AC Infinity MULTIFAN S7, Quiet Dual 120mm USB Fan, UL-Certified for Receiver DVR PlayStation Xbox Computer Cabinet Cooling

I buy so many of these fans for different uses I’m tired of writing reviews for them lol! They’re quiet, well powered and work a long time. I typically run them non stop and they hardly break. Verify your size for whatever you’re using. There are a lot of options.

I bought a new stand for my TV, center channel, and receiver. The spot for the A/V receiver got quite warm even with vent holes in the rear. I ordered these dual fans and they're better than I expected. The receiver case is cool to the touch now. Not room temp, but actually cool. For $20, you cannot beat these.

I bought these to create an exhaust out the back of an entertainment stand that has a media server in it. It has been running for over 6 months now without issue.

I'm using these in a makeshift server cabinet that houses a bunch of electronics that like to get hot. They're very quiet, move a lot of air, and feel like quality products. I mounted them on a sheet of ABS plastic as pushers with two 80mm pullers on the other side. Both are connected to the AC Infinity controller which "supercharges" them at max speed. They bring the temp in the cabinet down to 2-3°F above ambient. They provide plenty of cord so it's easy to place them wherever you want and the female usb connector makes it a breeze to daisy chain if you need.

It's a quite unit alright! It only works well when set up right. It doesn't move much air but it does cool my gaming laptop just enough to prevent over heating. I would suggest if you want more air movement don't worry about the noise and get the faster fans. It's a great model I have no problems with it. I have the fans running almost all the time.(because I forget to turn it off but it's silent as far as I'm concerned. But the real issue is just it doesn't move air as fast as the listing says it does. The unit is built tough though and has lasted over 100 hours straight. When it's left on for a long while it will push less and less air over time atleast that's how it feels to me I haven't checked it with a meter though. If you want a durable fan buy from this company just make sure you pick out the right one and don't worry at all about noise all models are very quiet far as I'm concerned! People complain to much about the noise! Also the different speeds don't matter it's better on high barely pushes air on low. Hope this helps someone! ✌🏼❤️💯

2/11/2021 UPDATE! Just reordered another S7 pair of fans! Andy, I have never met you, but I sure like these quiet fans and continue to recommend these!I have three of these fans in a media closet that is about the size of a tall refrigerator. Inside on shelves I have a high-powered AV receiver, a BluRay player, a Cable TV DVR, and other stuff that is producing an amazing amount of heat. When we built the house the wife wanted all AV equipment hidden, and as an Audiophile I wanted to be able to see what I want to see and hear what I want to hear in the Home theater seating area, but without any extraneous noise.Solution: I bought this item, and set two fans on top of the AV Receiver and a third identical fan on top of the cable box/DVR. Closed the door and waited an hour. Heat load dropped in half. I did not want to just move a hot air around in this large closet, so there is a passive vent installed in the sealing of the closet .... just a simple louvered floor vent like people have in their homes for floor heat. I just waited until the wife unit was out of the house and used one of her good steak knives to saw a hole in the drywall ceiling a drop this Lower cheap floor vent in:) Vacuum the mess up and done. These fans have been running flawlessly for two years now - and my wife, who could hear a mouse fart, has never noticed them.Quality/overall impression: Frankly, I thought these were two cheap to be really durable, but I bought them because at the time they were one of the few USB fan setups with a speed controller, no fan-boi disco light show LEDs, and with a CEC rating. The fans are very quiet, well-made, and have nice rubber anti-vibration feet.I was nervous about leaving cheap fans on 24-7 because the last thing I want to do is have a house fire because the units were wired up by orphaned slave labor recruited from a deplorable third world slum. But those fears were immediately put out of mind when I opened the box upon receipt. Beautiful packing, high quality wiring and fan construction.I am back on their site today reordering a second set to place on my desktop next to my computer workstation. I have a couple of good friends who work designing high end consumer electronics - the really pricy stuff. Both techs told me that placing a good quality cooling fan on an AV receiver can add several years working lifetime to such units.Therefore, I highly recommend these AC Infinity products. Just buy the dual fan setup, set the speed controller wherever you are comfortable and forget about them! (slower is a little quieter, but even on high these were very acceptable for my application) And like I said, I am back today repurchasing another set, which I should have done long ago:) Heat kills electronics. And if you are checking out cooling fans, you already know that stereos, AV equipment and computer gear can generate enough heat to slowly nuke your gear...Next possible project for these.... We have a couple of large walk in closets, which we keep the doors closed on because our ever-curious weenie dogs like to curl up in when we are not home. Anyway, I put the old computer fans, which were too noisy, in the closets to keep the air circulating and not smelling musty when we have been gone for awhile. One of these small fans would be much quieter, and would be strong enough to push all the air it needs to under the closet door to keep things smelling fresh in there - even after we have returned from a couple weeks vacation.

I've some other AC Infinity exhaust fans around the house. We use them for laser exhaust, and I use them for soldering/welding exhaust. They're nice fans -- variable speeds and decently quiet. I was hoping for a good set of 120mm fans from them, and I'm not disappointed.Comes with a USB power cord and manual switch controller that controls both fans. Off/low/med/high speeds. Even on high speed, this thing is whisper quiet. Also comes with shock-absorbent pads around the screws on the case corners. Nice for low vibration mounts. Should keep things ultra quiet.I can't speak to the longevity of these, nor can I speak to their stated airflow, as I've no real way to measure it, but it seems like a decent set of fans, and the volume is nicely low for those of us who like some quiet.

This is two USB fans that are attached to each other. There is one inline three speed switch and they are quiet.
