240MM USB FAN

I didn't want to do the work. And these folks have. I absolutely LOVE IT! Pros: It works like a charm keeping routers, laptops, YOU cool Examples: Wifi link in the garage gets super hot in the summer time. But this did the trick so my speeds are back up and connections are not dropping like they used to! I also use it on a verizon 5G wifi cell modem. It's like it was made for it. I also use it under my high performance laptop to keep it cool and this does it so so so well. No laptop fans buzzing all the time. Instead with two of these fans running in my office I barely notice them. The noise at best is white noise, but when you're working or on a call I would challenge you to hear them going. Cons: I am not a fan of the button control. I know why it was done this way, but I'm not a fan of it. When the power goes off, this won't turn back on. So that is a major bummer. I get away with it using UPS units, but a rocker switch would have made more sense. Instead of three speeds there's at least two and when the power blinks it comes back on when the power comes back on. Honestly I could change it myself but I'm so lazy lol These folks have done a fantastic job with this and frankly I'm sucker for folks willing to put in a little time to innovate something that patches a major hole in router and modem cooling. Thanks for making these, love it!

One thing to take note of. When ordered the description calls out 5v usb power. When I got this the included user manual calls for a 12v 2amp power supply. Most 12v power supplies are wall chargers that use a barrel plug that needs to be removed. The fan side usb connection will need to be removed as well Another option is a usp swap for the barrel plug. Don't know why this change happened. There's no mention of the 12v 2A power requirement untill you get the user manual. Update, ordered a fan from a different company. It included a 5v usb supply with included fan speed control. So much better than this fan. Update, decided to try a normal 5v charger with this fan and it's working well. Still don't know why the manual called for a 12v power supply. I have it running to cool my modem. Will update if anything goes wrong. For now it's working well and perty quiet on the medium setting. Last update. It's been some time now and things are good. The wall chargers is still cool to the touch and the fans are still running. The modem is much cooler than without the fans. Normally warm but pertty cool now. Good quality great price, I can definitely recommend it after you get past the power supply misunderstanding.

Works well and looks like it is built well but the fans are noisy. Thankfully my WD Black 8tb external is only on when I backup files. I would not use it for always on drives as it is noisy. But it does work, in the lowest speed it drops temp from 55-60 C to 35-40 C.

These are really nicely built cooling fans and at a very good price point. They put out a lot of air. They are very noisy even at slow speed. It would be better if there was a super quiet speed setting on the remote. I use this under my Large Router on 24 hours a day hosting many connections, and it is a little loud. The fan I replaced this with was (almost silent), at high speed this fan is really loud. However, it is a well made product that will do an excellent job cooling components.

I'll start with the bad, because no matter what when this fan goes I won't be buying this as a replacement, even if it lasts me for years. Unless it starts going for about $10 because that's the max I'd pay for another one. The "removable" feet. Poorly made. The whole foot setup is just a jerry-rigged setup of a long screw, a hollow piece of rubber, a nut, and a circle of adhesive foam. It's a really long screw that goes through a hollow rubber foot. The way it screws in is with a small nut. That nut is only held in place by a basic adhesive that also holds the foam pad to the bottom of the rubber foot. If that nut detaches from the foam (and it will) then it's basically impossible to put the foot back on properly because nothing will hold the nut in place to stop it from spinning when turning the screw. Once the foot is detached you realize that the screw setup was also being used to hold together the plastic guard/framework holding the whole thing together. So now you have four loose/floppy corners, but it's still held together, mostly, because there are four screws inbetween the 2 fans that ultimately keep the plastic anchored. And you can't just reuse the screws with the nut to tighten the corners down because the screws stick out as far as the feet did (because of how they originally had to screw into the nut, reaching to the far end of the feet) so even just using the nut to secure the screw and clamp down the plastic, the fans will still be elevated on the ends of the screws which defeats the purpose of even taking the feet off in the first place. --------------------------- As for the good... so far it's otherwise about what you'd expect for this price. The fans work. The noise is there but not egregious. If you have anything else making noise or you use headphones a lot you won't notice the sound. As for how long this will last... I only just got it today and tested it, but given the "craftmanship" of the rest of the product I have my doubts as to how durable the fans will be in the long run. I bought this for a dual purpose. My parents like to keep the house warmer than I'd like, in general, and my bedroom being on the 2nd floor and having a gaming PC and 2 TVs and me preferring to have my door shut my room can get quite warm in the summer. So on days when they feel it's cool enough to have the windows open I wanted something I could put in the window to help circulate air in/out faster, and on days when they'll turn the air on I could put it over the floor vent for when the house fans weren't currently running between cooling cycles to keep pulling up cooler air from the basement. Ultimately... once it's set up it seems to work for it's intended purpose, and that's the only reason I'm going neutral on the overall rating with a 3/5. But I probably could've just rigged something up myself with old PC fans for much less but I was hoping I'd be getting a more solid setup by buying this.

Had an issue and seller resolved. Unit works well

Very nice cooling fan it has 3 speed low, mid & high + ON/OFF button as described. The cooling fan is working and high quality product. I will buy it again. I recommend to buy this item.

Exelente para aparatos como consolas o en mi caso compre 3 para mantener frio mi receptor, pues a pesar de tener 4 en el anterior se quemo, al parecer por defecto de fábrica, lo recomiendo y mas si le pones un apagador inteligente

I thought this was a great purchase for the price, and the product description said it was good to use as a window fan. It fit perfectly in my window sill and provided some sufficient ventilation for my work space. It worked great for a few months, then one day while i was washing dishes I heard a 'pop' sound. I thought it was maybe the dishes settling in the rack.. but a few moments later, I turned around and saw FLAMES half way up the drapes in the window that this fan was located. Black SOOT SMOKE everywhere. I scrambled to put out the fire with the nearest blanket. All my technology was on the desk directly below that window, and the window glass was starting to 'pop'/crack and break. Had I not done that, the fire would have engulfed the entire room/apartment! I ended up with 2nd degree burns treated at the hospital. I had to pay to replace the entire window - you could see the worst/deepest burn in the window sill where this fan had been sitting. It had melted right through the metal bottom casing into the wood. 2 laptops and 2 cell phones damaged. Thank god my printer was just out of reach. Thank god I was right there to put it out asap - had I not been in the room, say in my bedroom instead, I'm not sure that we would have gotten out of there alive. My daughter and I had nightmares about it for the next couple of weeks. I had burns on both my hands and legs. My landlord said this fan is likely not CSA approved, so I have no recourse to holding them accountable and making them pay for damages. I will have to look into that. But in the mean time - BEWARE! I didn't take pictures of the window/area, but i still have the melted fan in a plastic bag. I have pics of the burns on my one hand, so that's all I could upload at this point.

There well built not loud and cool my Receiver efficiently. I have 5 fans this size ontop for easy heat dispersing and I would rather have a few fans on my Receiver instead of a warranty denied and get a huge repair bill. Bad enough that I found out the place I bought it from requires warranty repurchase after any fix even if it's a factory defect!!!💯🤬 Fans have good speed a light up switch and I just use my remote power supply plug-ins to turn fans off and on. 👍🏻

Bought 3 of these to keep some networking equipment cool in a closed cabinet. The ambient air temperature is being kept at a manageable spot. My only complaint is that these are pretty loud fans. They've created a constant buzzing in my small office that I get to listen to all day. Once these fans die, I'll likely use the power cables and bracket, and swap out for better quality fans that will hopefully be much quieter.
