Wathai Cooling Case Fan for Receiver DVR Xbox TV Box Router 120mm x 25mm 5V USB Power

I bought this to be the fan under my mini computer. And if it's perfect it runs perfect. I got it plugged into the computer and when it's on the fan turns on and when the computer is off the fan turns off. It looks amazing. It's quiet. It's worth every dime. And it fits my mini computer perfectly.

I don't use the power controller, i just plug it straight into the mini pc and it will run whenever the pc is turned on.When using it as is, very quiet, effective cooling so the mini pc noticeably reduces the stuttering rate when streaming 4k movies.Very light vibrations but i don't think that will affect the pc at all when placing directly on top of it.The wiring is very thin and susceptible to damage if you yoink it unintentionally (see second pic) recommend to use hot glue to keep it in place.

One thing to take note of. When ordered the description calls out 5v usb power. When I got this the included user manual calls for a 12v 2amp power supply. Most 12v power supplies are wall chargers that use a barrel plug that needs to be removed. The fan side usb connection will need to be removed as well Another option is a usp swap for the barrel plug. Don't know why this change happened. There's no mention of the 12v 2A power requirement untill you get the user manual. Update, ordered a fan from a different company. It included a 5v usb supply with included fan speed control. So much better than this fan.Update, decided to try a normal 5v charger with this fan and it's working well. Still don't know why the manual called for a 12v power supply. I have it running to cool my modem. Will update if anything goes wrong. For now it's working well and perty quiet on the medium setting.Last update. It's been some time now and things are good. The wall chargers is still cool to the touch and the fans are still running. The modem is much cooler than without the fans. Normally warm but pertty cool now.Good quality great price, I can definitely recommend it after you get past the power supply misunderstanding.

I bought these to keep my Wyze Pro Ethernet Router/Mesh cool, since their fans alone were not very effective, and while it does that very well, the hum they produce even on lower settings is constant, and I can hear it when I'm alone in the quiet room. It's fairly minor, but I wish it was near silent at the lower speeds.

This little guy does make a difference. Highly recommended.

Stops my Roku from over heating. It quite and does it job. Super easy to install. Definitely worth the money.

Brought down the running temperature of my Mac mini M4 instantly. It is well made and sturdy.

Solidly built fan. I’ve been using it for a few weeks to cool my Eero router that runs very hot. I have it on the high setting 24/7 and rarely notice it. Definitely keeps my router cooler.
