Common questions about manuals, registration, and support for this brand.
Yes, it is highly recommended to use corrosion-inhibiting coolants for all liquid cooling systems. It is mandatory for nickel-plated water blocks to prevent damage. EK recommends their EK-CryoFuel coolants.
No, EKWB does not recommend using pure distilled water as it lacks the necessary corrosion inhibitors and biological growth preventatives. For best results, use a purpose-made coolant like EK-CryoFuel.
To test your loop, connect the pump to a power supply outside your system (or use a jumper bridge on your PSU) while leaving other components unpowered. Run the pump continuously for 24 hours to ensure there are no leaks before powering on the rest of the PC.
For many modern EK water blocks (such as the Quantum line), adhering to the specific inlet and outlet ports is mandatory. Reversing the flow can result in significantly poor thermal performance. Always check the manual for the correct flow direction.
To bleed air, run the pump at 100% speed and tilt the chassis in various directions to help trapped air bubbles move to the reservoir. Ensure the reservoir lid is open or has a way for air to escape if the loop allows, but be careful not to spill coolant.
