💨 upHere U1204 120mm USB Fan with Adjustable Wind Speeds - Ideal for Computers, PS4, TV Boxes, and AV Cabinets Review

Fans don't move much air, but they're quiet and run with Roku's USB source and wireless router. Airflow is weak, but meets the need to keep the device's temperature low so it's inaudible. Not worth getting speed control, the difference in airflow and noise level is negligible and really not worth the cost and probably adds a point of failure.

Some of the fans in my computer case stopped working so I bought some new ones. Problem after removing fans. I couldn't figure out if there was 3 pin power. Anyway, short. Installed these bad guys, they use a USB port for power, they have a 3-position speed switch. I run them at full power, I can't even hear them, and heck, they're always leaking air.

Yes the cost is low the colors look great and easy to adjust but the 3 control speeds remain the same I set both to high and it doesn't blow enough Air. It feels like a gentle breeze, not a real fan. Pretty disappointed with the outcome of the product, I'll probably go back and buy something else. Unfortunately, I liked and wanted RBG lighting.

Definitely doesn't have double ball bearings. The picture they show is not what is inside at all. This is an ordinary ball bearing, only very small. This is probably why my review was removed as I showed a picture of a tiny ball bearing that didn't match their picture. Just feel the fan. Does it move in a different direction than the rotation? No, that's why it has conventional ball bearings.

These things are great. They come with metal filters on both sides as well as little rubber feet for all corners on both sides! They are quiet and low-vibration. There's more than enough air for what I'm cooling on low settings. The only thing I don't like, although it's not even worth half a star, is that there's no control over the color or anything - they just cycle, but I'm fine with that. Setting them to low or medium also dims the LEDs a bit.

Rubber feet aren't the most durable things you'll ever see. The way they are attached is the main problem. If you tighten the screws at all, the legs basically fall off. The screws need a larger head to clamp the legs. However, it doesn't matter if for some reason you don't really need legs. I only use them on router and Xbox. I just connected to my router as it is always on and set the speed to medium. In fact, air movement inside the router is pretty important. On high they're still not very…

3 speed fan purchased Installing the Ubiquiti UniFi system. Access Points, Bullet Cameras, etc. All of them work on POE. I bought a small 60W 8-port (4 POE ports) switch for each segment of my network. The switch pictured runs 2 UniFi cameras and 1 UniFi hotspot, as well as internet for TV, ROKU and Blu-ray, so these little switches will be kept busy. To keep those local switches cool, I needed a quiet fan solution that wasn't too noticeable. These fans are perfect. There is something to…
