Wathai High Airflow Router Cooling Fan for Computer Cooler TV Small Box DC 5V USB Power 120mm 240mm Fan with Multi Speed Controller

Very nice cooling fan it has 3 speed low, mid & high + ON/OFF button as described. The cooling fan is working and high quality product. I will buy it again. I recommend to buy this item.

Exelente para aparatos como consolas o en mi caso compre 3 para mantener frio mi receptor, pues a pesar de tener 4 en el anterior se quemo, al parecer por defecto de fábrica, lo recomiendo y mas si le pones un apagador inteligente

I didn't want to do the work. And these folks have. I absolutely LOVE IT! Pros: It works like a charm keeping routers, laptops, YOU cool Examples: Wifi link in the garage gets super hot in the summer time. But this did the trick so my speeds are back up and connections are not dropping like they used to! I also use it on a verizon 5G wifi cell modem. It's like it was made for it. I also use it under my high performance laptop to keep it cool and this does it so so so well. No laptop fans buzzing all the time. Instead with two of these fans running in my office I barely notice them. The noise at best is white noise, but when you're working or on a call I would challenge you to hear them going. Cons: I am not a fan of the button control. I know why it was done this way, but I'm not a fan of it. When the power goes off, this won't turn back on. So that is a major bummer. I get away with it using UPS units, but a rocker switch would have made more sense. Instead of three speeds there's at least two and when the power blinks it comes back on when the power comes back on. Honestly I could change it myself but I'm so lazy lol These folks have done a fantastic job with this and frankly I'm sucker for folks willing to put in a little time to innovate something that patches a major hole in router and modem cooling. Thanks for making these, love it!

I'm updating my review to 5 stars because this fan works great, just not under my modem. After I had installed it under the modem, I noticed that my PVR box was also running hot, so I moved the fan and put it ON TOP of the PVR box. (I noticed that the PVR box only had ventilation holes on the top.) Beauty! This fan is SILENT when used in this application. Works like a dream. I only need to run it on the first setting to keep the box lovely and cool. ***** If this was under a modem in my basement I might not mind the hum. But it's in the corner of the master bedroom, and even my deaf husband can hear it running on low. I was initially very impressed that it came with speed control, but it's not silent on the slowest speed, so I'm not very happy with it.
