AC InfinityAXIAL LS1238, Quiet Muffin Fan, 120V AC 120mm x 38mm Low Speed, UL-Certified for DIY Cooling Ventilation Exhaust Projects

This fan was packed with a foam insert so that nothing moved or could get damaged. The manual was packed in a separate vinyl sleeve as were the fan grills and mounting screw. Nice job!The AC plug gave me a little resistance but once I pressed hard enough, it went right on. I plugged it in and the fan immediately turned on and blew air but very quietly.I needed a quiet fan to take away the soldering fumes when I work on small electronics at my desk. It's quiet enough so it doesn't disturb my wife while she's working in the same office and has no problem taking the soldering fumes away.

I bought two of these and wired them into a soda machine to replace two broken evap fans. These fans out performed the factory fans that came with the machine. They were smaller and less noisy. The machine ran so much cooler with these installed and were a whole lot cheaper than the factory fans. Would buy these again if needed.

This is a quality metal fan that lives to its noise specification. While I cannot confirm that it's exactly 32 dB, I can say it's really silent and it takes effort to hear it.Fan is made almost completely of aluminium and gives a really solid feeling. Once you mount it, it goes nowhere. I love the way it connects to the power cable as it allows for easy mounting with cable detached and then you can plug in cable even blindly.The only issue I have with this fan is its mounting method. It has just simple holes you can pass the included M4 screws through. I find this mounting method rather unclean and I prefer directly interfacing a good machine screw. Fortunately, it's easy to convert 4 mm hole into #10 machine screw thread. The only thing you need is #10 tap. It works like a treat.

Attached this fan to my diode laser enclosure. It's very quiet but not enough flow to extract the fumes quickly.

This is a replacement for an operating fan in my 12VDC - 120AC 4k Watt inverter that was terribly noisy.Item arrived well packaged with all necessary mounting hardware. Standard two-prong AC outlet cable provided, although direct wiring for my needs was easy.CFM is more than adequate for my system. IR temperature readings show air circulation is doing the job. Fan is very, very quiet, which was the entire reason for the swap. It makes all the difference in the world.

I can't really quantify how quiet it is, but it was quiet enough for my application. I bought it for the 120V, the published longevity, and the airflow. I did buy 2 because I wasn't sure how well it would work for me and as it turned out, I only needed one. I kept the 2nd fan just in case it is needed, or possibly for another applicaiton. Seems to be well made and has been running well for several months now.

I've purchased two of these. A couple years ago I bought one to cool down my mother's old Harman-Kardon AV receiver (placed horizontally on the top panel).Recently the built-in fan of an old rack mounted power amp of mine stopped working. The amp's heat protection was turning it off and on as it was overheating. I placed the LS12038 standing vertically in front of the amp's vent slots to pull air through the amp; no more overheating.

So yeah this fan seems to be of high quality construction and moves a decent amount of air. I wanted to have a fan to get some air flow around my router, fiber modem, NAS enclosure, etc. as even though everything sits on a shelf, the lack of airflow sees everything just kind of stewing. Everything is way cooler now so the fan does the trick.My only beef (which there is a solution for) is the act of moving air does inherently generate noise. When things are really quiet you can definitely notice the soft hum of the fan going and the amount of air it moves is kind of overkill. The solution then is the potentiometer kit they sell. It's super high quality as well and it appears like it has four positions (off, low, medium and high), but it is really a potentiometer with infinite adjustability from off to full power. I think offering a "kit" with both the controller and fan with some of discount would be awesome. It's a bit of a face palm to buy a ~$15 fan and then have to go back and spend ~$13 so the fan isn't full-tilt all the time.
