekwb.com/support for further analysis.
