Compact 5 V cooling fan

The TSUJ DF310RI05S1C-02 is a 30 mm by 10 mm axial fan designed for low-voltage thermal management. It operates from a 5 V supply and draws 0.1 A through a three-wire lead. The compact frame suits tight enclosures where space is at a premium.

Capacity and headroom

At 5 V and 0.1 A the unit delivers modest airflow suited to light heat loads such as router boards, small power supplies or single-board computers. It cannot handle sustained high-wattage components or multi-core processors that demand larger heatsink airflow.

Three-wire connection benefit

The three-wire interface provides a tachometer signal so the host can monitor rotor speed in real time. This allows automatic shutdown or alerting if the fan stalls, a safeguard absent from two-wire models. No additional software or controller is bundled.

Questions about this item

Will the 5 V 0.1 A three-wire fan connect to an older motherboard header that only supplies 5 V?

Yes, the fan is rated for 5 V and 0.1 A, so a legacy 5 V header can power it directly.

How can I confirm the fan is running correctly once installed?

Check that the blades spin smoothly and listen for steady airflow; the three-wire connection also lets the board report RPM if the header supports monitoring.

Does the package include mounting screws or a connector adapter, or must I buy them separately?

The box contains only the 30 × 10 mm fan with its attached three-wire lead; screws and any adapter are not included.
