2Pack Quiet 80mm USB Fan Dual-Ball Bearings, USB Fan 5V, with L/M/H 3-Degree Speed Controller High Airflow Cooling Fan for Router Modem Receiver DVR PlayStation Xbox TV Box

I'm using this for my Xfinity modem and it fits perfectly. Nice and quiet and has helped keep the temperature down.

This fan is so quiet, even on at full speed. It has kept my wireless eero router nice and cool. Mind you, my router is up in the attic and this past week it has been around 100 degrees up there! Well worth the price.

I noticed that my modem/wifi router from xfinity was blowing a lot of hot air as if it was running too hot so i got this fan to keep it cool and man does it work perfectly for that! My modem runs a hell lot cooler now, i place my hand on the upper vents and you can barely feel any warm air anymore!

My Cox Wi-fi tower gets Hot! Purchased this New Hail 120mm Router Fan to COOL my WIFI. This fan was the perfect solution. Will buy again if needed.1. Came assembled (plug and play).2. Installation was simple and only took minutes.3. Plugged it into a Power Strip with USB Charging Ports.4. The top of fan is flat and level for a stable platform. Rubber feet raise fan for better air flow!5. (3) Speed Controller with off/on switch.6. Runs very quiet. Too quiet!7. No interfere with my wi-fi dual band signals

The fan perfectly fits my Kamrui miniPC! Although some of the reviews I read said that it was noisy I purchased the fan at risk. However, this fan has a reasonable volume and is absolutely quiet! I only have two negatives: 1) the cable shield does not extend through the fan frame (see photo) which allows additional stress on the power wires which risks their fraying/breaking; 2) not being able to easily decrease the height of the feet. I believe that cooling efficiency may be increased by lowering/halving the space between the fan and the device being cooled.

My Xfinity router would get so hot that you almost couldn't touch it. The heat was intense. I started using this and even though it doesn't move a lot of air it is enough to not let the heat build up inside the tower. Now i can only barely feel the warmth on the top and sides of the router. Although it doesn't blow a lot of air it doesn't have to as it removes the heat not allowing it to soak up into the component and plastic housing.

very quiet, but doesn't put out a great deal of air

On a hot summer day, the Netgear Nighthawk gets very hot, so I mounted the hotspot over the fan and turned on the fan and hotspot, and I noticed that the hotspot functioned much cooler.

While these fans were designed for computer cases, I used them in a lovely cooling pad for my laptop. While not a perfect fit (lots of extra wiring) they were almost a direct replacement for the original fans. Adapting modern tech for something that is quite, old in computer life terms, is not usually this easy, but the whole transplant took less than 45 minutes. The advantage of these fans are that they are a smaller offering in size to most fans. These are about 3" by <1". A great fit for my cooling pad but a bit small for a computer case, well, most computer cases.

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.

This fan works well. It is not too loud and has 3 different speeds, which are in fact, 3 different speeds. It will work. The cord length is good, as it can reach where I need it to reach without the need of an extension cord.

These work on USB and the noise level is quite low, rather absent. Placed above and below my mini PC they provide enough cooling when used for extended hours.
