Vents are on top and bottom.** A: I would actually use 2 fans. One to push and one to pull. I used these for a Dish Network receiver which runs very hot inside the cabinet. I used one fan to blow air into the box and one fan to pull air out of cabinet. Works great. **Q: Can someone out in the community help me!...Excuse my stupidity...there are two usb plug ins..One goes to the wall usb port..how bout the other one?** A: The other port is for daisychaining them together. Like if you have 2 fans and wanted to run both through the same power supply, you'd plug one into the power supply and then the other fan through the second port on the first fan. **Q: I am thinking about buying this to cool off my PS3 original. should I get the single or dual fan?** A: Honestly I think dual fans are overkill. I'm using a single fan in my stereo cabinet with an Onkyo TX-NR737 head unit (125 watts into 7 channels, though I'm only using 3 powered by that amp) plus a Samsung UBD-M8500 Blu-ray and streaming player. That combination is easily putting out at least 500 watts (maybe more) of heat when it's running a good movie ... your PS3 doesn't do more than about 200 watts per Wikipedia. So the fact that one fan running only on medium speed, plus some decent vent holes, takes care of all the heat from my system means no way do you need 2 fans. Just make sure there's some good input/output air holes or grate or something to provide space for the air to flow through your cabinet, and a single fan should more than do the trick. **Q: What is the extension of the usb cord , is it 6ft or** A: It's about three feet, on mine. I have the AC Infinity thermostat, it has it's own power cord to the fans. On my cabinet, I have it powering three fans. It has a big Yamaha receiver and Emotive amp. and it stays nice and cool. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Replacement for an older model AC Infinity fan. Nice new features. *by on Reviewed in the United States June 15, 2016* I have a few of the earlier model of this fan, in 80mm, 120mm, and 140mm.There are some differences between the older model, and the newer model of these fans.- This fan was already assembled. The earlier model, I had to screw the fan guards and feet on.- The older model was only on/off, this new model has the option for Low, Medium, High, and Off.- The older model included a USB-to-AC power adapter. This new model lacks the adapter.So far, this fan is nice, I like the variable speed settings. I like it was ready to go out of the box. I used a USB-to-AC power adapter with this new fan, since the switched item I have it cooling, only has a switched power plug, nothing USB switched. When this 120mm fan was on High speed, it seemed a bit louder than my old model 120mm, but I didn't compare the two too much.I bought this to replace an earlier model of the 140mm AC Infinity fan. I found the 140mm fan to be noticeably louder than the 120mm fan, the older models I own. After that, I decided that when I needed more fans, or needed to replace a fan, I'd buy 120mm, no more 140mm. Well, a 140mm fan began to get noisier and noisier lately, so due to the fan increasing in noise lately, I decided to replace it with this 120mm fan.I was happy with the older model of these fans, though I preferred the 120mm, to the 80mm and 140mm. 120mm had a nice balance for cooling and low noise. So far, I am happy with this newer model fan. The variable speed switch is nice, shame they took out the USB-to-AC power adapter, but that's OK, I still have some from the older model fans, and it's an easy enough item to find and purchase separate.These fans do their job well, cooling the electronics I want them to cool. All of them I have in use, are pulling air through the electronics, though, not pushing it. ### ⭐⭐⭐⭐⭐ AC Infinity AI-MPF120A cooling fan -- Quiet and effective for confined heat-producing electronics -- RECOMMENDED *by on Reviewed in the United States January 29, 2015* 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!EffectiveOnce "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. ### ⭐⭐⭐⭐⭐ Hot Xbox One? No More! *by on Reviewed in the United States March 24, 2016* Xbox One is a fantastic gaming system, but man, does that little black box get hot! Especially after 12-16 hours in Fallout 4. Yes, the XB1 has a large internal fan, but it's lethargic: it draws a small volume of fresh air and pushes out an equally small volume of hot air out the top. Some say this is enough: 'That's way they designed it!' I know, I've read all those articles (and so have you, I'm guessing). But you're reading this review now because, like me, you've come to realize that 'design myth' is just that: a myth. I'm being polite here; you may have another word for it. Put simply: That box is too damn hot. And heat is killer for high-end electronics.My solution is simple and relatively inexpensive (especially considering the cost of a new XB1). It's also two-pronged:PART ONE: This fan. Place it on top of the exhaust vent to help pull hot air up and out. (Use a deflector to redirect air flow if your XB1 is in a cramped location like a bookcase.) Fan can use one of the two USB slots on back of XB1.PART TWO: (and this is important) A side vent fan of some sort. Blowing in. Another 120mm sitting on the outside? Maybe. It's so quiet, I may try that. The fan I chose however was the DOBE integrated side-vent fan. Available on Amazon. (There are several fans of identical design which makes me think there's one manufacturer and many distributors - I chose DOBE because their ad was almost in English). Snap out the old vent/dust cover (use a thin butter knife and throw out the plastic pry included) and then snap in the fan unit. It's a good fit and utilizes the side USB port (I didn't even know it was there). The design gives you back two USB ports to compensate but I haven't tried them (I've read there may be data transfer issues vis-Γ -vis external HDDs but that's beyond the cooling focus here).The two fan approach works quite nicely for me: At the end of a 12-hour Fallout 4 session recently, I lifted the top fan off and put my hand right on the exhaust vent and could barely discern the heat. What a difference!DOWNSIDE? Only from the integrated side-vent fan: A slight fan-hum is audibly discernable even on the low setting. I think I can live with it though given the results. The AC Infinity fan on the other hand is whisper quiet. When the DOBE stops working I may just buy a second 120mm and stick it along the side vent and see how that works. Hope that helps all you XB1 gamers out there have a cool summer! ## Frequently Bought Together - AC Infinity MULTIFAN S3, Quiet 120mm USB Fan, UL-Certified for Receiver DVR PlayStation Xbox Computer Cabinet Cooling - AC Infinity MULTIFAN S7, Quiet Dual 120mm USB Fan, UL-Certified for Receiver DVR PlayStation Xbox Computer Cabinet Cooling - AC Infinity Turbo Fan Power Adapter, for MULTIFAN Series USB Fans --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.de/products/1176317-ac-infinity-multifan-s3-quiet-120mm-usb-fan-ul-certified](https://www.desertcart.de/products/1176317-ac-infinity-multifan-s3-quiet-120mm-usb-fan-ul-certified) --- *Product available on Desertcart Germany* *Store origin: DE* *Last updated: 2026-07-28*
