AC Infinity MULTIFAN S3, Quiet 120mm USB Fan, UL-Certified for Receiver DVR Playstation Xbox Computer Cabinet Cooling

great, installed in a PC cabinet. works perfectly

Brand name with great selection. Became a fan

Excellent, they do what they are supposed to do at keeping the temperature inside the pc unit cool. Running 6 small internal fans.

I bought 2 S3 fans and installed on my routers. They are very quiet, even at the highest speed settings. Both routers are now cool to touch.

It’s perfect, and has rubber stand , really i love it

very good compact and quite

Amazing quality, nil noise , very effective

As described. Very good.

Note: Product purchased directly from seller AC Affinity and fulfilled by Amazon. I use this to improve the air circulation on my Xbox One, which is housed in a narrow TV cabinet. Even though the cabinet is not fully closed, the external of the Xbox can get very hot, especially during a long session. I placed this fan directly on over the Xbox's top vents, blowing away from the xbox. The build quality is solid. You can shake it about, try to bend or squeeze it, there is no rattling or even creaking noise. Around the frame, all surfaces that you can touch, it is all smooth, no hint of any sharp edges. When the fan is running it is very quiet. There is a mechanical switch built into the USB cable. This switch has 4 positions; OFF, speed 1, 2 and 3. At speed 1, you wont even know it is running. Speed 2, in a room without any other sound you can almost hear it, but it is still quieter than my external Western Digital hard drive. Speed 3, well, you can definitely hear it. Not that the motor is noisy, just the wind noise it generated, and if you have the TV speaker on, it will drown out the noise from the fan. The OFF position is very useful, because I connected to the XBox usb port, and the port is always powered, even when Xbox is in standby/sleep mode. With the OFF position I can switch off the fan when I not using the Xbox. This is so effective, speed 1 is enough to keep the Xbox cool. The fan comes with 4 rubber feet attached, it does a very good job of keeping the fan on top of the xbox. At £15, this us not the cheapest 120mm fan on Amazon, but I am convinced this is worth its price tag. It is certainly has done what I needed it to do and quality is great. Only question is, how long will it last, time will tell. I would highly recommend this fan to anyone looking to improve air circulation for AV devices.

Excellent performance just love it build quality excellent keeps my PS4 and Xbox one x in ample temperature

Update 3/2018: Expansion of the home network to include a home office resulted in another cooling fan for my crowded computer center (converted credenza, snug). The newest AC Infinity now has a variable speed switch, and costs less. Cabinet temps seldom exceed 5-7 degrees over the ambient room temp. The 120mm seems to be the best fan for the money. Original review: Small, but not so small that it can't move air. QUIET! Effective Once "installed" (more like placed in a cabinet), they are set-and-forget. I purchased 2 of these, being unsure att eh time how effective they would be in a renovated office credenza-become-computer center. Within the top half of this cabinet space, just under 3 cubic feet (9"h x 18"d x30" w) I have a satellite modem (runs very warm), 2 routers and a switch, and a desktop refurbished as a firewall. Before stuffing all these components into this space, they occupied the lower half of a bookcase that sat atop the credenza, and all were clearly producing heat. Therefore the notion that these AC Infinity fans (or similar) would be required inside the smaller credenza space. I started by placing one fan in the rear of the cabinet to push air (cool air from below) across the very warm sat modem and router out to the front of the open cabinet, and there I placed fan #2 to help pull warm air out and into the room. Both fans run exceptionally quiet, and I needed to check occasionally to reassure myself they were still spinning. There is a subtle movement of air as well, not a breeze; simply lick the back of your hand and hold it 2 feet away and you will notice the cooling effect on your skin (an old IT "procedure" for detecting failed equipment fans, always works if not sometimes salty). An indoor/outdoor thermometer served as a great way to measure temps outside the credenza and deep inside (placing the remote temp sensor near to the warmest component, the sat modem in my case). For 2 days the interior cabinet temps remained within 6-9 degrees of the room temp. So I removed fan # 2 (front of the cab opening), all without more than 1 degree increase resulting. Bottom line: small but moves air (don't expect a whirlwind or obvious breeze, it's pretty subtle), and very quiet. The rubber feet on all corners eliminate any vibration noises or humming, and also keeps the fan from moving anywhere. The alternative might be the AI-MPF80A2 dual 80mm fans (52cfm total) if space is an issue. If heat is more of an issue than what I described here, consider the AI-MPF120A2 dual 120mm fans, 104cfm total. Depending on how my single 120mm handles heat this coming summer, I may opt for this dual 120mm fan setup. As for the optional fan thermostat and speed control, I simply let my fans run off any available USB port and do their work. Recommended, keeping your gear cool (or not hot) at this price is great insurance.

This is my 2nd time getting from AC Infiniity. My first, two fans affixed to my home server cabinet, have been running 24/7 for the last 4 years. They are still quiet and blowing strongly. That says a lot.

Lo compré para mantener frio un MINI-PC cuando lo tengo trabajando a máximo rendimiento. El ventilador no se escucha nada (tras 3 meses de uso) y mantiene fria la dependencia donde se aloja la RAM y los SSD, al que está destinado el ventilador.
