Frequently Asked Questions

Q: Are the K4 ARGB fans compatible with my motherboard's RGB header?

A: The K4 fans use wireless ARGB linkage synchronization, meaning all three fans sync their lighting effects with each other wirelessly. Please confirm the ARGB connector type is compatible with your specific motherboard's 5V ARGB header before purchase.

Q: Can I use the K4 120mm fans on a water cooling radiator?

A: Yes! The K4 Triple Pack is fully compatible with both air cooling setups and water cooling (AIO or custom loop) radiators. Their 120mm size fits standard 120mm, 240mm (2x fans), and 360mm (3x fans) radiator configurations.

Q: How does the temperature-controlled speed feature work?

A: The K4 fans automatically adjust their RPM between 800 and 2000 based on detected system temperatures. At lower temperatures, the fans spin slower for quiet operation; as heat increases, fan speed ramps up to maintain optimal thermal performance.

Q: Do all three fans need to be connected individually?

A: Thanks to the wireless linkage technology, the fans synchronize their ARGB lighting without additional RGB cables between them, simplifying installation and reducing cable clutter inside your case.
