Compact 40 mm USB cooling fan

The TSUJ 4015 is a 40 mm square frame fan that runs on 5 V DC at 0.28 A and connects through a standard USB plug. It suits hobbyists and technicians who need targeted airflow for small enclosures, router boards, or single-board computer projects.

Tool-free USB installation

Plug the fan into any powered USB port and it spins immediately; no drivers or soldering are required. The 15 mm thickness limits use in ultra-slim chassis, and the fixed USB cable length may restrict placement in larger cases.

Questions about this item

How can I confirm the TSUJ 4015 DC5V 0.28A 40x40x15mm Ball USB Fan is spinning correctly after plugging it in?

The fan should spin smoothly and quietly when connected to a 5 V USB port; listen for the ball-bearing rotation and feel airflow from the 40 mm frame.

What comes with the TSUJ 4015 DC5V 0.28A 40x40x15mm Ball USB Fan and what must I provide separately?

The package includes the 40x40x15 mm ball-bearing USB fan only; you must supply a 5 V USB power source such as a port, adapter or power bank.
