AC Infinity MULTIFAN S5 Quiet 2 Pack 80mm USB Fan Cooling Fan UL Listed Receiver DVR PlayStation PC Cabinet Cooling Dual Version

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。

数年利用していますが、異音等もなく利用中です。 L2スイッチの冷却やルーターの冷却用で利用しています。

多肉植物用のミニ温室内で送風に使用しています。 ハンディ扇風機などを使用していましたが、こちらの方が耐久性も上でしょうし、配置も自由に調整できるので良かったです。 何よりちょうどいい優しい風と、静音性が素晴らしいです。

2台ある小型水槽のファンとして購入。 水槽用ファンのうるささと値段の高さを考えると、かなり静かでお値打ち。日常生活をしていると付けているのを忘れるくらい静か。思ったより風量が優しい。

Very quiet, good deal for about 1000 yen. Cooling my amp nicely by pushing air in and pulling air out.

よく冷える 音は静か（今まで扇風機）夏が楽しみ 対戦会などで本体持ち込んだ時も使える コスパ良い もう2セット買っても問題ない（モニター裏の熱だまりなどや 予備など） 本体USB電源なんで自動ON OFF 状況次第で風量調整可能 耐久性はわかりませんが 1年なら まあ妥当 2年持てば大満足と思ってます 直で冷やすんで 扇風機なんて目じゃないっすｗ

車中泊用にマット取付けで窓にはめ込み、暑い夜での空気入替えに重宝しています。調理での換気扇代わりには、ややパワー不足ですが車内温度上昇の軽減に役立っています。

エアープランツの送風に使用しています。音が静かで弱でも十分な風量だと思います。防振ゴムが両面4箇所、合計8箇所付いていますので安心して使えます。

perfette! molto silenziose ed utilissime per raffreddare pc, laptop ed altre superfici che scaldano molto. le tre velocita' sono un must! superconsigliato

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

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.
