Like a lot of other people who bought this, I put this on the end of an Xbox Series X to help keep it cooled better. Mine is inside a somewhat enclosed space and this helps push the hot air out so it doesn't build up around the unit.Super quiet operation too, which is always a plus.

I've got a few fans from AC Infinity, using them to cool different components in different ways. The switch on top of my toolbox in in my garage in central FL (it gets hot in there...) this blower style fan was the PERFECT solution for both of my switches.The 16 port Dell was warm to the touch, now it's almost cool on the top.Top notch quality, great design, better than expected performance.

Amazing performance bought two units to cool a receiver (Denon AVR-S970H) in tight cabinet with no real room for airflow (1/2-1 around edges) initially installed just one for testing and instead of it being 90F degrees its now consistently 75F!!

Although quiet, Its air volume and the speed of moving air is-less-than a pc fan. The high-price tag- is-not -matching-for-low-performance.

I have a Ubiquiti Switch that had constant issues with high temperatures, unfortunately with this model. The internal fan doesn't turn on well into the 70's and 80's. Most the time this device would go between 63-68 degrees. With this small fan though it's dropping it up to 20 degrees and doesn't even go into 50 now. Highly recommended!

As a gaming enthusiast, I put a lot of time and effort into building a high-performance gaming rig, and I need reliable cooling solutions to protect my investment.AC Infinity's blower fans efficiently remove hot air from my computer's radiator, and their noise control and automation technology ensure the fans operate at the ideal speed to keep my system cool without excessive noise. The quality of their products is outstanding, and their engineering expertise is evident. I also use a AC Infinity Blower to keep an LCD backplate and GPU backplate cool under high GPU loads (leads to high thermal output). My CPU, GPU and LCD backplate temperatures have all remained well within safe limits, thanks to AC Infinity's efficient cooling hardware.I appreciate AC Infinity's commitment to delivering exceptional products and top-notch customer service. They understand the significance of keeping high-end electronics cool and have developed effective, automated, and reliable cooling solutions. My experience with AC Infinity cooling products has been nothing short of impressive.If you're searching for a reliable company to keep your gaming machine cool, AC Infinity should be your top choice. Their dedication to quality, innovation, and customer satisfaction is second to none. As a loyal customer, I will continue to purchase and recommend AC Infinity products to anyone seeking the best in cooling technology.I thank God I found AC Infinity products because the results speak for themselves. No more high thermals, no more noisy fans and no more worry about keeping things in safe thermal zones even under demanding workloads.

Got this as a window fan for my jeep. Quiet and I was able to sleep all night!

I placed this on top of my router and dropped the temp from 65C to 55C. It is sitting in a cabinet with a open back but closed front, yet I can still hear it at its lowest setting from a couple feet away. It is quiet, just not super quiet. The cord is also a bit unruly with its length and the extra USB connection; all of that is useful, just in my case it gets in the way and I cannot easily replace it with a short cord.Overall a good product.

Not a lot of vibration. Has rubber feet.Don't use where there is a lot of dust. It builds up in the centrifugal fan blades, hard to clean.

No noise at all, rubber boots are a nice touch. The fan speed controller is awesome. Fair price, cannot go wrong.
