Frequently Asked Questions

Q: What PC case sizes are compatible with this silent case fan?

A: This OUYUANSU silent fan is available in 80mm, 90mm, and 120mm sizes, covering the most common standard mounting slots found in ATX, Micro-ATX, and Mini-ITX desktop PC cases. Always check your case's fan mount dimensions before ordering.

Q: How quiet is the OUYUANSU silent computer fan during operation?

A: The fan operates at just 25dBA — a whisper-quiet level that is barely noticeable even in a quiet room. Thanks to its fluid bearing technology and 7-blade design, airflow is smooth and turbulence is minimized for near-silent cooling.

Q: Is this fan compatible with my motherboard's 3-PIN header?

A: Yes. This fan uses a standard 3-PIN connector and runs at 12V DC, making it compatible with the vast majority of desktop motherboards that feature a 3-PIN fan header. Note that speed control via PWM requires a 4-PIN header — this fan supports voltage-based speed adjustment through a 3-PIN connection.

Q: Can this fan be used for both intake and exhaust airflow in a PC case?

A: Absolutely. The fan can be mounted for either intake (drawing cool air in) or exhaust (pushing warm air out) depending on the installation orientation. Refer to the arrow markings on the fan frame to identify airflow and rotation direction.
