Review on 💨 upHere U804 USB Fan 80mm: Silent, Adjustable Wind Speeds for Computer, PS4, TV Box, AV Cabinet by Karoly Reddick

These things are great. They come with metal filters on both sides and small rubber feet for all corners on both sides! They are quiet and have low vibration levels. 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.
