AmRunJe 140mm x 25mm USB Computer Fan with 3 Speed Degree 5v PC Cooling Fan for DVR Receiver PlayStation Xbox AV Cabinet

Added to the CPU cabinet in my desk to keep the air circulating when the door is closed. There is a vent in the rear bottom of the cabinet but it did not allow for good circulation. Set fans so one is intake and one is exhaust and now the space stays cool even with the door closed. Super quiet too. And with the USB power, it goes off when I power down the PC.

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.

They Both work as said and I have no problem with them. They do make a little fan noise but nothing else. The 120 mm fans are a little more quiet. Otherwise very good.

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!

Works well for air movement. With 1 fan hooked up, it runs at 100% power. With both fans hooked up, you lose 30-40% power. It still vents my mushroom monotub well enough. Had to fashion a gasket because the fan guard (which i used) protrudes 1/4" from the fan. Good quality for 3 bucks and the 90% humidity hasn't been an issue yet.

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.

1 can came broken and the other was loud

These are nice little fans with a good usb control knob. I got it to provide airflow in my Kingsnake terrarium.
