Dual 80mm USB Cooling Fan 10-Speed 5V/DC 12V Terrarium Computer Router Xbox | Waterproof 16dB low noise fan for gaming, AV, receiver, console, external exhaust. 10-speed, USB 5V/DC 12V, ball bearing

These little fans are great! I got the "dual fan" type, and I'm using it as a little bitty window fan for a window that doesn't open far enough or have enough of a sill to put a big box fan in. It doesn't move nearly as much air as a big fan (obviously), but it moves an alright amount. I wouldn't recommend using it to blow on you in the summer since it's small and it'll only cool part of you, but it will blow hot stale air out of the room and get fresh air in pretty decently. It runs pretty well off a USB phone charger block, but adding a USB to 12V barrel plug adapter between the same charger and the fan speeds it up considerably, so you should probably get one of those to go with it. It's on the noisy side and definitely louder than a Noctua PC fan, but it's not bad.One gripe though, they've put the same logo sticker on both sides of the fan, which makes it harder to see which way it's going to blow. I keep putting one or both in backward and having to flip them. Either turn them on and feel before putting them someplace, or look carefully. It blows out the side where you can see the red and black wires going from where the cord goes in.

The noise level on these are very low. The performance allows the air flow to have great cooling performance. Installation is straightforward, just hooking them up to a standard USB makes versatility easy and straightforward

Well-made and waterproof and MOVE AIR. My application was different. I use them mounted to plexiglass on a window vent for my campervan. Works like a charm and pull very little amperage.

Fans are cooling down my routerThey work flawlessly quiet fanI’m very satisfied

I got this for my ikea Rudsta wide greenhouse set up. Been running nonstop ever since I installed it. For the one at the top, I used a strong magnet that has a hook attached. I also hooked it with another magnet piece on the metal back side. So the fan is slightly looking down on a slant. Please note the two fans are CoNNected! I put one at the top and one at the bottom(also laid this on a slant for better circulation). Now I need another set on the other side but my plants are still happy though with two. I refused to make a hole on the cabinet so at first I just let out the cords through the gap at the bottom of the cabinet door and fixate them somewhat to the inner corners with black wire tape. But you can buy a flat cord extension piece to plug everything and let that one line out the door through the gap fyi.

I bought these for a miniature indoor greenhouse that I built that fits on a table. They circulate the air nicely, barely take up any room and the adjustable fan speed is nice. They make only a small amount of noise which I can't hear at all with the box closed. I would definitely recommend these dual fans. Great quality!!!

A must buy for eletronics, i used it to cool my modem and router, my modem would get hot, it has vents not sure if it has a fan or not, but it would get really hot to the touch and would overheat sometimes, it nownstays cool even on the 2/10 speed using a 5v usb not the 12v, I can't hear it but it keeps my modem and router cool 10/10. Used it ro replace my old one from ac infinity which started to make noise after 3 years of 24/7 use it was gunked with dust and oil from cooking I guess, and it started making a buzzing/ grinding noise so I decided to replace it. And I'm glad I did, quitter 1-10 settings, 12v connection unlike the acinfinity fan, which had just high medium low and no 12v adapter.

These little guys have been going for a couple seasons now, as I use them in a makeshift greenhouse to start my pre-spring seedlings. Easy to create directional airflow as these are reversible, which is a plus. Best feature is that they have held up at different moisture levels and are responsive to being on a timer, starting up at the same set speed. Highly recommend.

It turns on. It's adjustable. Unsure if it's actually water proof.But I found when testing it, moving the cable would stop the fans. Not always, and not in a predictable way. Like a broken phone charger that stops if you slightly bump it or move it. I hope this doesn't effect them too severely in the long run but we shall see.

Had this product just a bit over a month. I have the dual fan version. The one of the fans now stopped working and the other fan fluctuates is speed most likely caused from the short of the other fan. I have the fan mounted to cool an aquarium. It is nowhere near the water and not exposed to any condensation, besides, the fan is supposed to be IPX rated for it.
