2Pack Quiet 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

These fans might be just as good or almost as good as the AC Infinity brand but I did originally leave a one-star review because shortly after the return window closed, I had problems with one of the two fans. One of the two has a bearing going bad and makes a terrible noise so it's unfortunately garbage. The other fan has been working fine 24/7 and show us no indication of having anything wrong with it. The reason I changed my review rating from 1 to 5 stars was simply because the seller reached out to me after the return window was closed and offered a refund. I wish more companies were proactive like this. I would have actually contacted them before writing the review but I didn't want to deal with returning the single fan and having to remove the second fan so I could return them both and get a new two pack. I really appreciate the seller reaching out to me and offering the refund and will likely pick up another two pack in the future if I need them. Worth a try but if you do have a problem I'd suggest reaching out to the seller if it's past the return window. Maybe I was just unlucky and got a bad one. They're ultra quiet like the AC Infinity fans, use almost no electricity, and keep my equipment significantly cooler.I'll come back and update this review again if I have any issues with the one that's still working fine.

I Initially bought these NewHail 120mm fans to cool my T-mobile Internet gateway since it was always very warm on top. I placed the fan at the bottom to blow cool air up, through and out the top and the fan did a great job of that. Gateway was no longer warm on top but very cool.T-mobile internet did not work out (no fault to the fans) so I went back to crap-cast for Internet. I now have these fans sitting under my cable modem and keeps it very cool. I liked it so much that I bought more and have my router and Roku sitting on one keeping them cool as well.Is this necessary and an over kill? Probably but at least the cable modem, router and Roku are cool to the touch now. :)I have them set on medium speed and can't even hear them running when my computer is on. With my computer off and in a completely quite room, I can barely hear them 3-4 feet away from me.They have rubber feet on both sides so can be positioned on either side and no vibration sounds.Everyone's ears and tolerance is different but for me, these work great!

I have one fan plugged in all the time and running on low. I like being able to adjust the speed. I have and ATT small router that runs off a cell phone signal. It works good, except it over heats all the time and shuts down. Since I put one of these fans on top of it, it stays cool and never shuts down.

Using for dog partition in Jeep. Very quiet and works great.

Edit: Sep 13. Updated ton5 stars. Been using these for a while now. One is attached to a side-mounted laptop holder. I have it blowing air through the vents to supplement the laptop cooling. It's still really quiet and is doing a great job.The other is supplemental cooling for a PS5 that's in an entertainment center cubby. It's doing a good job as well.Item described as new when purchased. What I received was obviously a return. The fans were not packaged correctly and it was missing the USB splitter.Update: Just received the replacement set of fans. All components in the box, factory packed, and clean. Plugged them in to test and they seem to work well. They are whisper quiet right now.Leaving 4 stars as I want to wait to see if they will last in their intended use case. But, I'm sure they'll be fine.

Works great, keeps my router cool and is very quiet.

good

I can’t believe how picky fan buyers are… “They’re not silent” “They’re USB” “They don’t move enough air” and on and on.Listen folks, the description is accurate. If you didn’t want what it says, then why did you buy it? Some people just have to complain. These are excellent. They are almost inaudible on low, a tiny amount of sound on medium, and still very quiet on high. I could easily whisper over them on high.I’m using these on a microgreen rack that’s unfortunately in my living room for lack of space. Even on high these will be plenty quiet to not notice. They don’t get quieter than this… moving air happens to make sound. If you want 100% silent, don’t buy a fan. If you want mass amounts of air, get earplugs. If you want an AC wall plug, buy one with an AC wall plug. People.
