The fans work great and are very quiet. Keeps my sound system cool.

very quiet operation. Wish it had a little more fan speed but does what it says it would do very efficiently.

I installed it to cool off our router. Makes a 20 degree difference. Bought a second one for the stereo.

Super quality product that looks like it was always meant to be in your cabinet.

From what I know now after installing this fan, this is a well documented quality appliance. It certainly is quiet and it also moves a lot of air.

Great looks, easy to install, noise is very limited, now its time to see how long will it last...

Quiet in low fan mode and only moderately loud on high. Works well and easy to install with included template.

I'm starting to realize that I do not read the fine print often enough.I didn't know this fan had a speed control until I started writing this review. I like it a lot. I liked it before I could change the speed. Very nice. Pretty quiet.Would be really good for my cat's house. I think I'll buy another.

They are quite, easy to install and keeps very cool. Best USB fans I ever bought. I use them to keep my Xbox and PS5 nice and cool and I bought a single fan that my router sits on top of and it keeps my router very cool

With a toddler in the house I have no other option but to store my consoles in a cabinet which is never optimal during use, but just always left the front door wide open for airflow to work along with the vents cut in the back panel of my cabinet. I never had issues doing this for the past few years with my One X or PS4 Pro, or even my Series X (likely because the top heat dissipation), but that all changed when I put a PS5 in the cabinet. It seems like it builds up much more heat in the top/rear of the cabinet before it can escape. I began looking for cooling options and the AC Infinity assemblies looked like a no brainer. My cabinet has some of the thinner board on back so it was easy enough to use the included stencil and a sharp utility knife to cut out a spot in the very top rear of my cabinet, and instead of screws I used some thin double sided tape. Took no longer than 10 minutes to install. After an evening of use I found that the lowest setting was able to move enough air to keep my cabinet at ambient temperature with the front door open while playing the PS5, so I consider this problem solved. On the two lowest settings the fans are barely audible unless you're listening for them or are super close. The highest setting can only be heard slightly over the fan on the PS5. I am more than happy with my purchase and the performance of this unit.

Very quiet.

Tiene velocidad variable , bajo ruido.

Worked perfect and fit just how I wanted.

Nice little cooling fans. Fit my application and help keep my under cabinet aquarium equipment cool.

Lasted less than 6 months, Started getting noisy after 3 months; will not buy again.

I use several of these in my AV cabinet to keep air moving around the AVR. Even on the lowest setting they still produce too much noise to be heard. While extra cost I am re-using the frame and replacing the fans with Noctua 120mm 900 RPM fans driven by an AC to 12V 1A PWM adapter. Sure it moves a little less air, but it is dead silent now. AC Infinity needs to look at quieter fans even at a lower speed as many times you just need to move a little air to keep an enclosure at a good temp.

I cut a hole in my entertainment center according to the supplied paper template. Easy peasy. Moves a lot of air. Enough, in fact, I was comfortable removing the direct amp fans. So far, keeps everything in there cool during heavy use.

Needed this to keep an entertainment system cooler inside of a cabinet, it does the trick by moving a lot of air quietly.
