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

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.
