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

Using for car camping ventilation while sleeping in SUV. Made a $3 Walmart foam board piece that fits the rear passenger window when it's party raised. I unscrewwed the grilles and used them to mark where to cut holes for the fans, then mounted them, Easy peasy. Mid speed very quiet, high speed noticable but only because they will be a mere 2 1/2 to 3 feet from my head when trying to sleep. If it works well I will use the foam board as a template for an ABS board version.

Quiet. I have several external NVME SSDs that i use for backup. They all overheat and fail on large backup transfers. I just sit this fan on my desktop and set the drives in front of the fan. It moves enough air to keep the drives cool so now they all succeed on large transfers. Nice that this comes with 2 with 2 separate controllers. Other similar fans that come in a 2-pack only have one controller.

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

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

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 contacted the company for their lack of quality control. They sent me one of the fans, new in the box, completely missing a rubber leg. I really needed the fan so I just put it in place until I can purchase another one or they respond and send me the missing component. I will update my review if they do.The fans do work nice, they are quiet running in an occupied TV room and seem to be providing good airflow for the components I placed it under. I used a powered USB hub to power 4 fans without issue.

Bought a pack of two. Needed a fan to cool off a tablo TV recorder that gets hot when in use. Bought this over a year ago and the same fan is never turned off. Still running as of today and keeps the tablo very cool. I was so impressed that I am buying this product again just to have it in case!
