AC Infinity MULTIFAN 4, Quiet 140mm USB Fan for Receiver DVR Playstation Xbox Computer Cabinet Cooling

Good quality 👌

静音タイプの冷却ファンで、スライドスイッチによる弱中強3段階の運転モードが選択でき、ファン同士の連動運転も可能となっている 前々からPCの冷却手段に導入しており、優秀なファンというのは既に実証済み。今回は、自分でレストアしたDENONのプリアンプの延命処置として予備機1台を使用したが、電源トランスの排熱量が予想を超え、1台では明らかに能力不足だった為直ぐに2台目を購入。 ファン側での連動運転はせず、プリアンプ側の電源で同時運転させているが、2台動かしていても中運転までなら全く気にならないし、電源トランスの排熱も良好。シンプルながら信頼性の高い冷却ファンだと改めて実感。 ゲームハード等の冷却にも大変オススメ！

Very silent and Low and Med speeds. Good airflow. Very high quality, well made product. Using this for my AVR located inside a narrow cabinet to improve coolng. USB cable is of sufficient length. Cons: The daisy chain USB female receptacle is exposed and sharp and could have caused scratches on my new AVR, so covered it with a piece of tape.

I recently purchased the AC Infinity MULTIFAN S4 to cool my NAS cupboard and it's been a great addition to my setup. The fan is very quiet, even on the highest setting, and provides excellent airflow to keep my equipment cool. The compact size makes it easy to install in tight spaces, I have it attached to the ceiling. Overall, I'm very happy with my purchase of the AC Infinity MULTIFAN S4 and would highly recommend it to anyone looking for a high-quality and quiet fan for their cooling needs.

bought is companies stuff as it is designed for high end consumers. not us regular , rather the breaking bad type of high end consumers. hope you understand the analogy. so what is great. its quiet and high quality it will continue working without supervision especially if you are locked in or doing time. it will continue to work flawlessly behind your back and you don't have to worry about it. its silent and yes there is going to be some wind noise however there isn't going to be any whining noise. I use it to cool tp link deco be85 mesh wifi. the be 85 has inbuilt fans.however those fans were no good . I has to install this unit beneath each of those satellites . now never have had any reason to restart the mesh network. the medium speed is good in summer and I guess I can switch to low speed in winter to keep everything going. I the went ahead and bought the 2 fan version from same company to place under my virgin media hub 5 or 6 and the other end behind my tv ports unit. have had them for a months and I can say this unit is good quality. the power is supplied by usb a type plug which is connected to some usb a outlet on the powerstrips I have near appliances. the airflow is restricted unless you place something under the fan to raise it above around 1 inch above its plastic pucks to achieve silence and better airflow. it can not work with the plastic pucks alone. they will not let enough air flow beneath the fan to throw upwards. it needs clearance on at least the input side of 1 to 2 inches to achieve good blowing power. the 140mm size is good for be85 as it blows inside and around the body of the unit and man oh man is the tp link deco be85 big. so you can get an idea. it is as large as a 70kg persons thigh . so you get an idea that 140mm is a bit larger then a persons thigh . power consumption is ok however I didn't test it. seems the 2 fan 120 mm works as good as the 140mm single fan version. I would have preferred the 140mm version as it was single unit in comparison to the dual 120mm versions which I now have to place 1 below and 1 on top of the other be85 deco unit. definitely buy other stuff from this company . if you need an exhaust fan this is the company. if you need electronic cooling fan this is that company. they have a huge variety of stuff that carters to that class of people who we all hate however they are the ones making all the money after other bad businesses in the world. the 4 or 6 greatest money makers businesses right now running the world . and yes it definitely isn't owing a pizza chain or a restaurant or clothing store.
