    Works like a champ!
    It runs quiet and cool. I used one to attach on to my Raspberry Pi 5 enclosure as an external fan to blow air towards the inside of the Pi5. Before I installed this external fan, the Pi5 CPU temperature reaches as high as 154°F. With the external fan ON at its slowest setting, the CPU average temperature is 93°F. That’s too low operating temperature so I use a smart switch controlled by a Home Assistant automation to turn ON the switch if the CPU temperature gets above 140°F and turn the switch OFF if below 110°F. BTW, this Pi5 is my Home Assistant server!

    Great all-purpose fans
    This is a great standalone item for all of your USB-powered cooling needs. I appreciate how much airflow is done through these two fans and how quiet they are. I’ve used them paired up at my desk to help keep the air circulating around my office, and also have used them outside to keep some airflow over plants and animals. I appreciate how you’re able to use these both at the same time using the 3-position toggle splitter, or use them individually off of a USB-A.One thing to note is that they do perform better based on the power source voltage. These spool up better when running off of my laptop’s USB versus a 5v phone USB charger. Overall not a big issue, just something to keep in mind.

    Quiet fan, needs longer power lead
    I had a project requiring a dozen or so of these fans (40mm). I used these for a CPAP hose dryer for my elderly father and it worked great.Fans are quiet, albeit not very powerful. They are really good for a low air volume application such as a 3D print filament dryer. Id give this 5 stars if it has a slightly higher rpm and longer cord

    Quiet. USB powered. Adjustable fan speed. Perfect.
    I love these fans. I have in my home an area in the wall that houses all of my Internet components I noticed that it heated up and could have been responsible for having my modem router burn out. I installed these fans one on top one on bottom of the cabinet. The airflow is great. The entire cabinet remains very cool. This was a great purchase.

    Solid USB Fans for Indoor Cooling
    These small USB fans quietly move enough air to lower temperatures in tight indoor spaces like electronics cabinets. After installing them near the vents of my entertainment system, I noticed the heat inside dropped a few degrees, which helped keep everything running smoothly. They’re surprisingly quiet — you hardly notice they’re on. The USB power setup is simple, just plug them in and go, no fuss with adapters or complicated wiring. The airflow isn’t powerful enough for large spaces, but for targeted cooling indoors, they do exactly what they’re supposed to do. Just keep in mind, they don’t have an on/off switch, so you need to unplug or add your own switch if you want to control them easily. Overall, a practical solution for cooling small indoor spots without noise or hassle.

    Great, quiet, low power consumption
    Nice and quiet. Perfect for my biltong box I’m building. Running off USB I can easily just put it on my power bank and run it for days- plus they’re adjustable
