AI-MPF80A2 Quiet Dual 80mm USB Fan for Receiver DVR Playstation Xbox Computer Cabinet Cooling

working well for about 6 months now. very quiet. use it to remove hot air from AV system. only crib is that the wire is kind of thick and long. it may be a blessing for others who need to run the wire longer. I use a dedicated usb power supply (1mA) to power it. dont want to load the USB port of my receiver all the time.

This fan is very good has a good build quality, looks very good and runs very quietly , performance is also good but only negative cost is very high.

I damaged my old AV receiver due to overheating when I started using a new cabinet. After repairing, I started using the receiver along with these fans. Earlier I was skeptical using fans in AVR as they might produce noise, but these fans changed my view. These are very silent. The package does not come up with and power adapter, so you need to either buy some or you may use any old USB mobile charger, preferably with current output rating of 2A. The setup provides an extra USB port to connect more similar fans in series. At low speed it is cooling off my AVR (which is transformer based, so heats up quite an extent) now without any noticeable noise.

Working fine with no noise.

Nice build quality and silent Value for money

Worth for the money spend. Surprised !!! about how much cool the AV receiver (after 3 hours continuous use ) by the silent performance of AC INFINITY Satisfied with the service by the seller (Yuva Fashion Store ) in shipping the product from New York to India

Super quiet, super performance. Barely audible from a couple of feet away, thrse rest nicely on top of your AVR. TheSe belp cool rather quickly. Certainly worthy of a mention for a good buy.

This product does the job well, not much sound when you use Home theater and keeps the devices cool. I use it for my Denon AVR and planning to get another from iBhejo. They have delivered it ahead of delivery time.

I bought these to cool my amplifier down in the summer time. Works perfectly. No wind noise from them at all! And they do a good job. Buy buy buy if you have a over heating problem in your amplifier. The only negative things are that the cord is quite stiff. And long. Otherwise perfect.

My last cable modem up and died after just one year, I'm pretty sure because it got so hot all the time. It was a modem+router so extra hotty-hot-hotness from all the circuitry packed into one case. My son thinks this is sort of normal lifespan for routers and modems - he expects only 3 to 4 years. Well I got 8 years out of one of my last modems and 10 out of the other (same modem, WTGS54 whatever that was, it was a very good modem for its time and I got more than enough throughput from it for my needs, including streaming video, I was still running one up until 2 years ago). So *I* was shocked at its short lifespan (especially given the cost, over $200) even if he wasn't. There is just more electronics involved in these tasks, packed into less space, than the older modems. They are GOING to get hot. So in order to keep that from happening again I bought this USB fan kit, comes with 2 fans hooked together, to replace the floor fan I had aimed at the new modem and separate router. I was getting some of these anyway to put on my LED grow lights to cool them (they will ALSO last longer if you keep them cool) so I took one of those and shoved it under the router (because its a flat design, give me vertical any day) and stood the other one up next to the cable modem (which is vertical). I've got them on low and they are cooling both devices very well. On low the router gets barely slightly warm, and the better design of the vertical case for the modem leaves it totally cooled down with this little fan. If I had it to do over I'd look harder for a vertical router as well, its easier to keep them cool. AND they take up a lot less space! I've got a bunch of old computer cases with fans going to waste, I will likely make some USB fans from all those old bits and pieces, but they are likely to be a lot louder. This fan is extremely quiet even on high. I can't hear it at all on low. Also these fans in particular are optimized for humid environments so I wouldn't use anything else in my grow room. A lot of people use the other dual fan kit with the larger fans but they are using them to move air over microgreens to cut down on mold and fungi, I don't have that problem, I just need to cool the lights to improve their longevity, so I'm trying these smaller fans (take up less headroom over the lights, giving me more space under the lights because I can move them further up). I highly recommend cooling your router/modem/game console whatever electronic devices you have sitting around generating heat with some kind of fan, and these are very quiet, easy to assemble (as in plug them in), and very effective. I've seen some people insist that you shouldn't do this because it might "blow dust into the case" - where do these guys live, in the middle of death valley? LOL! Just do it. I've had a floor fan blowing across my very very ancient laptop to keep it from overheating for about 5 years now (even laptop coolers can't cool it enough) and its still going strong. I can even play (very very old) games on it still. Heat will kill your devices WAY faster than whatever tiny specks of dust these fans probably won't blow into the cases anyway. Also, if you have one of those stupid refrigerator closet things where they've built an enclosure all the way around the fridge, that is trapping heat and shortening the life of your expensive stainless steel fridge - you can use these fans to draw hot air out of that too (though I'd go with the larger version for that). Personally I'd tear that crap out but failing that, install these in a side or back wall and pull that heat out of there. Your fridge will thank you. Your bank balance will be the better for it over the long haul.

Very efficient and quality product

寝室にあるルーターを冷やすのに使っています。 存在を忘れるくらい静かで、私は気になりません。 ルーターもしっかり冷えます。 買って良かったです。

Very happy with my purchase, those fans work great and are easy to clean!
