ELUTENG USB Fan 40mm

I was experimenting with tiny laptop fans as the premium priced air source heat pump (lower temp) radiator brands use similar to accelerate their heating emittance power - but they are fiddly to add to an existing radiator. Then I spotted this larger 5V fan and have installed it easily, running quietly at low rpm, probably under 1W usage... and it works well to boost the heat in a cold kitchen. A very simple, cheap and easy to fit solution for radiators that are slightly underpowered.

I am using this to help cool a Linear Power Supply. Rather than the fan extract the heat more rapidly I removed the grill and turned it upside down to blow cool air into the power supply. Even on the low setting it has performed exactly as I needed it to. I didn’t want to freeze the LPS just bring the heat down a few degrees. The 40mm size is perfect for the Sengterbelle 12v LPS leaving enough venting either side of the fan for the air to escape. I would like to know how long I can leave this fan on for but there is no info on a constant run so it looks like trial and error but in the meantime the heat is under control even without going high on the setting, works just fine on low. Some say this fan is noisy but seriously I am not sure what they maybe using it for but I have had louder mosquitoes in my ears than this fan! It’s quiet.

Sounds a little like a PS2 starting up at high but does the job Doesn't push the most air but does the job, good to keep my laptop cooler and less noisy when gaming or using ai. Seems like it could be good for circulating air in a TV unit with modern consoles or PC also

Good little fan,3 speed and quiet

Very good little usb fan has 3 speed settings. It is a little bit louder than I expected as was expecting a silent fan but very fit for purpose. There is little in the way of instructions and couldn't figure out how the included screws were supposed to be used with the covered holes underneath the metal fan cover /guard but made a plan with the current screws and the guard on my applied surface which was thin enough to work with

This USB fan has been a lifesaver for my old PC — it helped prevent it from overheating and keeps it running smoothly. After I started using it, my stepbrother even took it over because it works so well, and it’s still going strong! One thing I really like is that it doesn’t wiggle around or vibrate too much, so it feels sturdy and stable even when running. Installation was super easy — I just plugged it in, and it was good to go with no hassle. It’s also got a sleek, clean design that fits nicely with my setup without looking bulky or out of place. Overall, this USB fan is reliable, effective, and looks good doing its job. Definitely recommend if you need a simple cooling solution!

I deployed a fanless mini PC firewall appliance, but found that it was running hotter than I liked. I stuck some rubber feet on this fan and set it on top (120mm is ideal size), and run it on low speed off the USB port. It's practically silent, and very effective at low speed. Two years later, running 24x7, it's still working, and still quiet.

A bit noisy but good airflow

Ventilatortje met regelbare standen in het snoer met sub stekker. Het werkt wel, maar maakt toch waat meer geluid dan gedacht en gehoop, en heeft ook een hoogfrequent bijgeluid.

Was working perfectly it is for the minisforum for keep away overheating issue

Gillar hastighets regleringen, fungerar bra till det den var ämnad för.

Ich nutze den 120-mm-RGB-Lüfter zur zusätzlichen Kühlung meines externen SSD-Gehäuses und bin positiv überrascht, wie gut die Leistung für den günstigen Preis ist. Lautstärke & Betrieb: Auf Stufe 1 ist der Lüfter kaum hörbar, eignet sich also perfekt für den Dauerbetrieb am Schreibtisch. Trotz der geringen Lautstärke erzeugt er bereits einen spürbaren Luftstrom. Auf höheren Stufen nimmt die Leistung deutlich zu, bleibt aber immer noch angenehm leise. Kühlleistung: Die Kühlung ist sehr effizient: Meine WD Black SN850X erreicht im Gehäuse nur 13 °C im Idle und etwa 34 °C unter Last – für eine so schnelle SSD ein hervorragender Wert. Damit bleibt das Gehäuse selbst bei längerer Nutzung angenehm kühl. Optik & Verarbeitung: Die RGB-Beleuchtung sieht hochwertig aus, gleichmäßig ausgeleuchtet und nicht übertrieben hell. Der Lüfter wirkt gut verarbeitet und läuft rund ohne Vibrationen. Fazit: Für den Preis bietet dieser Lüfter überraschend starke Leistung, ist sehr leise und optisch ansprechend. Ideal für SSD-Gehäuse, Router, Mini-PCs oder andere kleine Geräte, die zusätzliche Luft benötigen. Klare 5 Sterne.

Ottimo usato per quadri elettrici dove ci sono ups e nvr dvr modem
