Frequently Asked Questions

Q: What fan sizes are compatible with this M4 chassis heat sink fan mount?

A: This mount uses standard M4 screw and nut hardware, making it compatible with most common fan sizes (such as 80mm, 92mm, and 120mm fans) that use M4 mounting holes. Always verify your fan's mounting hole pattern before purchase.

Q: Is the magnetic suction strong enough to hold the fan securely during operation?

A: Yes — the kit uses a dual-retention system combining magnetic suction with M4 screws and nuts. This combination ensures the fan stays firmly in place even during continuous operation and under typical chassis vibration.

Q: Can this fan mount be used in both horizontal and vertical orientations?

A: This mount is specifically designed for vertical installation to optimize natural convection airflow in chassis and cabinet enclosures. While it can be adapted for other orientations, vertical mounting is recommended for best heat dissipation performance.
