NewHail Quiet 120mm Router Fan Cooler with L/M/H 3-Degree Speed Controller, DC 5V USB Powered Cooling Case Fan for Router Modem Receiver DVR PlayStation TV Box

Very quite.. they do not push a whole lot of air. I use them for some audio amps, they were not overheating but these keep them cooler and are not noticeable. They have a fan speed control on the wire. Just set it and forget it. They did not turn on with the y cable supplied for some reason but I didnt need a splitter anyhow. I may have needed to use a higher amperage power supply. They seem well made and I like the rubber "feet" they come with. They come with a surprisingly long cable.. about 3-4 feet for each fan i recall.. and 6 inch y cable. Perfect for anyone looking to cool something down.

Perfect size for my min computer. It works great with my GMKTec Ultra Mini i7-127H. The fan is whisper quit, even on the highest setting. It should be called The NewHail Quiet 120mm "mini computer" Fan Cooler.

Good size fans with decent cooling power. I use them under my Fosi V3 Mono amps. I was using 4” fans and they did a great job, but they are a little big for the V3 amps. These smaller fans are a little noisy on the highest power so, I set them for medium power. They cool the amps sufficiently.

If you have t-mobile's home internet 5g service, you might have the Nokia gateway, affectionately known as the "trashcan". That object of your affection has a tendency to overheat and throttle or slow your connection significantly. Keep it cool and the speeds and stability are great. My old setup was keeping the trashcan in a wired rack with a vornado fan blowing through the grates to keep it "cool". Wasn't efficient and the fan's drone finally got to me. These are perfect. The build quality is a very sturdy plastic. You can just simply place the gateway or router directly on top. A fan speed controller allows for adjustments which range from completely silent to barely audible. The 120mm fan ensures that there is enough static pressure / airflow to get into the bottom intakes of the gateway or router.

Great little fan that provides constantly cooling to the mini PC, especially those with with air intake from the bottom. I have it on max, and the noise levels is not as bad. It kept the PC cool between 5 or 10 degrees; the exhaust vent from the PC feel cool. The nicest feature is USB powered. It can be connected directly to the PC that can be powered on and off with the PC. The little prop up legs at the bottom gives plenty of air flow for fan to draw cooler air. I think the price point is fairly priced. Although, with positive things I've said what this little fan can do, there needs to be some QA inspection of the product to make sure the workmanship is up to par. Mine came with one screw losing and it was hard trying get the nut to hold in place in a small hole while crewing back on. You have to get creative if your device comes like mine.

I bought this for cooling my ARRIS SURFboard SB8200 DOCSIS 3.1 Cable Modem. It is just the right size for placing the modem on top of the fan and the selectable airflow speed cools it down perfectly since these modems typically run very warm. I just updated to the new ARRIS SURFboard S34 cable modem and this fan is just the right size for this modem too. I highly recommend you use one of these cooling fans with your ARRIS cable modem as the fan's cooling capability will allow the modem to perform better and extend the life of the electronic components inside the modem.

I am using this fan under a 3-4 lb modem that has a smaller foot print than this fan. The fan is 120 mm square and the modem is 100 mm square and the modem feet are 70 mm square so it sits on the grill area of the fan without pressing the grill against the plastic below it. The fan itself is much lower so even if it did press on the plastic below it would not appear to affect the fan. It seems like it could support a much heavier load especially if the load overlapped the edges or rested on the edges of the fan at 120 mm. It seems sturdy for its intended use. It is quieter than my computer and the mechanical switch is nice so I don't need to turn it on manually when my timer turns on and off the fan. I have read that some of the electronic switch fans you need to turn them on each time you restart your computer.

Hopefully they last.

Llevo usándolo en la menor potencia y jamás he sentido el router caliente nunca más, cumple muy bien su función y no se escucha el ventilador para nada

My ISP's modem would get hot enough that it was discolouring my wood desk's finish. Now it's nice and cool, even with this fan running at low speed. I bought a second one for my router. At its highest speed the fan is audible, but it's more of a low hum than the high whine you might expect. Virtually silent at its lowest speed. I have two running on my desk (modem and router) and I don't notice them.

Tres bonne achat, j en ai mis un en dessous de ma boite android ca baisse la chaleur de 16 a 20 degré pas besoin de percé de trou. L autre sur mon HD. le filage est long a aussi une switch off, low, med, high super silencieux. un spliter de usb si vous brancher les deux sinon les fan ce branche indépendamment. Un caoutchouc des deux bord ce qui fait que vous pouvez la mettre qui tire ou qui pousse . Je le recommande fortement.

Vraiment efficace et silencieuse . J'apprécie spécialement le contrôle de la vitesse qui contribue grandement à son silence.

My router doesn't over heat anymore.
