Highlights –-Easy & straightforward installation, plenty of hardware-Low noise-Great performancePro’s –-Quiet operation-Easy installation, just a screwdriver!-Fan control is smooth & stepless, allowing for fine-tuning of airflow-High quality materials-Fan guards help prevent injury-Fan bearings are very goodCon’s –-Excess wiring length for my application, but not being a specific kit for a network cabinet, I can easily disregard that-Screws provided were either ‘just’ long enough, or way too long. Making the included screws 2mm longer would’ve been greatOverall:These AC Infinity fans were a fantastic addition to my network cabinet. With an easy install and simple wiring, I had plenty of airflow throughout my cabinet with no noticeable noise. The speed dial allows for some handy fine-tuning, and I’m overall impressed with the quality of this fan kit. Any wall-mount network cabinet with twin 120mm fan mounts on the top will greatly benefit from these!

I have an old house with a fireplace from the 1940's with a heatilator system which is great but needs a little forced air to really amp up the heat output. I had great success with similar fans and wanted to do the same for my son's very similar fireplace. This is perfect, single control, low cost, variable speed 115VAC powered. Used on the lower cool air intakes of the fireplace, this unit never sees high temperatures and they work great!

I have a $14 AC Infinity USB fan running on a shelf non-stop for two years. It's inaudible, and works perfectly to expel heat from the back of my NAS. I live in the desert and bought it as a precaution. It's the same dimensions as the fans in this kit and puts out 52 cfm.Each fan in this 2 fan kit puts out 69 cfm. It's packaged wonderfully, includes great directions, and everything I needed to mount them (brackets too) at the top of my bedroom doorway, on either side. The kit is so well done that I was able to repackage everything almost exactly as it arrived. I'm feeling somewhat guilty for returning it.The idea was to circulate cold air from my new bedroom AC unit to the living room (when it hits 100° to 120° here), to supplement the living room AC, "room to room" as the listing says (although they specify heat). I'm afraid they turned out to be woefully inadequate for that purpose, but they might indeed work well for yours. I bought a Dreo fan emitting 1040 cfm.

I put these in the door of my networking cabinet that is installed in my garage. It houses all of my CAT5e for phone, CAT6A for data, and RG6 for tv. Along with my cable modem, Unifi router, and unifi 16 port switch. I used a push-pull setup, pulling fresh air in from the bottom and pushing exhaust from the top to get a nice air flow through. I also have a YoLink smart temp sensor in the cabinet to alert me of high temps. I saw an immediate drop in temp from 102+ degrees to ~86. I added some nice filters to it as well. The only thing I wish this had was a thermostat control that you could dial in on and off set points. I have the fans on a smart outlet as well and will be writing some home assistant code to try and link my temp sensor to the outlet for control soon. The fans over all work great and are high quality aluminum frame.

These were purchased to sit in the upper frame for a room arch to help circulate air. We put one on each side of a 7' opening and they work perfectly. Too bad they did not come in White, so I painted them before hanging them up. My only complaint is the mounting bracket versus the wire connector... it creates a 'lean' against the wire so they will never look squared to the archway... We have used these for over 100 hours already and they purr along with no issues. Work on Low, which is near silent, but does not push enough air, and High - too loud, and we leave it near medium high so its not too noisy and pulls the hot air out of the wood stove room. Would Buy Again.
