Dual USB Cooling Fan 120mm

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.

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.

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

Hooks up to my USB port in the back of my vehicle. Low, medium and high settings all put out a really good breeze! Extremely quiet and super lightweight. Has been pretty reliable so far to help keep my dog cool while traveling and waiting at events. For a Ruffland kennel fan I recommend this and it’s affordable!!

So, I clearly wasn't paying attention when I purchased this, I wanted to get mini fans with a control for a little terrarium so I could circulate some air into the setup, this is a heatsink. At first one fan didn't work, it was due to the grill, when I loosened it the fan worked again. I decided to experiment with this mini heat sink and found that it is surpringly effective at looking phones while charging, even with screen down on the heatsink (if the phone has a case). So now I have a little charging stand with this cooler, it will wick the heat off a hot phone almost immedietly. Hoping this will extend the life of the phone batteries in the long run. It's been wicking the heat off of any device I am charging. Yes it is loud at full power, but I usually havea headset on anyway.

Ps4 no longer sounds like a jet engine taking flight, it really is very quiet and even running heavier games it's made quite the impact in keeping the system cool! I could almost see if you wanted a super quiet fan for your desk this would probably be just as great, it's that quiet and effective.

Purchased this usb dual fan set to ventilate my PC cabinet. Pretty awesome. Very quiet. I was very impressed.

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 good quality. Serves the purpose of cooling our wifi modem very nicely.

Works as advertised, it's pretty quiet and is keeping my server cabinet much cooler than it was before installing this fan.

Oh it's bigger then I expected wow it brought my drive disk temp down by 10° c so u can't complain just just on default speed. I can't complain Makes no sound no vibrations and a constant speed I am using its own USB dock and not a laptop or control bored USB. I haven't tested it's threw a ps4 port ps5 ECT..

Meant for a computer but if you have the crank windows in your house and you need to cool down your bedroom to sleep this fan does wonders.

The fans move a good amount of air for their size, however I dont know if I got a faulty set of fans but they make a grinding noise that is very noticable at the low or medium setting. The mode switch itself gets unusually warm when on the high setting, but thats negligable compared to the grinding noise. I originally bought these to cool my 5G Hotspot and laptop charger, hoping that a dual fan setup would be quiet enough on the low setting to not notice a few feet away. The grinding noise is audible unless in the high setting.
