Quiet Dual 120mm USB Fan Dual-Ball Bearings, USB Fan 5V, with L/M/H 3-Degree Speed Controller High Airflow Cooling Fan for Router Modem Receiver DVR PlayStation Xbox TV Box

This plays perfectly with the Blackmagic Hyperdeck Shuttle HD, in case you're looking for a way to keep those running cool. It's exactly the right size, and very quiet... so quiet that I forgot to turn it off when I'm done after a digitizing session! Simple product, done well.

Great idea, HML speeds, quieter than the computer. Put this on top of the warm router, cooled temp down even on low. Didn't need to mount, and was very easy to use. The USB power is convenient. HIGHLY recommend it to those needing a bit of cooling--not for high CFM circulation.

I have these running 24/7 under my TP-link deco 7 elite router and satellites because they run a bit hot. The value for the money is not really beatable. I mean you can control the fan speed and it was easy to set up. It has a low, medium, high and off mode. I keep it running on low and have not had any issues. It also has great airflow.

Whatever you set on the fan is held only by gravity. Some type of clip or maybe even a rubber band around the unit and the target device would make it more secure. It is very quiet at low speed which is more than adequate for my function. Mini pc stays considerably cooler. It is well made for the purpose.

Works perfectly! I got it to fit under my hot router/modem and it cooled it instantly. I don't know why people say it's loud, because it's definitely not. On the lowest setting I can only hear if I'm inches from it. If it's on high then yes you hear a sound, but it's not even as loud as my furnace/ac/refrigerator when they're running.

The items arrived as described in prime condition. This product is easy to set up and works seamlessly with my UniFi U7 Pro XG and U7 Lite hardware. Both devices would previously get quite warm to the touch, but with this fan, they stay very cool and function exceptionally well. I highly recommend this product.

I am using this fan under a 3-4 lb modem that has a smaller foot print than this fan. The fan is 120 mm square and the modem is 100 mm square and the modem feet are 70 mm square so it sits on the grill area of the fan without pressing the grill against the plastic below it. The fan itself is much lower so even if it did press on the plastic below it would not appear to affect the fan. It seems like it could support a much heavier load especially if the load overlapped the edges or rested on the edges of the fan at 120 mm. It seems sturdy for its intended use. It is quieter than my computer and the mechanical switch is nice so I don't need to turn it on manually when my timer turns on and off the fan. I have read that some of the electronic switch fans you need to turn them on each time you restart your computer.

My WiFi box use to get super hot and wifi would lag, now it literally stays cool and WiFi is fast again. Highly recommend

Llevo usándolo en la menor potencia y jamás he sentido el router caliente nunca más, cumple muy bien su función y no se escucha el ventilador para nada

Je cherchais des fans silencieuses pour mettre sur mon système de son lorsqu'il s'allume! Je suis totalement satisfait! Presque impossible à entendre

Ventole silenziose, con velocità diverse, lavoro svolto efficacemente con abbattimento della temperatura d’esercizio a beneficio della funzionalità dell apparecchio. Spedizione veloce confezione ben curata

My ISP's modem would get hot enough that it was discolouring my wood desk's finish. Now it's nice and cool, even with this fan running at low speed. I bought a second one for my router. At its highest speed the fan is audible, but it's more of a low hum than the high whine you might expect. Virtually silent at its lowest speed. I have two running on my desk (modem and router) and I don't notice them.

Fanno quel che promettono, ma a ventole alte sono troppo rumorose
