Dual 80mm USB Speed Control Fan, 5V Portable Cooling Fan for Flat-Screen TV Receiver Router DVR PlayStation Xbox Computer Cabinet Cooler

Works just as expected

I used these fans for my greenhouse cabinet. Functional and works like I hoped! I bought them again. Perfect size for small plant areas, easy to place, and quiet noise.

Keeps stereo cool ,no worries using it watching movies all day!

I got this for my router during summer to keep it cool and worked really well. With two fans it covers wide area.

I have an Asus Wi-Fi 6 RT-AX88U router that works great, except when it doesn't. After trying many things, I decided that the periodic rebooting might be caused by operating temperatures. I changed the factory firmware for the AsusWRT Merlin so that I could expose the operating temperatures. On the surface, the temperatures didn't "seem" too high. The CPU temperature was running in the 60's Celsius range for temperatures, and the 2.4 and 5.0 Ghz bands were running in the 40's and 50's respectively. Doing some research, I read others having stability issues clear up by introducing a dedicated cooling fan.I purchased this product and immediately noticed a reduction in overall operating temperatures for the device and over the course of the next few weeks, the stability of the unit improved drastically. As of this review, the current temperature readings are:Legend: 2.4 GHz - 5 GHz - CPUCurrent Temperatures: 37 °C - 43 °C - 50 °CThe CPU temperature is running at least 12 degrees cooler than before. I had observed previous peak CPU temperature as high as 67 °C. Now, it never breaks out of the 50s. The Wi-Fi temperatures remain equally cooler than before.I am running this unit on the medium speed setting, and I cannot hear it in the room running. When at high speed, I could hear it a little bit. For my installation, I have one fan running on the top of the router pulling air through, and the second fan underneath pushing air into the unit.In short, I strongly recommend this product if you have a need to add, or supplement cooling, to reduce operating temperatures. If it is for your router, networking gear, or an entertainment enclosure, this device will fit the bill as a quiet and effective solution. I have the fans powered by a dedicated USB power source, rather than being plugged into the router itself.

They fans work great for what i got them for.To cool my mini pc an onexgpu ,they keep them cool an on medium an low noise

These are multi purpose USB fans withe three speed settings. While they are designed more for cooling a cabinet that has music/video players inside, they also function as added cooling for your computer tower.Nowadays computers can get pretty toasty with the high wattage GPUs, so I decided to slide these fans into my case to help get even more air flow through the case. I put them in a position to pull more cool air inside and if I'm playing a fairly intensive game these little fans have helped drop the temps 10-15c at peak hot spot temps.The fans have a single controller and single USB power plug, so it's easy to attach it to your system. With a simple flick of my finger I can turn the fans on to low/medium/high, I typically keep in on medium but even on high they are not that audible when inside the case. They also have rubber feet so they stay in place nicely.It's far cheaper and easier that installing additional fans in a case, plus these having the added bonus of being able to be used elsewhere if need be. So far I'm happy with the purchase and hopefully they last a while.I'll update this review if I run into any problems down the line.

This is by far the best fan I bought. It’s whisper quiet even on medium setting. What’s great about it is that it stays on even after power is interrupted without need to manually turn it on again. Highly recommend.
