Pros & Cons
Pros
- ✓ Dual 40mm fans cool from two angles at once, unlike single-fan USB coolers
- ✓ 5V USB power works off a console port or wall adapter, no PSU header needed
- ✓ Three-gear inline controller (L/M/H) tunes noise against airflow
- ✓ Hydraulic bearing rated for about 2x the life of standard fans
- ✓ Metal frame with finger guards for open-desk and shelf placement

- ✗ No PWM or thermal control; speed changes are manual only
- ✗ No stated mounting hardware, so placement depends on gravity and surface
Manufacturer description
The ELUTENG Dual 40mm USB Fan tackles the cooling problem most gear has no answer for: a router, TV box, or game console with no fan mount and no spare power header. Two 40x40x25mm fans sit in a shared metal frame and run off a single USB plug, so you can power them from a wall adapter or straight from the USB port on the back of a console. The three-speed inline controller steps between low, medium, and high, topping out at 5500RPM when you need maximum airflow over a hot external hard drive enclosure or a stack of AV equipment. Hydraulic bearing motors give ELUTENG's rated service life of…

Frequently Asked Questions
How loud is the ELUTENG dual 40mm USB fan?
ELUTENG states directly that the 40mm size requires higher RPM to move air, so some noise is generated. Use the low (L) gear for quieter running and reserve high (H) for peak heat.
Can I plug this into my PlayStation or Xbox directly?
Yes. The USB plug draws 5V and ELUTENG lists game consoles specifically, including powering from a USB port on the back of the console. A USB wall adapter also works.
What is the maximum fan speed?
Up to 5500RPM on the high setting. The inline controller also offers medium and low gears if you want to cut noise when the device is idling.
What size are the fans?
Each fan measures 40 x 40 x 25mm, excluding the metal frame. That footprint lets the pair fit narrow gaps around routers, TV boxes, and desktop tower vents.
Is this worth it for cooling an external hard drive enclosure?
ELUTENG calls out external hard disk boxes as a target use case, and the dual-fan layout covers more surface than a single unit.
Key Features

With a design of mini and lightweight, this usb fan can be used in narrow places such as computer hosts, routers, etc. It can also be placed in a small gap on a desk or computer to cool down electronic products. Note: the 40mm fan is small and the speed will increase to achieve the heat dissipation effect, so some noise will be generated during use.
- 【2 in 1 USB Fan】Compared to a single fan, the latest upgraded 2 in 1 dual usb fans can cool electronic products from different angles at the same time, which is more efficient. With a large air volume design and an external hard disk box, it can also cool electronic devices such as smart phones, game consoles and personal computers in a few seconds.

- 【Wide Application】This usb pc fan is not only suitable for cooling equipment such as personal computers, routers and HDDs, but also suitable for AV equipment and game consoles. Simply connect to a device equipped with a USB terminal than can start cooling easily without cumbersome wiring.
- 【Three Speeds】The computer fan has a multi-speed controller that sets the fan speed to the level of three different gears. 3 gears, low (L), medium (M) and high (H), can be adjusted by the user according to their needs.
- 【Easy to use】The USB plug of the small usb fan can be powered by a USB adapter or a USB port on the back of the game console, as well as popular audio electronic devices, which is very convenient to use.
