I recently purchased the AC Infinity MULTIFAN S4, and I am astounded by the exceptional quality and performance of this fan. I must confess that, given its price range, I had moderate expectations. However, this product completely shattered those expectations by offering a premium experience.Key Highlights:Premium Quality: The build material and finish are impressive, something I did not anticipate at this price point. The build quality is durable and exudes a high-end feel.Quiet Operation: The fan is incredibly quiet, even at higher speeds. If you're looking for a noise-free environment, this fan has got you covered. It's so quiet that I had to double-check to make sure it was running.Efficient Cooling: I purchased this fan to keep my good old 2018 Mac Mini i5 cool, and it does the job remarkably well. The temperature drop is noticeable, and the device runs much smoother than before.If I could give this more than five stars, I absolutely would. Highly recommended for anyone in need of an efficient cooling solution.

Fan is very quiet, had to place my hand in front of it to check if it was running. It appears to be well made and also reasonably priced. I purchased the fan because my AT&T modem/router was over heating and causing intermittent service. It was either running my A/C at 75 degrees or buying the fan. Saved money buying the fan.So far, it is running well and keeping the modem/router cool keeping my internet service running smoothly.Word of advice: If you are experiencing intermittent internet service it maybe your modem/router is over heating. I found out this on my own after 4 visits from the AT&T technician. They couldn’t figure out why it was happening. Fortunately, I kept a log when the internet was going out and reconnecting. As the temp got over 77 degrees during the day the internet would stop working.

Very silent and Low and Med speeds. Good airflow.Very high quality, well made product. Using this for my AVR located inside a narrow cabinet to improve coolng. USB cable is of sufficient length. Cons: The daisy chain USB female receptacle is exposed and sharp and could have caused scratches on my new AVR, so covered it with a piece of tape.

I've now bought a couple of these fans. They have variable speed and are being used to cool some network devices by sucking air over them. Even at the slowest setting they are very effective and are silent. I particularly like the rubber feet supplied which allows the fan to sit noiselessly on a server or to clip on to the edge of a vertical device. Runs on USB output from one of the devices - they can be 'passed through if the port is needed to connect a signal cable. Not sure if you could run the fan AND power a device through the USB port so perhaps only connect self powered USB devices through this cable.
