AC Infinity AXIAL 1225, Quiet Muffin Fan 5", 120V AC 120mm x 25mm

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.

I bought two of these fans to help cool some rack-mounted hardware being used for video. I needed something reliable and quiet, so figured I'd go for something on the higher end. However, regardless of how much they charge for these fans, they could probably charge more. They're worth every penny, and then some. They're barely audible, and I can't hear them at all from a few feet away. (Granted, they have a low CFM, but they're quiet even considering that. I didn't realize before buying them, but their housings are made of metal. Let me say that again: Metal housings. I don't mean the guards for the front and back (though they are a quite solid metal, probably steel), but the body of the fan is metal. They're heavy, and feel very solid. I've installed an uncountable number of computer CPU and case fans, and these are in a different league entirely. The mounting hardware is good quality as well. Despite my best [accidental] efforts, my power driver couldn't strip one of the screw heads. I'm guessing they're reasonably high quality steel, too. It also comes with 4 rubberized vibration-damping washers. The only thing that's a possible negative is that the fans have a metal body but do not have a grounding conductor. If you mount these to a non-grounded chassis, cabinet, or etc. then in a fault state they could be a shock hazard. If this is a concern for you, look for low-voltage DC fans that have good quality power supplies. Despite that, these are definitely worth the price, and I'd buy them again for future projects.

Excellent low noise that solved my problem. Been a “fan” of AC infinity for many years. All of them are still working!

Installed in the back of my entertainment center to keep various electronics cool with the door closed. Some items to note: The holes in the fan body are small - #6 machine screws are the only thing that fits and they will need to be at least 2 1/2" long to hold the grill and fan to a thin wall. The cord plugs on to two metal tabs on the side of the fan and can pull off very easily. Use a wire tie to secure it to the nearest bolt so it won't come free when tugged. This fan is slightly louder than a laptop fan in "high" mode when it steps up due to computer running hot. It was quieter when first installed and got louder after a day of running. It is not very noticable when the tv is on. When everything else is off it can be heard across the living room. Think of a vcr rewinding a tape (if you are old enough for that). It does move a good bit of air. I cut a hole in the back of my cabinet and the fan blows to the front. You can feel air coming out around the door gaps when it is closed. I used to have to keep the door partially open to keep receiver from shutting down due to temp if the Xbox was used. Now everything is cool to the touch even after everything running for a couple of hours. I might put a "filter" on the outside of the fan to keep dust down inside the cabinet and also kill some of the noise. I would buy this again.

I’ve always wanted to be able to close the cabinet doors while using my receiver. This fan allows me to exhaust the heat and bring in cooler air allowing my equipment to run cooler. I chose the quiet model and I can’t hear it with the doors closed. It came with an AC plug which I have connected to the switched outlet on the receiver. The installation steps were straight forward and would have been easier if I had been able to move the 200 pound tall cabinet that I installed it in. The fan case is metal as are the wire screens. Using the screen as a drilling template required no measuring. They recommend a hole size to match the fan case. That is 4.75” for the 4” fan. I was not going to buy a $30 hole saw for this one project so I made the hole 4” (the diameter of the blades) Packaging was excellent and I bought two so I have one for the next cabinet I build.

It has a metal frame. I chose the low-speed model to circulate air and cool an appliance.

This fan produces a good flow of air. After some discussion, we decided to attach this one just above the CPU, on the top of the case. We experimented with it facing in or out, and the best for us is OUT. We also have the side off the case, as we just can't seem to get enough airflow otherwise. We are considering water cooling for next rig, but can't afford it yet. If I put your hand over it, I can feel the heat, so I know it's working. Also, it plugs straight in to the surge protector, so it stays "on" even after the computer (with all the other fans) is turned off. You prolly know this, but CPU's and their heat-dispersing parts can warp if overheated. This leads to more overheating and the potential destruction of the CPU. This fan is an inexpensive yet effective solution to that ever-present issue. I especially love that it continues to dispel heat after the computer is switched off. Well worth the money! I only wish I'd bought it sooner. BTW, this fan is just loud enough to hear it running when the computer is off. It is under the desk, and when the computer is running too, the fan is too quiet to hear over the other six fans that are part of the whole rig (CPU, video card, and 4 in the case). When we first got it, I kept reaching under to feel the airflow to make sure it was still on! 🤔😃 We went from the computer shutting down several times a day from overheating, to it happening maybe once a month. The computer gets heavy usage from online school, graphics-heavy video games, photo and video editing and more for 12 hours + a day. Having to let it cool off so it would restart was a serious inconvenience.

Perfect for use in my 6’x2’ locker cigar humidor. Very quiet and moves air nicely. Would most definitely buy again.

Short story: I was looking for a quiet fan for my FABRIKOR Greenhouse cabinet. I finally decided to get this and I can’t complain. It pretty quiet. I had to buy a speed controller separately. I’m sure this seller has options so you can buy the Dan and the controller together. Anyway, thjs works great. Long story: By mistake, I bought this bigger size when I should have bought the small size for my greenhouse. I bought two different kinds of fans (different sellers). The other two were either too noisy or too big. Overall, they were not suitable for my cabinet. Most importantly, they would lower the temperature in the cabinet below 60° C and lower the humidity level below 55%. So, I didn’t search or buy another fan for 6-7 months until I found this option. The cabinet started to smell a little musty, so I definitely needed something. I am honestly impressed with this product. To me, it’s quiet enough. I’m a light sleeper, I kept this on a lower setting (I bought a speed controller separately) and I barely heard it. I highly recommend this if you need a fan for your cabinet. Side note: the mount you see in the photo is not included. I bought it on Etsy - CADJungle.

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.

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

In this case it is 100% correct they are very good quality, the plug in to the fan is nice and stiff and not half falling off the plug to the fan. Very happy with this and will be getting more 100%, good price and good quality part.

AC100V,1500Wのモータ冷却に使用。今までは30分で高温で停止。このファーン取り付け後、1時間以上連続運転出来る用になった。
