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

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!

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.

Purchased for use with mini gaming pc. Much quieter than I was expecting! Exact size as my new mini gaming pc. Didn’t use the extension/power setting switch (but did test it and works great.) great airflow; cpu running much cooler.

This is the most powerful usb powered fan I could find for my project to keep cool my Dell Small Factor computer. Anything more powerful required an electric plug connection which I didn’t want. It’s relatively quiet and flexible with configuration to either pull or push air. The fan turns on when I power up the computer and turns off when I power down. It has helped with the other interior case fan to keep my graphics card temperature in the 50’s while playing demanding games.

I ordered this fan to keep my TABLO cool. The TABLO was running very hot. The size of this fan is perfect for my TABLO. And the feet that come with this fan make a good, stable base. It runs very quietly and provides a great amount of airflow! Now my TABLO is cool to the touch.

Day 1: Last night I rebooted my router after some outages and it was so warm to the touch I was feared it would catch fire. I purchased this stand, set my Xfinity gateway on top, now it’s cool to the touch… does it work better? Idk, but it makes me think so 😆. Quiet on the fastest speed. I wish I had a thermal image of before & after.

Worked out great to add airflow to my boat. Runs for ever on a large Dewalt battery.
