I purchased this for use with a Black Magic ATEM Mini Pro. It's a video switcher with 4 inputs, and it the bottom tends to get hot. Purchased in 2020, it's been working like a champ. Of late I found that it's filling the cache, and then eventually fails. Sound is also cutting out. Checked the boards, and it's apparently a heat issue.Put these two fans under it, ran on low. So far, neither issue has not returned.I really like the raised rubber feat that allow for space for the fans to draw air, and then more space above so the device (in this instance, my ATEM) isn't sitting right on the fans. I'm thinking about getting a grill or sheet metal of some kind, as the 120mm fans are a little too wide ... the ATEM rocks a little.Whisper quiet ... on Low. Turn it up to Medium or High and I can definitely hear the fans. I only use Low, and therefore not concerned. I have to be in the video booth with complete quiet to hear them. Start a program? I can't tell.

Cools my radio. Very quiet

Like the flexibility of keeping it separate or together. Nice touch at providing the parts and screwdriver to assemble it. Variable fan speed is another nice feature.

I have a glass cabinet with lots of plants in it, and air circulation is really important. These were the best fans I could find for the amount I wanted to spend. I have these plugged into the same timer power bar as my grow lights and they've been running 8-14 hours a day straight since I bought them and are still going strong. Creates good air flow, I can see the leaves moving (and dust cruising around, but that's a me problem not a fan problem). Plants are happy, I am happy!

Me gustó este ventilador por sus medidas cubre bien el área de un router casero ya no se calienta tanto lo mantiene fresco , tiene un interruptor con tres velocidades pero con la primera velocidad opera muy bien , necesita alimentación de 5V , y es silencioso .

Es potente y silencioso. Yo lo ocupe para enfriar mi consola serie S y cumple muy bien.

Es buen producto y silencioso

I kept having issues with my Linksys WiFi router when using my phone outside. I would be connected to the WiFi but with "no internet" and a 6mbps connection. I'm not even far from the router, maybe 15-20 feet. It occurred to me that this only happens during the afternoon, never at night. I placed my hand on top of the router and the whole thing is hot to the touch. That can't be helping things I thought.I started to look for a "cooling laptop pad" with fans that I could set the router on, but everything is too big, overpriced, and very poor quality. They also ALL have LEDs that you can't turn off (The RGB fad needs to go the way of disco). Most of them break within weeks or months according to reviews. I was about to give up but eventually I came across items like this. I should have been searching for "router cooler" or "router fan".I put this under my router. I could also place it on top as an exhaust. Then again I could always buy another one for the top too, maybe even the smaller 80mm version. It elevates it some but I'm not worried about it falling off because the nice rubber feet provide a nice stable base. I plugged it into the USB storage port on the router and set it to medium speed. A few minutes later I felt the top of the router and it's about room temperature, as if it's not even turned on. Now when I go out back and sit in my chair I get between 40-100mbps instead of 6mbps (with a ! for no internet). 40mbps might not sound fast, but it's infinitely faster than "no internet".Years ago I had a Netgear dual band router that I was trying out. It worked great until I had the brilliant idea of stacking it on top of the ISPs router/gateway/modem to save space. By the next day when I noticed how hot it was, the 5GHz band was completely dead. This was now a single band 2GHz router.I've also used a TPLink router that has similar problems. Even though I avoided placing it on top of other hardware, and even elevated it more using some blocks of wood to increase airflow underneath, I still had flakey internet and very warm operating temperatures. Basically this is a problem with all routers, especially if you have alot of devices and use internet nonstop.It sounds crazy to say it but this small inexpensive upgrade will extend the life of your hardware, and potentially even improve network performance. Good routers are not cheap. You can spend your money on an extended warranty, but I think your money is better spent on this item to protect your investment.This features 8 rubber feet , 2 fan grills, and a 3 speed + off fan control switch all preinstalled. The fan is a double ball bearing fan according to the specs, so hopefully it will last longer than a cheap sleeve fan. The fan is 120mm, which is big enough to move air without running at very high RPMs which means it runs quietly.The only thing I have that is close to a complaint is more of a request. Make this a $5 kit that comes without the fan. Sell us the rubber feet, fan grills, and power cable with speed control that is compatible with 4 pin (PWM) and 3 pin fans (non PWM). Let the customer decide what fan to use it with. How cool would my router look with a nice tan and brown Noctua fan sitting on top or underneath (or both)? Very cool.

Silencioso, excelente para refrigerar

El ventilador es excelente, tiene muy buena calidad.

Al principio no funcionaba uno de los ventiladores, tuve que darle vuelta con la mano para que empezara a trabajar. De ahí todo está bien, las velocidades que le puedes poner al ventilador son muy practicas.
