Most of the people that upload videos or TikToks of their cabinets have either these or similar ones, but these are the only ones I’ve tried. I have 3 in each cabinet - 2 pack & 1 pack connected by a USB adapter, and have them plugged in. They’re on 24/7 to provide air flow, and I haven’t noticed them creating any heat. The adjustable speed is nice too - I keep it on the lowest setting.The price is great for what they do, and I plan on putting some up in my Ivar to push air around so I don’t need to leave a regular fan on towards them. These fans are also super easy to install - I just use magnet hooks to hold them in the upper back corners and pointed slightly down. Zip ties would work fine too. They’re small enough to fit anywhere, so I could add more if I ever need to without having to sacrifice any space.Although I’m not using these for my computer, they work great for my plants!

These are quality fans. Not a darn thing wrong with them. If I didn't have three other fans by other manufacturers I wouldn't even know that they could be a lot quieter. I'm always amazed at how quiet these little fans can be. This one... not as much.This little fan is not noisy by any reasonable person. But it's not as silent as others. I can hear it hum (on Low) when my room is quiet.

Update 1/17/24: Still working perfectly, I couldn’t be happier.I have this atop a 10kbtu propane radiant heater on a temperature controller and it’s exactly right for my tiny cabin. It’s almost dead silent and I mean that, it’s vewey vewey qwiet. I run it on medium setting which is a perfect mix of sound level and air movement. Even on high it’s no where near as obtrusive as the wire frame usb fans I’ve used in the past.
