ELUTENG 120mm Fan With 3 Speed 5V USB Powered Case Fan 1500PRM Gaming PC Portable Cooling Suitable for Tablet TV Receiver Router DVR Play Station Xbox Computer and More

This is exactly what I needed for my miniature home lab setup. It easily attached to my 3D printed “server rack” and provides the airflow I needed. It’s not the fastest fan, but has good speed and airflow for the 5V of power is consumes.

This really is a great product. Especially for the price. It’s a breeze compared to my old setup. Before I came across this gem, I’d been using just a regular old computer fan that I’d yanked from Dianne’s computer and an old camcorder battery I kept from my days working on adult films. It didn’t have any fancy settings or any of this newfangled protection they put into everything nowadays. It was either on or off and if I grabbed it while it was running, I nicked my fingers and that’s just how it was, until I found this product. It’s a little bigger than my old fan, so it fits snuggly into my back pocket, with plenty of cord to reach my new power bank I keep in my other pocket or my satchel, and it keeps the air moving. The HML switch is small enough to fit through my belt loops and with some planning, the cable can easily be strung through my belt loops keeping the switch conveniently placed at my side for easy access. Stringing it through my belt loops also keeps excess cord from being snagged by my flailing arms or those damn doorknobs Dianne insisted we get when we remodeled our home last year. I couldn’t believe how great the HML controller is for quick and easy control of the fan speed. The different speeds are great for a variety of cases. The lowest speed is great for just keeping the air flowing and keeping my pants cool and dry while the highest setting is great for quickly dispersing increasingly pungent smells. And it’s so quiet. Even on the highest setting, the fan remains silent. No more awkward “what’s that humming noise?” questions from people I got with my old fan. If it weren’t for the constant cool breeze, I’d forget it was even there. The grates on both sides are a MUST-HAVE. I thought I would just take them off, but they really do provide great protection on both sides of the fan. I no longer nick my fingers when I remove the fan from my pocket when I forget to turn it off. I haven’t had to put a new bandaid on my finger in days. And no more awkward fidgeting trying to readjust the fan in the heat of the moment after it’s become snagged on the pocket lining. My old fan constantly got caught up on my pocket lining. But the grate keeps the lining away from the fan blades no matter what. And the grate is strudy, too. Only the one time have I managed to depress it far enough that it came into contact with the fan. But, that was only because I accidentally sat down on the metal bleachers at Mathew’s baseball game with it still running in my pocket. But, even then, the grate bounced right back and didn’t bend at all. It’s still as straight as a rabbit’s ear on the Fourth of July. I’d recommend this product to anyone looking for a pocket fan. I like it so much, I’ve already purchased one for work, one to keep in my pickup, one to keep in Dianne’s car, and even one for David because I know he’ll just love it. There’s nothing better than having a cool crevasse in the heat of summer, being able to disperse those wrank bouts of gas after Dianne’s world famous enchiladas, and warm apple pie. Just the other day, Dianne and I were grocery shopping. I let one slip in the produce section down there at the Walmarts. I flipped the switch to high and in a matter of seconds, it was a row over. The poor girl stacking the carrots started gagging because she thought some of her produce had gone bad. But no one looked at me for a change.

I bought 2 of these- one to put on top of my Fios router, that seemed to be running a bit hot, and one to put next to a Surface Pro laptop that I'm using as a Plex server. The fan fits perfectly on top of the Fios router, and it quiet, on low. The other fan I put on medium and sat it on its side, and let it blow across the Surface Pro. It works well and keeps the temperatures down. So why 4 stars? One of the fans started making a weird slight vibration, which made it louder. I couldn't get it to stop, no matter how I propped it up. I had to swap that fan for the one on the Surface Pro; the router is right in the living room, but the Surface Pro is in the basement, where noise doesn't matter as much. One other note- you'll need a USB-C adapter if you plan on using this for a Fios router.

If you're looking for a fan that has a decent wind strength where it blows enough air, this is not it (it is very weak if you want something for that, even in the highest setting the wind is weak). But for cooling it does the job. I prefer it a lot and fits just my needs as the wind isn't too strong but it cools really well. Planned on using it as a temporary cooling for my pc as the top fan broke, but maybe I'll use it for a bit unless if I move my pc where it is visible (currently under my desk). I have it on the highest setting, my pc is not hot anymore. Another great thing is that this fan is super quiet, I don't even notice it's on. Maybe if you have it somewhere near you or in a very quiet room you may hear it, but it's not noisy.

Works great. Keeps my mini pc cool

Quiet

I bought this to cool down an AT&T NVG599 modem and router combo that I noticed would get very hot with incredibly slow wifi, requiring a daily reset. I looked inside the router and saw that there was no active cooling at all, only two heat sinks with no airflow. Putting a fan in front of the router seemed to fix the wifi lag, but the only fan I had was big, loud, and probably used too much electricity to cool a single router. Due to the terrible internal design of the NVG599 modem I had to set the fan to high, but the fan is very quiet even on high when placed in my living room. However, It might produce a humming that would be noticeable in a small and quiet bedroom. It's totally irresponsible that companies design wifi routers without active cooling because hot routers are a real issue that leads to slow wifi, but I can see why ISPs would be motivated to cut this particular corner. Whenever I've asked technicians from AT&T and Verizon that have come to my house to service my internet they found this idea to be ridiculous and blamed it on my cheap internet plan. But from my own experimentation, I know that router heat is the real issue because Ethernet connections work fine and wifi is still slow even when testing the speeds right next to my router. Before you shell out more money for subpar internet from the big ISPs, give this fan a try.

The fan is decent enough, through I didn't need three speeds. Even at the highest speed, it's fairly quiet. That it moves only 56 CFM at best is why it's quiet. Very little turbulence is involved in the fan's operation. The thing is, I didn't buy this for a computer or for cooling. I needed a USB fan to be the "suction" part of a UV gnat trap. I was seriously concerned that the fan itself wasn't powerful enough to suck in the gnats attracted by the nearby UV light. I compensated for that by decreasing the size of the entrance, so that air is more quickly pulled in by the fan. In testing, I put it out, with fresh passive gnat traps, and comparing the two. The fresh passive gnat traps had a few stuck to them . The inside of the gnat trap looks like complete gnat carnage. So as long as one has a decent idea of air-flow mechanics, the fan works quite well to suck in and trap gnats. As a cooling device for a hot item, it does actually do that job, too. The UV light, when left on (as it needs to be) does get very hot. But with it positioned over the hole through which the air is drawn, it stays nice and cool, but it's VERY close to the fan itself (within about 2 inches from the intake), so I'd be hesitant to use a low CFM fan on a vital component in need of cooling without some real clear air-flow dynamics going on. I'm pleased that it worked for me. I'm even ordering another one to make another gnat trap. But I would get a much higher CFM fan for anything larger than a tiny UV light. The 120 fans I have in my computer have over 140 CFM (more than two and a half times the air flow of this) and they barely keep up on warm days. So consider carefully what you're trying to do with this fan, and your own skills at airflow dynamics, before you buy. UPDATE 09/03/2022: I purchased a second fan to make a second gnat trap, and found that the "silent" fan I originally got wasn't a repeat experience. The second fan has a grinding sound that tells me the bearings are already messed up. It has a surging sound that goes from almost silent to rather loud, to almost silent again, and it's really annoying in a quiet environment. For the lack of consistency in quality, I'm removing a star, going from 4 to 3. And if the bearing goes and I have to replace the fan, that will be a huge pain, because it's literally built into into the middle stage of the trap (the bottom is the vent and sticky trap, the top is an air vortex that increases the suction power of the fan). That means I'd have to rebuild the whole stage again around the new fan - it's not designed to be replaced easily. If it was going to make this much noise, I'd expect it to move a lot more air - and it doesn't. I'm removing a star (from 4 to 3) for the noise it makes. I'll revisit this review for a serious down-grade in the stars given if the bearing gives out, or the noise increases, in anything less than 50,000 hours of operation.

good powerful fan. a bit loud, but we run it to keep extra airflow around the xbox. I bought a second one as an exhaust fan for a biltong box and works amazingly for that. 100% would recommend

Es exclente trae 3 velocidades que si lonutilizas como extra en una consola o pc disipa el calor muy bien t se mantiene muy refrigerado el objeto, solo que si subes la maxima velocidad se nota mucho el ruido si estas en un lugar tranquilo

This is a great little fan! It's very quite, has 3 speed settings and it can either connect into a USB port or a regular outlet with a USB adapter. I use it to cool down my large Harman-Kardon stereo receiver. It sits flat on top of the receiver and makes no noise what so ever with the added rubber stick on feet! My previous HK receiver use to shut off when it got hot...not with this one!

En in inicio lo compre para enfriar una laptop, sin embargo lo utilizo en la actualidad para mantener fresco un amplificador de teatro en casa onkyo ubicado en un espacio reducido, cumplido perfectamente con el objetivo

Francamente es bueno, lo compre para colocarlo en mi PS4, no mejoro el ruido que hace el ventilador, pero en las pruebas que hice, enfría. Hace menos ruido que del ps4. No lo recomendaría para lo que yo lo use, pero quizás para tu PC igual y si. Si tiene 3 velocidades y el material es bueno, me gustó que viene con rejilla de ambos lados y que pude usar sus mismos tornillos para unirlo al PS4
