Product description
What it is and what it solves
The ELUTENG 2-in-1 dual-row 120mm USB fan is a compact cooling solution that plugs straight into a USB port. Designed to be positioned horizontally or vertically, it aims to improve cooling for a range of devices from PCs and laptops to routers, PS4 and media boxes. With two fans connected in tandem, the unit offers a straightforward way to boost airflow without wiring or dedicated power supplies.
How it works
Powered via USB, this fan features 3 adjustable speeds (low/medium/high) giving you 900, 1200 and 1500rpm options. The corresponding airflows are stated as 23.9, 27.9 and 31.98 CFM per fan, with noise levels ranging from about 25.6 dB to 32.5 dB depending on speed. A built‑in digital temperature controller provides a temperature readout and supports two modes: heating and cooling. You can set start and stop temperatures, apply a temperature correction, and choose a delayed start.
What stands out and where it may fall short
On the plus side, you get a compact 12 x 12 cm footprint with a 1 m cable and removable rubber shock absorbers on the bottom for vibration dampening. The design includes dual metal grids on either side for safety and wire protection at the corners, which helps reduce accidental finger contact and snag risks. The 2‑fan arrangement should offer more noticeable cooling than a single‑fan unit in the same form factor. On the downside, the description mixes practical features with a few specs that could be clearer in real‑world use (for example, the stated input/output figures seem atypical for a USB device). If you prioritise precise thermal control in a quiet setting, you may want to verify how the temperature controller performs with your specific equipment and consider potential trade‑offs in noise at higher speeds.
Who this is for
This is a pragmatic option for those who want an inexpensive way to improve airflow to devices that sit in close quarters or lack built‑in active cooling. It’s suitable for laptops, desktop peripherals, routers, TV boxes, PS4, or small AV gear where a USB‑powered fan is convenient and straightforward.
Who it isn’t ideal for
If you require near‑silent operation or push cooling to the limits of high‑end components, a larger or purpose‑built cooling solution may be more appropriate. Also, if your setup relies on more than 220V thermal control or advanced smart cooling features, this unit may feel limited.
When it makes sense to buy
Consider this ELUTENG fan when you want an easy plug‑and‑play cooling upgrade that doesn’t require extra wiring, especially for small to mid‑sized devices with USB ports. The dual‑fan setup can be helpful for devices that run warm and are close together, such as a PS4, router, or external hard drive enclosure.
What to check before buying
- Confirm the device you plan to cool has a USB port for power.
- Think about where you’ll place the fans (horizontal vs vertical) and whether the 1 m cable length is sufficient.
- Consider ambient noise tolerance at different speeds, especially if the unit will be near living or working spaces.
- If precise temperature control matters, review how the digital display and control features respond in practice with your hardware.
Practical use case
Imagine a compact NAS enclosure that sits under a TV box. With the ELUTENG fans plugged into a nearby USB port, you can set a modest cooling level for daytime use and switch to higher speed during heavy transfers or streaming crunch times. The non‑permanent rubber feet help minimise vibration on a desk or shelf, making it a low‑hassle addition.
Final verdict
Is it worth it? Worth considering if you want a straightforward, USB‑driven cooling add‑on without a lot of setup. It’s a sensible option for budget‑conscious users who need a bit more airflow for paired devices or small AV/PC gear and are comfortable managing trade‑offs around noise and exact temperature control.
FAQ
- How many devices can it cool effectively at once? The design links two 120mm fans to run together, which should boost airflow over a single unit in the same footprint, though real‑world results depend on your setup.
- Can I use it with a wall‑socket powered device? The unit is USB powered, it’s intended for USB ports rather than direct mains power.
- What maintenance does it require? Routine attention to the protective grids and ensuring cables aren’t strained will help longevity, the rubber feet can be left in place or replaced if worn.
