AC Infinity MULTIFAN S2, Ultra-Quiet 120mm USB Blower Fan w/ Speed Control

12V QUIET!!! Used to move air over trailer refrigerator coils. Paired with the AC Infinity Temperature controller to turn on when the cabinet air space reaches 84F. See photo. NOW the refrigerator coils has air moving over them and the temps inside the refrigerator stay more constant than before. Fluffy version: The Indel 12v refridgerator that came with our travel trailer was not keeping everything cool in a consistant manner. This was due to the heat bearing down on the outside of the trailer and the enclosed cabinet they installed the refridgerator. NO air flow basically. So we drilled a 3" hole and screwed this blower fan to the cabinet wall. Plugged it into the temperature controller that AC Infinity sells and stuck the thermometer in the cabinet cavity. Now when that enclosed airspace reaches 84F, the fan comes on, sucks the air out over the coils and blows it down onto the seat. It is not too hot or loud to sit next to. I LOVE IT. The inside of the fridge is now off by one degree top and bottom and keeps everything cool. No more bad meat. Believe me, when the lunch meat goes above 40F for over 30 minutes, you will get sick when eating it. Problem solved. I might put one in the enclosed cabinet where all the water lines are to push hot air into the space during the winter.

As a gaming enthusiast, I put a lot of time and effort into building a high-performance gaming rig, and I need reliable cooling solutions to protect my investment. AC Infinity's blower fans efficiently remove hot air from my computer's radiator, and their noise control and automation technology ensure the fans operate at the ideal speed to keep my system cool without excessive noise. The quality of their products is outstanding, and their engineering expertise is evident. I also use a AC Infinity Blower to keep an LCD backplate and GPU backplate cool under high GPU loads (leads to high thermal output). My CPU, GPU and LCD backplate temperatures have all remained well within safe limits, thanks to AC Infinity's efficient cooling hardware. I appreciate AC Infinity's commitment to delivering exceptional products and top-notch customer service. They understand the significance of keeping high-end electronics cool and have developed effective, automated, and reliable cooling solutions. My experience with AC Infinity cooling products has been nothing short of impressive. If you're searching for a reliable company to keep your gaming machine cool, AC Infinity should be your top choice. Their dedication to quality, innovation, and customer satisfaction is second to none. As a loyal customer, I will continue to purchase and recommend AC Infinity products to anyone seeking the best in cooling technology. I thank God I found AC Infinity products because the results speak for themselves. No more high thermals, no more noisy fans and no more worry about keeping things in safe thermal zones even under demanding workloads.

I use two of these S2s on top of the One Connect Box for my Samsung TV. The Samsung box is in a media cabinet with good passive airflow but that box gets hot! Setting the speed to LOW or MEDIUM keeps the box much cooler. You can connect these fans together, then then plug them one into the USB port of the Samsung One Connect Box. They will turn on/off with the Samsung box. Play around with speed settings to find the optimal setting, as I believe the fan closest to the USB plug sets the actual speed and the fan furthest away has to be set on HIGH (per the user manual from the AC Infinity Website). Underneath my One Connect Box I have two AC Infinity Multifan S7 and then a Blu-ray player. The second image "Specifications" is confusing so I would ignore that. These are two S3 fans (dimensions 4.7" x 4.7" x 1"), 19dBA combined when set on LOW, 52 CFM EACH when set on HI. These fans ARE LINKED TOGETHER, you can not separate them, which is why they're sold as a Multifan system. If you're looking for separate fans in this size, get two of the S3s. These fans only have one speed controller that sets the speed for both of them. Since I have these wedged between two components and only the rubber feet are providing any extra space, LOW and MEDIUM are the only settings that don't cause a lot of air noise. I'm assuming the fans won't last super long since I'm using them in a way they weren't built for, but they're cheap so meh. This set up keeps my components cool with very little noise! I've had numerous AC Infinity fans over the years, the build quality is so good they last for a very long time. Always at the top of my list when looking for fans.

I'm using this fan in my small Beer fridge on my patio. My inexpensive fridge had no fan for moving the air and with the cheap temp controls would either freeze my beers or keep them too warm. I couldn't get it to stay in the 38 to 40 degree range. The back of the fridge, where the coils were would freeze into a thick sheet of ice, then so would the beer. I've had this running in my fridge now for about 2 weeks and my beer is at a solid 38 degrees! and no ice accumulation. I just hung it from a shelf with a couple of tyraps, ran the cord with speed control out the hinge side of the door and plugged it into a old cell phone charger with an usb port. Not really what it was designed for maybe, but I love it! Displaces only two beers! UPDATE: After running continuously for 4 months, fan impeller started to get a wobble and got very noisy. Now two months later if finally died. Guess it wasn't meant to run 24/7. So it lasted about 6 months. It worked great while it worked. So my decision is ...is it worth $14 for six months? maybe. I'll probably get another one just because its so easy to install. It's prewired so I just have to plug it into a spare usb charger. But I'll keep looking for a more durable solution. UPDATE 2: Did buy another one.Just didn't find anything else I liked. This one came with nice rubber feet and seems to be better built. Its much quieter than my first one even at top speed. Hope it lasts longer than the first one..Stay tuned... UPDATE 3: My second unit has been going strong for 7 months now. 24/7 No noise, I check it every now and then to make sure its still going. Its circulating the air in my mini fridge so the back never ices up and everything stays at a constant 40 degrees. In the past the back would freeze up with thick sheet of ice and cans in the back would freeze. UPDATE 4: 16 months and going strong! This second unit has been running 24 /7 in my beer fridge for 16 months, what can I say more than that! Update 5. 3/14/19.. Second fan still going strong! Not going to go the math for #of months but... Just bought 3 more to put into an enclosed entertainment cabinet that is getting too hot. New fans seem to be same quality as second fan.

These are good but wish they had a higher speed.

I just added this as a second fan in my av cabinet. It plugged into the fan already there both are working silently. They are attached to thermostat set to 80 degrees they most of the time keeping temperatures consistent at the 80 degrees. I would purchase again!

My AV receiver is located on the top shelf of a wooden built-in media cabinet. I have no doors on the cabinet, and any heat emanating from my AV equipment must vent through the front. My receiver sits on the top shelf and has about 4 inches of clearance above the cooling vents. However, heat used to get trapped between the top of the receiver and the top of the cabinet. Not anymore though! I placed a AC Infinity MULTIFAN S2 on top of the receiver vent and it blows all heat out the front of the cabinet. What I like about this fan is (i) it is well made, (ii) it has insulated rubber feet to isolate itself acoustically from the receiver, (iii) it has three fan speeds, (iv) its a blower configuration that blows the air forward vs. upwards, and best of all (v) it is very quiet. In the "Low" setting - which is sufficient for my needs - the fan's noise level is barely a whisper and cannot be heard across the room when all music is off. The fan is powered by USB or optional AC adapter. To mine I added a compatible thermal switch that activates the fan only when heat build-up exceeds a set point set by me. Once the receiver cools down after turning it off, the thermal switch turns the fan off. I highly recommend the fan, AC adapter, and thermal switch - the link for the switch follows: https://www.amazon.com/gp/product/B078PY8L9F/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

**AC Infinity MULTIFAN S2** I placed this fan on top of my Xbox Series S to help with cooling. It's USB A and comes with a power block, a speed controller and rubber feet. I plugged it in to a WiFi outlet so I can turn it on remotely when I start playing, without having to reach behind the console. Installing it was easy, insert the rubber feet, plug it in, and set the speed. It has three speeds The lowest speed is very quiet and you can barely hear it. I use it on the middle speed, you can hear it if you are listening for it but after a few minutes it fades into the background. I'm not really sure if my Xbox needs it or not, but it does get warm, and it's narrow in my entertainment center. This fan blows the air out sideways, I turned it so it blows out the back where there's room for the heat to dissipate. When I'm using the Xbox, the air coming out of the fan is warm, which means it's functioning as expected. Cool is better than hot, I'll take it. So far so good. I would say it's a good value for the money.

10GbpsのLANカードを導入した際に、一緒に導入を決めたシロッコファンです。 LANカードに向けて、直接 風が当たるように向きを調整して取り付けました。 USB-Aから入力電圧を貰って、12Vで稼働しているのですが、三段階にファンの回転数を調整可能で、 たぶん、12V / 5V / 3Vにファンの電圧を変えているのだと思います。 風量もしっかり有って、静音で、PC本体から電源を採るのでエコですし、 コレが在れば、例えば夏場の熱帯魚の水槽や、外付けのHDDや 夏場のワンコルームの冷却など、イロイロ利用出来るんじゃないか？と、思っています。

Excelente produto, resolveu o problema de aquecimento no meu AV Receiver.

Molto buoni

I bought 4 Ac infinity Fans for my receiver and an for another amp. However I only needed two. One for the Receiver and one for the amp, as they draw out the heat more than adequately . I highly recommend these. If you have heat issues or just want to make sure your equipment doesn't overheat. Perfect for Home Theaters.
