  • UPDATE: Just Repurchased! Works great, very quiet, no vibration
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. ... show more

  • PRO tips for the PS4 PRO
These fans are great for ensuring circulation, cooling, and minimizing fan noise for your PS4. I’ll list some PRO TIPS below (pun intended). READ BELOW FOR THE TIPS. Though it’s completely normal for your PS4 to get medium-hot, it never hurts to maximize cooling for any electronic... ESPECIALLY in enclosed places. When the system is cooler, the internal fan don’t need to work as hard, maximizing efficiency and naturally prolonging the life expectancy and overall reducing its noise. These fans are super quiet and by keeping the system cool, the internal fans don’t need to work half as hard, thus reducing overall noise significantly... Which is a great bonus. With these fans on high setting, placed like in my photos, my PS4 never exceeds a mild warmth. These fans are versatile, allowing you to link more fans if you’d like, and allowing you to set them up however you’d like depending on your setting. NOW FOR THE TIPS: 1. Do this first! You’re probably aiming to reduce noise and/or keep the system as cool as possible, so I’d HIGHLY recommend to begin by dusting out the internal fan just for the added benefit. It’s very simple with the PS4 PRO. Simply pop off the top cover and air dust or lightly wipe off the fans and place the cover back in. (Refer to how-to videos online). This’ll keep the internal fans running efficiently. 2. USB tips: (1). There is a hidden USB port in the BACK of the PS4 PRO use that one to keep it out of the way and to leave your front two USB ports free. (It can turn on and off with your PS4) (2). You’re likely using a 4K TV or any TV with many ports these days, so chances are you have a USB port in the back of your TV, that is another convienent option for you. I use this option. (It can turn on and off with your TV) (3). You can simply use an adapter to plug into the wall, but you’ll have to remember to turn it off and on manually. 3. Fan placements: (The side that blows out is the side where the wire is visible) The placements I personally recommend and use myself (pictured) is one fan on the bottom holding up the PS4, blowing UP onto the bottom of the PS4 and one fan sitting on top blowing DOWN onto the PS4. Creating an external fan sandwich. Having the PS4 lifted will also allow the bottom to get some proper air flow. (I found a foam and plastic piece that I placed under the front of the PS4 as well, just to make sure the PS4 sits comfortably & with better balance.. I’d recommend something like that too). Side note: if you’re gonna set it up like this, put something under the feet of the fans if you’re placing it on wood.. Otherwise, it could leave light rings in the wood from the pressure. Alternative placements: (1). You can sit up one of the fans so it blows right into the vents on the right side of the PS4, this’ll help get cold air into your PS4. Not a bad option. (2). You can also sit up a fan at the back of the PS4 (where air escapes from the system), blowing air AWAY from the PS4 - helping suck the air out. But honestly, i think the other methods are more effective. I’d probably only recommend this one if your PS4 is in an enclosed area and you want to help the hot air escape from the area (like fan cutouts at the back of your enclosed area). Otherwise, the other methods work better in my experience. If you found this review helpful, please thumbs up this review! Thank you. ... show more

  • High quality, moves lots of air - save your electronics.
This fan was pretty much what the doctor ordered for my Pioneer Elite SC25. After 6 years of ownership it had developed a shutting on and off issue which was intermittent but the last year the issue really worsenned and would not stay on for longer than 30 minutes or so. I was hunting for a replacement but finding the feature set of that receiver with a class D amp is merely impossible under 3k these days. I use this amp for 2.1 channel sound at high volumes. I bought this multifan S7 from AC Infinity as a last effort to salvage it (amazing sound) and save me some coin and the S7 does the job. I have placed one fan blowing in and one out and it keeps the receiver way cooler. No shutting down issues after about 5 hours of testing with up to 2 continuous hours of use. Needless to say I am very happy and richer as I was willing to spend a large amount of cash to replicate the sound of the sc25. Definitely give this a try if you have cooling needs. Also use it even if you don't becuase it is a preventive measure to cooking your electronics (as i likely did) prematurely and potentially shortening its life. The design of these things by the way is solid, nothing cheap here. Fan is way quiet and throws a lot of air. It is also efficient, the speed selector works well (and makes a difference) and gets powered by the USB plug on the receiver itself which is always powered! Sweet action! Give it a go! ... show more
