ELUTENG Dual AC USB Computer Fan 140mm USB Fans for Cooling 3 Speed Control | 12V Computer Fan with AC Plug for Laptop Receiver DVR PlayStation Xbox Desk Computer Cabinet Cooling

I use these to sit on top of a CalDigit TS3, which can get quite hot during SD card operations. This unit pulls the heat away very nicely. Fan speed is controllable via a corded switch. I am not worried about noise/quiet so much as I only use when necessary. I would have gone for the 80mm fans If I would have sensed how small these are. (I estimate these to be half the size of a deck of cards). BUT these are quite effective for their small size. Not the most aesthetically pleasing from a "clean desktop" perspective with the cords and such, but tolerable for my setup.

I bought this fan to put under my adapter because I can be hard on it. It keeps it cool while I am gaming and my heat issues with my gaming laptop have reduced significantly. It's easy to use, it's pretty quiet, and it does it's job. It has made gaming SO much easier and I love that it is helping my adapter last longer too.

These are fantastic fans for what I used them for! My Xbox was overheating. I added more thermal paste to the processor which didn’t help. My case wasn’t too dusty and my fan seemed to spin like it should. I was out of options until I bought these fans. I mounted them to my Xbox to help push out the hot air and my Xbox hasn’t overheated since.

This works great and I like the speed control so I can reduce when desired. Not too noisy but can be heard if on full.

I bought this to cool a thunderbolt dock and it works extremely well for that on low speed. The only con is that it is louder than expected, which would be fine if the dock was tucked under the desk instead of onto of it. On low speed it is about as loud as a fridge compressor and is louder than a very quiet dishwasher.

As for the size, it fits my laptop perfectly, and the pads keep it from sliding around which was a concern at first, but it's definitely not going anywhere! The fans themselves run off of a USB cable, with a slider switch from off>low>medium>high and barely make any noise at all. In fact, my own laptop's fans are louder. These things are BEEFY by the way, i use a pretty low-quality, unmaintained ROG Asus gaming laptop with a 1060 that usually heats to 91C. This thing bumps it down, at 70%-90% load, straight to between 68C and 87C. That's a pretty big improvement, if you ask me. Also the plug being USB is pretty useful. I put it under my laptop but honestly this thing looks pretty versatile, you could probably use it for other stuff too if you want. Very good cooling fans, would definitely recommend if your laptop overheats and slows down.

It’s fine. It’s hard to give this a rating. It works. It’s fine. It’s not extraordinary. It works to help keep a mini PC of mine cool since its cooling system is kinda poor.

Very quiet, power cord is a little short, but it works great. I'm using it to cool an overheating portable oxygen concentrator.

Use this to cool down my AVR and is work as advertised.There are 3 speeds settings and so far I use the lowest speed and it is still able to keep my AVR cool down after hours of use. Would recommend it to others.

I have a 4080 with two fan Arctic liquid cooling, I bought this because the CPU core gets up to 80C when playing video games at high settings. This helps bring it down to about 74C. I was so impressed at first that I was about to buy another one but just one seemed to be enough after working for a while. Its also easy to move around when not needed.

The fans work, simply connect to the USB. Easy, can be used for a laptop. They are loud on the highest speed, but what can you expect for $14?

Nice quality but a bit noisy a high speed despite this its good product

I bought this to stick behind a ps5 because it sits in a fairly narrow shelf. It runs off the rear USB port. Because it's a 5v fan it is pretty low rpm but it still gets the job done and isn't obnoxious and loud.
