Compact 40 mm USB Fan

The SunnyStar TSU-4010-05 is a 40 mm square frame fan designed for 5 V USB power. It draws 0.08 A through a two-wire connection and suits small enclosures or peripheral cooling where space is limited.

Steady Low-Power Airflow

At the rated 5 V the motor runs continuously within its 0.08 A envelope, so output remains stable during extended operation. There is no speed-control wire, so the fan maintains a fixed rate as long as the USB port supplies power.

USB 5 V Interface Limits

The two-wire lead expects a standard 5 V USB supply capable of at least 0.08 A. Ports that negotiate higher voltages or current-limited hubs below that threshold will not drive the fan reliably.

Questions about this item

How loud is the TSU-4010-05 when it runs continuously on 5 V?

The 40 mm fan draws only 0.08 A at 5 V, so airflow and noise remain minimal during all-day operation.

What connector or power source does the 2-wire 5 V fan need?

It uses a bare 2-wire lead that plugs directly into any 5 V USB header or port.

Will the 40*40*10 mm frame fit the same mounting holes as my old 40 mm cooler?

Yes, the 40 mm square footprint matches standard 40 mm fan mounting patterns.
