AC Infinity, AXIAL S1238D Muffin Fan, Dual 120mm x 38mm

Excellent quality, high performance fan pack. It move a high violin of air and is extremely quiet. I mounted it above a Mr Heater Blue flame heater in my garage and it does a great job

I purchased two 120mm fans from AC Infinity, one high speed and one low speed. The short story is that both fans are awesome quality. The high speed fan is a little too noisy for a living room entertainment center but makes some impressive airflow. The low speed fan is quiet enough to use in the living room, 6 feet away, and not make a noticeable amount of noise while still moving plenty of air. If you are looking for a fan, buy one of these. I built two stereo cabinets with intake filters and used these fans as exhaust fans. Since I had two cabinets, one for the shop and one for the house, I bought both the high speed and low speed fans figuring I would put the high speed in the garage if it was too noisy for the living room. Both fans are very high quality, sturdy aluminum surrounds. The high speed fan is about twice as thick as the low speed fan but otherwise they are identical. All the hardware necessary to mount them was included and mounting screws were long enough to mount through 3/4 inch thick plywood without problem. The high speed fan did turn out to be more noisy than I wanted for the living room so it ended up in the shop. The primary purpose of the cabinet in the shop was to protect the stereo from metal dust and other nasty garbage, but I have no doubt that a single 120mm high speed fan will circulate more than enough air to cool any electrical component or series of components you could assemble. I am using a standard 16 x 20 inch ventilation duct filter from the hardware store and the fan generates enough force to hold the cabinet door (20 x 24) shut with a clean filter. Even now that the filter is getting clogged with sawdust and grinder dust the fan is still moving air. The only downside is the noise. For comparison, if you have heard a PS4 switch from normal cooling to high speed cooling, that is about how loud this fan is. The low speed fan is perfect for my stereo cabinet in the house. It is quiet enough that you forget it's on as soon as you turn on the radio or TV and sit down on the couch six or so feet away. I have a receiver and a PS4 in the cabinet and the cabinet temperature has not risen above ambient enough that I can tell by feel, even after hours of movies or video games. This is in a small footprint cabinet with no room inside for internal circulation, so the PS4 gets hot very quickly without the fan on. I know the fan is doing all the work cooling and getting it done nicely. I have little doubt these fan will last for years based on the quality and they are definitely worth the price.

Just out of the box, this looks like quite a nice fan. _In_ the box, it looks even nicer - enough so that I found myself wondering how much less I would've paid for just the fan with bare leads. Still, if I'm going to be paying $17 for a fan, the nice packing job, slickly printed manual and black enamel hardware (2x custom-branded finger grills, 4x 55mm M4 screws, 4x thick rubber washers, and... err... 5x nuts. oops. guess there's a spare) do help a little to make it feel like I'm getting my money's worth. The fan itself is much sturdier/heavier than I expected - having apparently missed the bit where it was described as having a cast aluminum frame, I assumed it was the same black plastic as most DC muffin fans. It's not. The frame on this thing is built like a tank, and, while the hub & blades are still the usual PBT plastic, I suspect the short stubby shape will also be less damage-prone. Not that I regularly damage fans by jamming screwdrivers, fingers, or whatever other device and/or appendage might be convenient into the spinning blades - that would be silly. And reckless. And might explain why my fingers are always sore. I'd initially wondered about the effect those short blades with the large hub, and, as expected, it causes a pronounced ring or tube-shaped airflow, with a not entirely dead, but much calmer area in the center. I can imagine some specific cases where this might be less than ideal, but I expect it will make little difference for enclosure cooling (except in my case, where the heatsink placement means it's solidly an advantage). It's not a silent fan by any stretch of the imagination (not surprising, for a ball bearing fan at 3000+rpm), but it's not loud or intrusive. If I set it on my desk, I can hear it from the other end of a silent room, but you won't find yourself yelling over it - I've had PCs that ran much louder. Those vibration dampening rubber washers in the hardware packet will also do a lot to keep it from resonating your enclosure into a loudspeaker, too. As can be seen by the cast-in logo on the frame (or by looking at AC Infinity's site), this is a re-badged Cooltron fan - apparently the FA8025B11T7-96. Searching by model number, you can find datasheets with static pressure & airflow performance graphs, if you're working on the sort of project where that's important or you're the sort of person who can start planning to that sort of detail without immediately getting a headache. I included pictures of the power terminals - with and without the cable attached - as that was something I couldn't find a clear view of before ordering. While the wall end of the power cord has a polarized plug, there isn't any sort of polarity protection on the fan end - it's possible to attach the cord in either of two orientations (which Cooltron's datasheet suggests is perfectly safe), depending on which is a better fit for your project. Also visible in the shot of the terminals is an M4 threaded hole for an optional grounding screw (not included) - there's one on the opposite corner, too. If you make it to the end of the (short) manual, you'll find another unadvertised surprise waiting for you: a two year warranty. Of course, when it dies in a year and a half, I'll have completely forgotten the warranty, toss it in the bin, and go shopping for another... but it's the thought that counts... or at least that's what my mother told me every time I got a gift that I couldn't imagine myself ever using. Longevity remains to be seen, but overall the fan makes a good first impression. Well, mostly. I was disappointed to discover that, contrary to the description, it neither includes, nor makes, nor tastes like muffins, and would be a poor choice for a bake sale.

風の強さは凄いです。 最初は電気ストーブの暖房効果を拡散する目的で ストーブの正面に向かい合うように設置して、 MAXで付けてみて試しに部屋でタバコを吸ってみたら、 煙が真横に流れて行ったんです。ファンの近くじゃなくて、部屋の真ん中とかでも同様で。 普通、上に行く煙が横に進むのは異様な光景で、 ストーブに煙が全部ぶつけられて可哀想でした MAXだと、あまりの風の強さに暖房効果よりも体感温度が下がって寒かった... 風量調節を上手くすると、 電気ストーブでは室内温度の限界が19℃だったのに 23℃まで暖かくなりました！循環って大事！ ストーブの周りだけが暖かくて、足元は寒い現象は解決しました この部屋全体の空気が循環する風量って普通の大きい扇風機とか、エアコンのレベルに匹敵しますよね 乾燥に弱い人には残念ですが 12cmファンでこの風量は本当に凄いです。 巻き込み防止のカバーと、ネジ、防振のゴム(ワッシャーみたいな)、L字のマウントが付いてて付属品も十分ですかね安心感があります 私は全く使ってません 今回は初期不良なのか、 ON、OFF切り替えのカチッという音がせず、 リモコンを回しても反応しない事があります。 こねくり回すと付くので問題ありません 配線も硬くて長くて太くて、取り回しが効きにくい感じです コンセント→リモコン→ファン1→ファン2って順番なんですけど、 ファンからファンの部分の配線が長くて、ファンを隣に並べて使う場合は配線を8回折り、畳んで纏めました。 切って、繋げる。が出来ると綺麗に収まりますけどそのままの使用だと少し利便性が低いと感じる所はあります なので中身や配線も弄れる人なら最強製品かと。 車のエアコンフィルターと、活性炭を使って、タバコ用空気清浄機をDIYするのも良いなって思った。 ストーブと併用した暖房効果も捨てられないし、換気扇としても優秀ですし。パソコンに外付けしても物凄い冷却効果ですし。 どう使ってあげようか迷いながら数ヵ月経ってしまいました... 製品が優秀すぎて、設計図とアイデアがどんどん湧いてきて決定できない あと2つくらい買わないと救われない病気になってしまいました ありがとうございました。

La calidad de este ventilador está perfecta, no hace mucho ruido molesto, todo el marco es de metal por lo que se vuelve pesado. La velocidad del aire también es buena. Lo utilicé para crear un tubo de aire para un limpiador de semillas y funciona perfecto. Si lo compraría otra vez cuando necesite uno nuevo.

Cumple muy bien su función de enfriar una caba de vinos que emprote y a la cual en un inicio le había realizado unos agujeros laterales al mueble para que respirará, pero sentia que se calentaba mucho y de ahí la desición de poner este ventilador el cual mantiene muy fresco el interior del gabinete al estar cambiando constantemente el aire, el enfriador se mantiene fresco. Solo hace un poco mas de ruido de lo que esperaba pero no molesta, pero sabes que esta prendido.

マイナス部分が幅広の為に、安いコンセントでは差さりません。 要注意ですね、

自作の空気清浄機に使用していますが ２４時間運転で抜群の静粛性です
