While this is great for absolute silence, it does affect temperatures quite a bit. I have installed OpenWRT on the WRT32X for more control and features over the router and this includes temperature monitoring. On idle, the router stays at 92c in an ambient of 30. Take note, the router is placed in the open in the TV console, so it's not like it is closed up in a cabinet with zero ventilation. On maximum load tests, it can reach a maximum of around 110c (!!). Temperatures like this would significantly affect the lifespan of electronics so I am compelled to do something about it. Here is where I decided to get these cooling fans to help reduce temperatures to more sensible levels. I wasn't expecting what a difference it could make. I simply placed the fan on the top of the router where it sucks out the hot air from the router. Idle temperatures dropped from 92c to 64c. You can take a look at the temperature graph I have included. You can see when I plugged it in and the temperatures starting to decline gradually. I tried reversing the orientation of the fan such that it blows cool air into the router instead of sucking hot air out of it, but there didn't seem to be much difference, so I just let it suck the hot air out. The fans themselves are very easy to use. It is powered by a USB port, and the router conveniently has a USB port that I'm not using otherwise, so I plugged in the fan there. There is also an inline speed controller that allows you to set it to off, low, medium and high. I noticed that if I set it on low, the controller gets just a little warm, while on high it is cool. I'm guessing there's some kind of resistor in there that reduces the speed of the fan by diverting some of the electrical power to heat instead. Speaking of the fan speed, even on the high setting, it is still fairly quiet and moves a generous amount of air per fan. The fans come in a set of two, so I'm using one for the router, and the other for general ventilation to keep air moving around. The fans themselves have rubber feet and a metal grating in front to prevent accidental contact with the fan blades. The rubber feet also provids some distance between the fan and the device it is cooling so that air can pass through more easily. Overall, this is a really good buy and helps so much in keeping our electronics cool and extending their life. Review: really “cool” cabinet fan system - highly reccommend - This is a really “cool” cabinet fan system. We have a custom built-in entertainment cabinet in our family room. The top section has the flat screen LCD TV with the Wii equipment and the middle section has an audio system, TiVo, CD player and a VCR, (I know why a VCR). The new TiVo and the 25-year old audio system generate a fair amount of combined heat that I wanted to remove. I did a search on desertcart for cooling fans and looked at several options. Having a system that was temperature controlled and could adjust the speed of the fans was very attractive so I decided to focus on that solution and was very impressed with the features of the AC Infinity products. I ordered the AC Infinity AI-ATC, Fan Thermostat and Speed Controller, MULTIFAN S7, Quiet Dual 120mm USB Fan, and MULTIFAN S5, Quiet Dual 80mm USB Fan. Everything arrived in two days; the three items were well packed and arrived safely. Now I could actually see and test what I got and found they were even better than I had expected. The controller is a perfect size and flush mounts in my equipment cabinet. The temperature probe has a long enough wire to run it down and over to place on the audio amp and under the TiVo where the maximum heat is generated. The fans have large rubber grommets on each corner to stand on or mount with and no vibration is transmitted through. One set of fans are in the equipment section behind the equipment blowing air out through the equipment towards the open room. The second set is located in the TV section also blowing from inside through the TV towards the room. Running at full speed in a quiet room you can of course hear the mechanical fan and wind noise. However, when the audio is on, even at a comfortably low, watch the news level, the fan sound level drops below the audio program level and is no longer discernable. With the controller running in the “smart” mode the fan speed is reduced when the equipment temperature is within two-degrees (or four) of the desired set temperature. As they say on TV “Just set it and forget it”, the controller keeps the fans running as long as the equipment is generating heat above the set point. When the audio amp is turned off and the TiVo goes into stand-by the fans cool them down and then shut off. When I am able to locate my hole cutting drill I will add some ventilating holes in the top of the cabinet and between the sections in order to improve the circulation of fresh cooler air into the cabinet to improve the efficiency. I am so pleased with this cooling solution that I am ordering another setup for our weekend summer cottage up north at the lake. Again, there is an audio system but in addition there is a Magic Jack phone module and the cable modem / WiFi router generating heat. They are in a confined space that gets hot so I had placed a small fan in there to circulate the air. When we are there, I plug in the Magic Jack and turn on the fan. Now I will be able to automate the cooling. If you are looking for a great way to cool down your expensive equipment this is an inexpensive solution that I highly recommend. ## Features - Ultra-quiet UL-certified USB fans 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. - USB plug can power the fan through USB ports found behind popular AV electronics and game consoles. - 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 | B00JLV4BWC | | Air Flow Capacity | 104 cfm | | Best Sellers Rank | #17 in USB Fans | | Brand Name | AC Infinity | | Compatible Devices | Gaming Console | | Cooling Method | Air | | Customer Reviews | 4.7 4.7 out of 5 stars (8,114) | | Included Components | item | | Item Dimensions L x W x H | 4.7"L x 1"W x 4.7"H | | Manufacturer | AC Infinity | | Material Type | Rubber | | Maximum Rotational Speed | 1300 rpm | | Model | AI-MPF120A2 | | Noise Level | 19 db | | Number of Items | 1 | | Part Number | ACAIMPF120A2 | | Power Connector Type | 2-Pin | | UPC | 854759004341 | | Unit Count | 1 Count | | Voltage | 12 volts | | Wattage | 5 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:** 4.7"L x 1"W x 4.7"H - **Voltage:** 12 volts - **Wattage:** 5 watts ## Images ![AC Infinity MULTIFAN S7, Ultra-Quiet Dual 120mm USB Fan/w Speed Controller | UL-Certified, Dual-Ball Bearings, Noise-Absorption Pads for Receiver DVR, PlayStation, Xbox, Computer, Cabinet Cooling - Image 1](https://m.media-amazon.com/images/I/71w0uj5VPML.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: how much power do they pull? im worried about battery drain** A: 2.9 Watts .58 Amps Per fan. 3 to 7 volt DC. 52 CFM per fan. 1300 RPM. This is directly off the product tech page. **Q: Does the dual 120mm model come with an AC adapter?** A: Bad answers, or not up to date. This is USB powered but there is a dual 1200mm fan AC version , same company for a few bucks more. **Q: Can these be powered by an external battery pack?** A: Yes you can power them using an external USB battery pack (power bank). I have the two fans plugged into a USB power bank, with the adjustable inline switch on "H" High, and they draw approximately 0.45A or ~2.25W total. In theory a 10,000 mAh power bank can run these two fans on high for ~ 20 hours. **Q: What is the cord length between the fans please? Thanks...** A: Seems to be approximately 30 inches. ## Frequently Bought Together - AC Infinity MULTIFAN S7, Quiet Dual 120mm USB Fan, UL-Certified for Receiver DVR PlayStation Xbox Computer Cabinet Cooling - AC Infinity Controller 1, Thermal Trigger for AIRPLATE, MULTIFAN, USB Fans and Devices.
