Manufacturer description
The ELUTENG 40mm USB fan is a single-purpose cooling solution for the cramped spots a case fan cannot reach. It runs off any 5V USB port, so you can power it from a TV box, a powered hub, a console's front port, or a wall adapter without opening anything up. The three-speed inline switch steps voltage between 3.5V, 4.2V, and 5V, moving 3.5, 3.88, or 4.4 CFM at up to 5300RPM, which lets you trade airflow for quiet depending on whether the fan is parked next to a router or aimed into a small PC case. ELUTENG fits a metal grill over the front to protect the blades, your fingers, and the 100cm…
SpecPicks Verdict
SpecPicks scored ELUTENG 40mm USB Fan using a rating × review-volume × price-fit model applied to published specs and reviews across the retro cpu coolers & fans category. ELUTENG's retro cpu coolers & fans lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Frequently Asked Questions
Will this fan cool my PlayStation or Xbox?
It is listed as compatible with PlayStation, Xbox, DVRs, and receivers. Plug it into a USB port on the console or a nearby hub and aim it at the vents. At 4.4 CFM it supplements existing airflow in a tight cabinet rather than replacing internal cooling.
How loud is it?
ELUTENG does not publish a decibel rating, so check the listing for current noise specs. The three-speed switch drops voltage to 3.5V and airflow to 3.5 CFM on the low setting, which is the quietest mode if noise matters more than cooling.
Can I plug it into a phone charger or wall adapter?
Yes, any 5V USB source works. ELUTENG specifies a maximum input of 5V/1A and warns that exceeding it may damage the motor, so avoid high-voltage fast-charge adapters and stick to a standard 5V port.
How long is the cable?
The USB cable is 100cm, or 3.3 feet. That is enough to reach from a rear console port or a wall adapter to a shelf or cabinet position, but you will need an extension for longer runs.
Does it come with mounting hardware?
The listing covers the 40mm fan, metal grill, and 100cm USB cable, with no screws or bracket described. ELUTENG asks buyers to confirm the size against the product photos before ordering, so verify the 40mm footprint fits your gap first.
