ELUTENG USB PC Computer Fan 140mm with 3 Speed Adjustable, Dual USB Cooling Fan 5V 1500 RPM Computer Cooling Fan with Black Metal Grill for PC/Laptop/TV Box/AV Cabinet/PS4/Router

I got these fans to use in a TV stand to exhaust from a series X as ventilation was inadequate.They have good airflow and 3 speed settings and are easily powered via USB with a cable length of about 0.5m. In terms of noise they are fairly loud, not noticeable when gaming or watching TV though, but if noise is an issue then I wouldn't buy these.

Good for my needs. Have an investor for my solar panels in the house and I've automated the fans to go on when it's under load or if the sun is doing its thing. Good cooling abilities, decent size, overall good performance and brilliant value for money.

I bought these to place on top of my original Xbox One which is housed in an AV cabinet. The cabinet has doors on the front so the Xbox used to get very hot when working under high load and the fan would go into overdrive (usually this happens when switching between games) so I have to open the door to let some heat out. Since using these fans the Xbox fan hasn't gone into overdrive not once.Like other reviewers have stated they're certainly not silent but not so loud that you can hear them over the sound coming out of your speakers. It's actually a good thing that they make some noise because once I have switched everything off I can hear them quietly whirring away so it reminds me to turn them off (as they keep running when plugged into the USB socket even when your console is off).All in all they do what they are supposed to do and have solved my problem so well worth the money.

Using to cool router/ TV box.Good quality, quiet and working well .

On the lowest of 3 speed settings, there is a barely perceptible whirring sound - but you really have to be listening for it and it does not ever get obtrusive. Bought to cool down my CCTV DVR player which kept on cutting out due to overheat. A new hard drive and these fans have done the trick - the DVR box (running 24/7) is now cool to the touch and working fine.

I bought these as they were much cheap(er) than the "proper" setup from AC Infinity. My system is as follows:-Enclosed TV Cabinet, glass front, 2 shelves. No vents apart from 1 3" hole at the back of each shelf for cables to pass through.-Xbox One X Top Shelf-Marantz AVR Bottom ShelfThe reason I was looking for fans is that with the door closed, the Xbox One X will shutdown with a thermal protection message after around 1 hour of playing games. Also, the Xbox fan runs at full speed to try and fight a losing battle. When you open the door, a wall of heat rolls out to meet you. Not good.The good news. I installed the double fan unit from ELUTENG inside the cabinet. One fan draws cool air in at the bottom shelf, the other blows the hot air out through the hole at the back of the top shelf. After testing for just over an hour, the cabinet was nice and cool and the Xbox One X fan was on low speed throughout the test so was nice and quiet. So if you need to cool a cabinet down and don't want to spend more than a tenner.. These will do the job.HOWEVER (you knew this was coming). Before purchasing, I browsed the reviews. Some said it was "virtually silent", others were that it was noisy and they have to switch them off when watching a movie. Here is the first problem. There is no switch, you have to physically unplug them to switch them off. The do not have any thermal sensors so they are on full speed all of the time. To be fair, this is exactly as described this is how they are supposed to work. I plugged mine into my Xbox One X USB port. Unfortunately, this port is powered even when the Xbox is off so they run all of the time (again as advertised).The problem is the noise. Now here is the second problem. Different people have different opinions on what is loud and what is silent. I thought I would try and help anyone else thinking about these fans by comparing them to something similar in noise so you can get an idea of how noisy they are without me just telling you super silent or noisy.Bear in mind my fans are inside an enclosed cabinet with the door closed, against a wall. All the airflow is at the back of the cabinet.Here is what I think of the noise level1. Instantly noticeable when you walk in the room with nothing turned on.2. My wife also noticed it when she walked in "what is that humming noise"3. If you drive, about the same noise as having your car fan on level 2 of 44. If you have a PC, about the same as a graphics card fan on full speed with you sat next to the PC5. Slightly louder than an Xbox fan on full speed, with the xbox sat on top of a tv cabinetI build PCs myself and I'm quite sharp on fan noise as I don't like it. I recently replaced some fans that had worn bearings because the increased fan bearing noise was annoying. These are brand new and I'm not suggesting they are poorly made but they sound like a 3-5 year old PC fan that has some bearing noise. I'm not talking about mechanical noise,I mean the kind of white noise, air flowy, windy sound that a noisy fan makes.But they are a tenner. There's nothing in this price point that runs on USB power AFAIK that compares to them as and I mentioned earlier, they work really well at keeping an enclosed TV cabinet cool. Personally, I can't live with the noise so I'm going to return them and rethink this. There are solutions as mentioned by the big boys AC Infinity. Getting this kit in the UK is a challenge and you may have to import. Another solution would be the USB kit from coolerguys on here they sell pretty much equivalent stuff. I'm going to get a USB fan controller with a thermal sensor so the fans are not on all of the time (these may even work with such a controller, not sure might be worth a test before I send them back). All of these is going to cost at least 5-6 times the price of just these fans so its hard to complain.Bottom line: If you want a simple setup and not bothered about noise, on all the time. These will do the job.

Expected 2 fans and got 4 and is working very well thank you

Not used them yet, but they power up OK.Thank you.

Ik heb deze set ventilatoren op mijn hometrainer gemonteerd waardoor er een lekkere koele wind langs mijn hoofd en lichaam waait tijdens een intensieve training. Gebruiken heel weinig energie waardoor deze heel lang te gebruiken zijn met een 5 volt oplaadbare batterij. Ook handig dat alles al aangesloten is op een 3 standen schakelaar met USB A steker.

I'm very impressed with the ELUTENG 2 in 1 Fan 80mm 5V USB Fan Mini! The quality is excellent, and the three-speed adjustable feature works perfectly for keeping my PC cool. The fast delivery was a pleasant surprise, with my order arriving ahead of schedule. Highly recommended for efficient and reliable cooling!
