AC InfinityAXIAL 1225, Quiet Muffin Fan, 120V AC 120mm x 25mm Low Speed, UL-Certified for DIY Cooling Ventilation Exhaust Projects

I bought two of the low-speed fans to help vent a closet that was getting musty. I put them on a timer switch and I was impressed by the quietness of the fans and also the heavy aluminum construction of the casings on the fans. It is certainly a pleasure to see that there are manufactures who can produce good quality products. Hopefully the bearings will last as advertised because I very much like the construction.

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.

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.

The media could not be loaded.  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.
