Frequently Asked Questions

Q: Is this 120mm ARGB fan compatible with all motherboards?

A: The OULLX 120mm fan uses a standard 5V 3-pin ARGB connector, which is compatible with most modern motherboards from brands like ASUS, MSI, Gigabyte, and ASRock that support 5V ARGB headers. The PWM speed control uses a standard 4-pin connector. Always verify your motherboard's header specifications before purchase.

Q: How loud is this fan during normal operation?

A: Thanks to its fluid bearing design and optimized 7-blade geometry, the OULLX 120mm fan operates at a very low noise level of just 20 dBA, making it virtually silent during everyday computing tasks. At lower PWM speeds, it runs even quieter.

Q: Can I use this fan for both case airflow and radiator cooling?

A: Yes! The OULLX 12CM fan is designed for use with computer cases and radiators alike. Its airflow rating of 48.5 CFM and variable speed range (600–1600 RPM) make it versatile enough for both intake/exhaust case configurations and 120mm liquid cooling radiator setups.

Q: How long will this fan last?

A: The fluid bearing is rated for an impressive 40,000 hours of continuous operation, giving you years of reliable, consistent performance in your PC build.
