Review on 🌀 AC Infinity MULTIFAN S7-P Dual 120mm AC-Powered Fan with Speed Control – Ultra-Quiet, UL-Certified for Receiver, DVR, Playstation, Xbox & Component Cooling by Brian Barnes

Fantastic, silent, powerful computer fan with AC and USB power supply. I needed something to cool my Blu-ray and old PS3 case a bit and this fits the bill perfectly! NOTES: -3 speed settings. I leave it on L (low) all the time. M and H are great, but I don't need that much power. I bought a version of this multifan that comes with an "overclocked" USB power supply. Causes the fans to run slightly faster than when plugged into a standard USB port. Fuck it, I didn't do it, it's definitely strong enough without it. No matter what speed you choose, it will always be quiet. In the truest sense of the word, it is almost inaudible in the room. The switch controls both fans at the same time. There is no independent control. You can also use the switch to turn off the fans. You can daisy chain multiple USB fans from this brand. This is not necessary, but this kit plugs into the USB socket for another kit. The fan switch control controls ALL fans at the same time. The cable length between the two fans is about 44 inches. The cable length between the fan splitter and the USB power connector is about 6 feet. Rubber legs can be removed if desired. First you need to unscrew the fans and then you can remove the screw from the rubber. Removing the rubber feet will also remove the fan grills. You can remove the fans on either side. If you don't like grills, you can replace them with something else. Standard 120mm lids/grids work great for them. You can reorient the fan power cord to the inlet or outlet side. There is a small groove for this. It is approximately 5 inches wide and 5 inches high. The fan itself is 1 inch thick. but the bars add about half an inch more, and the rubber feet add another half inch. See pictures for more details. These are 120mm thick grill fans. If for some reason you need to rewire them, they are simple two-wire fans with a black (ground) and red (power) wire. They are currently lowering the temperature. from 81-83 degrees in the closet to around 73-75 depending on the day. Room temperature is usually around 73C, so it does a great job of keeping it close to room temperature on low power! UPDATE: So for another application I bought a separate 120mm AC Infinity fan to add. If you plan to chain/chain more fans, the fan/controller with its cables/speed controllers connected to the output (lowest in the chain) will manage ALL subsequent connections. What does that mean? If your first fan is set to medium, all subsequent fans can only go to medium. For me I had to set the first fan to high and then my next to medium for my needs to get the right airflow. A small problem and since we are dealing with USB connections of course you can always just get USB socket adapters to get around this problem. No star deduction as I had a slight feeling this was happening.
