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

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.

New campers have vents in the roof to allow air to come it at the bottom and leave at the top.Natural ventilation.Vintage camper usually have a door vent at the lower end of the refrigerator and a top vented door to attempt a natural circulation.This works some what but not efficiently.Added one of this fans to the inside of the upper door - work good. Added another fan and it is so much cooler around the refrigerator.Very very quietGreat valueThe size was perfect for what I needed.It would be nice if they could be thermostatly controlled as I now need to plug and unplug them.Bought two so that is a good recommendation from me.Comes with all the hardware to install (a bonus).

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.

Bought two of these. Remarkably quiet fans, well built, ball bearing. One is used to provide gentle circulation for plant seedings. The second is used to blow air across a cutting board and away from me when cutting up onions - no more tears!
