I needed something to help cool my blu-ray and old PS3 cabinet a bit, and this fits the bill! NOTES: -3 speed settings. I keep it on L (low) all the time. The M and H are great but I don't need that much power. I bought the version of this multifan that comes with the "overclocked" AC adaptor for the USB plug. Makes the fans run a bit faster than if they were plugged into a standard USB port. Go fig I didn't that, it's definitely powerful enough without that. No matter what speed you choose, it's always whisper quiet. Literally, you can barely hear it across the room. The switch controls both fans at the same time. No independent control. You can also use the switch to turn the fans off. -You can daisy-chain multiple USB fans together from this brand. Don't need to, but this set is wired with a female USB connection for another set. The fan switch control would control ALL fans at the same time. -There is roughly 44 inches cable length between the 2 fans. -There is roughly 6 ft of cable between the splitter for the fans, and the USB power connection. -The rubber feet can be removed if desired. You have to unscrew the fans first, and then you can take the screw out of the rubber. -When you remove the rubber feet, this removes the fan grills as well. You can remove the fans on both sides. If you don't like the grills, you can replace them with something else. Standard 120mm covers/grills work on these just fine. -You can re-orient the fan power cord to the intake or outtake sides. There's a little groove for that. -It's about 5 inches wide by 5 inches tall. The fan itself is 1 in thick. but the grills add about half an inch more, and the rubber feet another half inch. See images for more detail. These are 120mm fans through and through, with a thick grill. -If you need to rewire these for any reason, they are simple two wire fans with a black (ground) and red (power) cord. Currently, these bring my temperatures down from 81-83 degrees in the cabinet to about 73-75, depending on the day. Room temperature is usually around 73, so it does a great job keeping things almost at room temp, just on Low power! UPDATE: So for another application, I bought a seperate 120mm AC Infinity fan to add onto this. If you are planning on linking / daisy chaining more fans, the fan/controller with it's wire/speed control closets to the outlet (lowest in the chain) controls ALL later connections. What does this 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, then my subsequent to Medium for my needs to get the airflow right. Small issue, and of course since it's USB connections you can always just get USB outlet adapters to get around the issue. No star deduction as I had a small feeling that happens. Review: Success! - I bought these fans in order to cool down my media cabinet that has a PS4, Roku, and surge protector; it has 3 shelves. I recently put my PS4 in a cabinet to keep things less cluttered and noticed instantly that the PS4 ran pretty hot, which lead me to leaving the door opened to the cabinet. The issue of overheating is what pushed me to find ways of combating this issue. The install -Everything was very easy! Their wiring took all the guess work out of the install. All you have to do is plug it up to a USB, and yes I recommend using their USB plug, it does make a difference. These are meant to be stood up, but my plans were to mount them. I disassembeled the fans and used the wired vents to trace it out onto the back of my media tower which is made out of that hard cardboard stuff. I used a jigsaw to cut it out and drilled (4) holes for the (4) screws that keep the fan together. Luckily, I had (8) screws that were slightly bigger than the holes in the fan, so I redrilled the holes to fit the new screws. I placed the fans on the backside of my cabinet, while using the wire vent on the inside of the cabinet and used the rubber feet to keep everything together. Surprisingly enough, the unit is tightly fastened to the cabinet with just the screw and rubber feet. I have (1) fan bringing in cold air from the bottom, while (1) fan is sending out the hot air from the top. (In the process of covering a 3rd hole that is used for wires with a circular outlet that has silicone wedges.) I have it hooked to the thermal remote and sensor. I have the thermal sensor behind the internal PS4 fan. Function -Noise: what noise? Even at max, theres minimal noise! Very surprised. I have had no issues since installing, it just works on its own. It pumps in/out so much air! (I have the fan speed to max.) I wouldn't recommend buying fan filters, it will hinder how much air is being pushed. I tested using one, and noticed an 80% reduction (at least)! (It couldve just been the filter). The thermal remote turns on the fans when it hits 88 degrees, and when it goes below 88 degrees, it shuts off. Overall -I am very happy with the product! The value and quality are on point! AC Infinity just made it too easy to use and install their products! The products just work, I have no worries about the performance or longevity of the units. I recommend their products 100%. ## Features - Ultra-quiet UL-certified AC-powered fan designed to cool various electronics and components. - Features a multi-speed controller to set the fan’s speed to optimal noise and airflow levels. - Dual-ball bearings have a lifespan of 67,000 hours and allows the fans to be laid flat or stand upright. - Turbo power adapter increases maximum fan speed and enables the fan to be powered through an AC outlet. - Dimensions: 4.7 x 4.7 x 1 in. per fan | Total Airflow: 104 CFM | Total Noise: 19 dBA | Bearings: Dual Ball ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01MZ6VNII | | Air Flow Capacity | 52 cfm | | Best Sellers Rank | #3 in Computer Case Fans | | Brand | AC Infinity | | Brand Name | AC Infinity | | Compatible Devices | Gaming Console | | Cooling Method | Air | | Customer Reviews | 4.7 out of 5 stars 2,535 Reviews | | Item Dimensions L x W x H | 1"L x 4.7"W x 4.7"H | | Manufacturer | AC Infinity | | Material Type | Rubber | | Maximum Rotational Speed | 1300 rpm | | Model | AI-MPF120P2 | | Noise Level | 19 db | | Number of Items | 2 | | Number of Packs | 1 | | Part Number | AI-MPF120P2 | | Power Connector Type | 2-Pin | | Product Dimensions | 1"L x 4.7"W x 4.7"H | | UPC | 854759004778 | | Unit Count | 1 Count | | Voltage | 12 volts | | Wattage | 1.6 watts | ## Product Details - **Brand:** AC Infinity - **Compatible Devices:** Gaming Console - **Cooling Method:** Air - **Material:** Rubber - **Maximum Rotational Speed:** 1300 rpm - **Noise Level:** 19 db - **Power Connector Type:** 2-Pin - **Product Dimensions:** 1"L x 4.7"W x 4.7"H - **Voltage:** 12 volts - **Wattage:** 1.6 watts ## Images ![AC Infinity, MULTIFAN S7-P Quiet USB Cooling Fan - Image 1](https://m.media-amazon.com/images/I/71Vz+SZfEWL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: So how does 52cfm + 52cfm + 130cfm?** A: Because these come with the plug-in adapter, which provides more power to the fans so they run faster than if you only run them off a USB port. Plug into the wall, they run at 65cfm each. Plug into the USB, they run at 52cfm each. They will also make more noise running off the wall wart. **Q: Do they sell a 12vdc version of this?** A: ive tested these with a 3rd party 12v 2a inverter. at first i was concerned whether the control module could handle the power but thus far its holding stable at full power over usb in an always on configuration. that being said i am not confident the wiring could handle the increased power load over an extended period. **Q: What's is the difference between the ac adaptor included in this compared to the ac infinity turbo adapter sold separately?** A: I believe they are the same. It’s just sold seperate also incase the fan setup you buy doesn’t come with one. This one does come with it. **Q: can you screw them onto wood for example?Seems like there are dampers where the location for screws should be.** A: Yes. the screws can be removed and you probably can use the holes for wood screws if you can find screws thin and long enough. I attached the fans to a cowling fashioned from Sheetmetal. they work great. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Quiet and powerful portable computer fans *by S***D on May 24, 2017* Fantastic, quiet, powerful AC and USB powered computer style fans.

But please read next paragraph. These fans and my AC Infinity blower are awesomely very quiet, not silent and not unheard especially if they were in a quiet room, but very quiet. Having have built custom cooling for my older AV cabinets and PCs for years and now needing a custom cooling solution for my home network gear yet not wanting the 80mm PC fan screen, and 120mm PC fan whispers, I stumbled across this brand and some solutions others had employed for their network gear. I was attracted by the PWM (DC power equivalent of VFD for AC) since I was very interested in a high, yet controllable, flow and this brand delivered: flow, control (O/L/M/H or optional controller), quiet. I am not disappointed. I have been studying and comparing this brand and their components and systems for nearly a year and I could not find a reasonable product on the market in the performance and price point as these. And, while they were not a perfect mounting fit for my needs, I was able to easily devise a secure, reliable and effective mount for each. Note: the twin fans have a limited, max distance placement due to being factory wired to the same harness. Not a problem in "as intended" installs, but definite consideration for custom uses. The equipment mine are mounted to are just under 12" fan-center-to-center and still have slack in the harness. 9-days of use and counting summary: my equipment is running FAR cooler than it ever has, and there seems to be far fewer (heat related?) Gremlins in my wired and wireless networks. Very Satisfied and KICKING myself for not getting sooner. Already planning to now install controller, and will be buying more ACI cooling equipment VERY soon to show my AV equipment the same love. Loving it. ## Frequently Bought Together - AC Infinity MULTIFAN S7-P, Quiet Dual 120mm AC-Powered Fan with Speed Control, UL-Certified for Receiver DVR PlayStation Xbox Component Cooling - AC Infinity Controller 1, Thermal Trigger for AIRPLATE, MULTIFAN, USB Fans and Devices.
