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

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 coolExamples: 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 lolThese 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.

Works great! I bought a Tablo DVR which runs really hot (normal they say). But I want it to last so I wanted to cool it down. It fits perfect on this little fan. I have fan on low and the Tablo is cool as can be. No issue with noise. Only hear it if my ear is a foot away. The fan comes fully assembled, which was questionable based on the listing photos.

I use this fan to help keep my ARRIS modem cooled off; modem tended to get very warm to the touch….too warm in my opinion so I opted to try some supplemental cooling.Only issue…this is in a TV room so when it is quiet a definite background audible HUM from the fan can be heard clearly….for some maybe a reason to think twice but I prefer the COOL modem…

This works amazingly well. Quiet, comes with speed adjustment cable (Not Using) Fair Price and most importantly cools my CyberGeek Micro Computer to almost shutdown temps. System was glitchy and hanging up while preforming simple tasks (CPU Overheatig). Now works like a charm.

I’m not sure why people complain about this fan. It’s clear they do not understand what this fan is designed for.It’s not a “blowing wind fan”! It’s designed for a gateway or WiFi modem. A slow and steady push of air to move over the internal components of the device you put on top of of the fan.Example: there’s a chronic overheating problem with XB8 gateway that can cause component failure and even fires. I have put my gateway on top of this fan and the gateway is cool as cucumber since this fan slowly pushes are over the hot components giving time for them to cool and the internal cavity of the gateway to exhaust all the heat. This fan is perfect for this see my ohoyo to understand.

This fan works better than expected. Its super quiet and the usb runs perfectly. I set this up to keep my home router cool as it was over heating. I haven't had any issues since installing this fan. I would highly recommend this product.

This fan has been sitting atop my Internet Hotspot device and it has been running 24-hours-per-day for a few weeks now. -- It never heats up ---It has never failed except in a power outage --I can not even hear it running, it is so quiet ---I have to put my hand above it to feel the air it expels when I want to make sure it is still running --- This is an amazingly high-quality item and it was very economical to purchase and it uses very little electric ---and it keeps my electronic device cool -- I am always going to have one of these on hand and, in fact, I have a spare in my desk drawer just in case ..... but I doubt I am ever going to have to use the spare. I love this little fan....dearly love it!
