ELUTENG USB Fan 80mm 2 In 1 Computer Fan 5V Mini Desk Fan 2700RPM 32CFM Dual USB PC Fans Cooling Radiator with Black Metal Grill Double Fans For Home Office Bedroom Library

Great little fan. In fact I'd say I'm a massive fan of these fans. Have worked continuously for over a year and aren't too loud.

great product. bought the 80mm fans and they fit perfectly on a household double radiator. ive used them to boost the heat output for my radiator by providing forced air convection. they sit on top and really help to warm up the room quicker. three speed controller is useful. almost silent so youd never know they were there. to buy dedicated radiator fans would have cost over £50 so very good value for money, if a little heath robinson. just needed a USB power supply, but ive got loads of old usb phone chargers.

On full setting, these are loud! However that said, it does make a difference on my Xbox One X. I placed both on only one side of the intakes and can feel a difference in temperature on the external casing (cant confirm If this is actually true of the components but with the logic that the outside is much cooler then the inside must? Over all decent. Has 3 settings of Low, Medium and High. But as said, if set at high, it is quite loud.

On the lowest of 3 speed settings, there is a barely perceptible whirring sound - but you really have to be listening for it and it does not ever get obtrusive. Bought to cool down my CCTV DVR player which kept on cutting out due to overheat. A new hard drive and these fans have done the trick - the DVR box (running 24/7) is now cool to the touch and working fine.

Had that working for over a year now and they've been faultless. I have a dog cage in the back of my estate car and wanted some means of circulating the air around more in the cage. I have these stick to the top of the cage with double sided tape blowing through the gaps. I either plug them into a usb plug into the cars cigarette socket in the back of the car, or into a battery pack with rechargeable batteries I have secured to the cage. They do a great job of moving the air around the cage when my dog is in there helping to circulate the cooler air from the cars air conditioning. There are 3 speeds to the fans via the switch. Leaving them plugged in and the switch in the on position means that the fans start automatically whenever the car is running. If I need them to work when the engine is off I unplug the usb and plug it into the battery pack - it then runs independently until the batteries have died.

Decent little fans

Having bought the 'one piece' version to place under my hifi amp, I bought these in error as I thought they were the same. However, they were bought to cool my laptop, and as they are not conneted I was able to place them under the laptop's vents which are not side by side. They do the job, although anything above the first setting will be heard. Having said that, the first setting keeps the laptop cool all day.

They are fans, they spin in a fan like manner

Buscas un accesorio concreto. Analizas las caracteriscas de las ofertas y elijes el mas afín. Este conjunto es lo que buscaba, cumple con mis necesidades y con las características anunciadas. Montados sobre el radiador perfil Al de aletas, mantiene mi Nini PC , con ventilación estática por debajo de los 40°C estables, en pleno verano. El caudal regulable es suficiente para mantener estable la temperatura del mini PC. El nivel acústico es muy bajo. 50 (dB A) medidos al lado mismo, en interior con ventanas y puertas abiertas y sin sonido. Con el sonido activado no se aprecia la rumorusidad de los ventiladores. Con la normativa estándar se toman las improntas a un metro de la fuente ponderada. No esperen un tifón, el caudal, y presión son muy leves sensorialmente. Es importante analizar y valorar las necesidades y los resultados con los medios adecuados, para no caer en erróneas conclusiones descalificantes. Buena manufactura con calidad, diseño, presentación, rendimiento y con un precio adecuado.

Fungerade som förväntat. Låter en del om man inte kör på lägsta hastigheten men det gör de flesta när det är mindre fläktar.

Ça fait le taff ! Je les utilise pour refroidir une carte reseau et ça marche donc 5 étoiles J'en ai d'autres plus grands pour replacer des ventilateurs de ventirad et ça fonctionne tres bien

Comprata la versione da 4 cm per favorire la circolazione d'aria nel mio paludario/terrario. Il prodotto è esattamente come in descrizione, logicamente per queste dimensioni non è possibile immaginare che generi un grande flusso d'aria, ma per la mia applicazione è risultato perfetto. Regolabile su 3 diverse velocità, tenuto a quella media per miglior equilibrio potenza/rumore. Sono abbastanza silenziose, questo tipo di ventola genera sempre del rumore, ma non scricchiolano o generano attrito, buona qualità di costruzione. Unica pecca da considerare è la lughezza del cavo, piu che altro la distanza tra le ventole e l'interruttore di regolazione. Si parla di circa 20 cm, avrei preferito qualcosa di più generoso. Facile volendo allungare il cavo, visto che le ventole sono alimentate solo con 2 cavi, basterebbe tagliare il filo e giuntralo con altro cavo adatto, ma sconsiglio se non si possegono gli strumenti adatti per isolare correttamente il tutto. Nel complesso mi sono trovato soddisfatto, un buon compromesso tra prezzo e funzionalità.

Ich hatte davon vor rund 2 Jahren 1 Sett gekauft, um eine Art Keller auf wasserfürhendem Boden mit geringem Strombedarf schlicht mit einem Aussenluftaustausch zumindest etwas zu belüften ... Aktuell läuft einer der Lüfter in Verbindung mit dem Geschweindigkeitsschalter, um einen ewig nicht benutzen Kamin - der wegen fehlender Abdeckung die Wand druchfeuchtet hat - gaaaaanz allmählich durch Dauerluftsrom zu trocknen .... An den 5 Sternen lässt sich bereits erahnen: ich bin positiv überrascht. Punkt. Bisher halten der, bzw "die" Lüfter durch - teils laufen sie einzeln, teils beide - ohne die geringsten Auffälligkeiten ... Betrieb erfolgt über ein USB- Netzteil ... Und das unter relativ feuchten und ganz sicher nicht klinisch reinen Bedingungen ... Wer also eine günstige (Versuchs-)Lösung für eine unauffällige Dauerlüftung sucht: gefunden!
