KEYNICE Quiet Dual 120mm USB Fan, 3 Speed Case Fan, DC 5V USB Cooling Fan, PC Fan for AV Receiver DVR PlayStation TV Box Computer Cabinet Cooling

I have an original PS4 model and recently we moved it into a game room that has a TV stand with slots for consoles. Unfortunately, there is a wall in the back and the slot gets really hot as the heat is unable to escape easily. It was making my PS4 run hotter and louder than normal and it was definitely hotter to the touch.I have these fans inside the slot. One is pointing to the back of my PS4 and the other one is angled to take the hot hair and push it out front. It has made all the difference that I had wanted and hoped for.While the noise level isn't great on these, it's a game room and it's not like I need it to be quiet, so it is what it is for me.So far, very satisfied with these and the air they move. I will see how long they last as that's the only thing that would change my rating now.

The media could not be loaded.  I surveyed window fan for a while, I couldn't find one the size fit my kitchen window. I ordered this dual 12" fan and panel to do DIY. It turn out pretty well. I set top fan to suck the kitchen warm air out and low fan blows in the outside cold air. The noise is acceptable for using in kitchen, I even can't notice that it was on. Compare the cost with 8" dual window fan, my design even lower. Its only failing is cable a bit short, you can find a way to extend it.

EDIT TO 1 STAR. After a few weeks, these fans are rattling worse than an Oldsmobile Toronado being hauled away from a demolition derby. And not one of the cool 70s Toronados....but one from the mid 80's with all of the rust issues. And the wildly cracked hard leather seats that Oldsmobile made in an attempt to copy the Chrysler Corinthian leather; and when it was cold it could slice through a Kevlar vest (or the seat of your pants). You know the ones.... where your mom put some old bath towels down on them in a feeble attempt to placate you as the squishy suspension sent you sliding across the seat with every small bump or pothole. But the towel never worked and now you need reconstructive surgery and skin grafts to repair your poor backside that was so mercilessly shredded by Oldsmobile.Anyway, these fans are like a busted old 1985 Oldsmobile Toronado. They rattle and will scar you, no matter how hard to try to love them.*Original review*Got these fans the other day to help keep some electronics cool. I have numerous other small fans like these that I have been using for years without issue.The two new fans function and blow air like they are supposed to. The overall operation of the fans is fairly quiet at low speed. The problem is that they are off balance somehow and will rattle if set on a hard desk. None of my other fans rattle at all, yet these things make the whole table have a minor (but wildly annoying) high frequency vibration that is both noisy and screws with your sense of touch. I had to mount them to a piece of foam just to provide some padding between them and the desk. But if you pick it up, it feels like hanging on to a mini reciprocating saw.With this 'modification' in place, they aren't bad. But I already feel like the bushings are going to give-up the ghost sooner than later.Overall, not really pleased with these. But the process of returning them is too much of a hassle. So I'll use them until they fail.

The media could not be loaded.  Used for moving air inside a greenhouse. I like the fans 💯%

I put these on the outside of a gaming computer just to move the air around because it tends to get really hot around the computer case itself. These fans move quite a bit of air so we're doing a great job and it's helping to keep the core temperature down several degrees which is very helpful. I would definitely purchase these again

I purchased this USB fan mainly to cool down the inverter of my solar system. I works great as I putbehind the inverter and close to the window. It drives out the heat from the inverter outsdie such theinverter wont' get too hard. I really like it's USB drive that I just plug in to my solar control USB portsthere you go !

A bit unorthodox, but I bought these to use with a couple of plant terrariums I have. They haven’t been set up for long, but so far they’re working really well. Very quiet, don’t take up much room but even on the lowest setting they’re moving enough air to keep me happy. The cord is decently long too. If I set up more terrariums I’ll buy more of these in the future.

I put these into a new cabinet holding gaming consoles. These come on quietly when the system is on and keep the interior much cooler.Seems common sense but have one blowing in and one as an exhaust and it will work great keeping things cool.
