Product description
A quiet fan system designed for cooling receivers, routers, game consoles, and other AV components. Protects components from overheating, performance issues, and shortened lifespans. Programming features two thermal trigger modes and four speed control options. Contains two dual-ball bearing fans with PWM-controlled motors to minimize noise. Dimensions: 11.6 x 6.3 x 1.5 in. | Exhaust: Top | Airflow: 140 CFM | Noise: 19 dBA | Bearings: Dual Ball Product Description A quiet cooling fan system designed to be placed on top of AV components such as receivers, routers, game consoles, and AV cabinet components. Maintaining an optimal temperature for components prevents overheating, ensures constant performance, and extends their lifespan. The controller on the front of the cooling system features a smart thermostat trigger and fan speed control. The steel enclosure houses two dual-ball bearing blowers that pull heat out of the component and exhausts out the rear. The dual ball bearings also allow this fan system to be mounted horizontally or vertically. Its low-profile design enables the unit to fit in tight spaces. Includes corded power adapter to plug the fan system through an outlet. Intelligent Programming There are three programming settings available which includes two temperature trigger modes. The fans can also be set to run continuously or be turned off. Four fan speeds are available for each active mode and will determine the speed at which the fans run when they are triggered. This ensures optimal airflow and noise levels for your application. Design and Construction Each system features dual-ball bearing fans rated at 67,000 hours and are certified by CE and RoHS. Fans contain a PWM-controlled motor used to minimize noise during speed variations and are suspended in mid-air with silicone mounts to absorb vibrations. A low-profile design allows the unit to fit in applications with a limited height clearance. Aluminum and steel construction enables additional components up to 10 pounds to be stacked on top.

Reviewed in Canada on June 2, 2025Verified PurchaseParfait pour refroidir.
- Reviewed in Canada on November 5, 2021Verified PurchaseAlthough this is only the 12” wide model, with only 2 fans & no electronic controls (just a preprogrammed temperature cycle), I decided to get this model as it was almost 50% off ($66, down from $120). My main surround sound amp is 17” wide (standard size) & puts out a lot of heat. Since getting this fan & running it on it’s smart setting (both LEDs lit), my amp now runs cold to touch! It’s amazing how much heat is dispersed. Plus, the fan doesn’t even need to run continuously. It cycles on & off as needed, mainly on the low setting. On hotter days, it might bump the fan up to the medium setting, before dropping back to low then cycling off. Very quiet: I don’t hear the fan at all. I liked this model so much, I bought 3 more at the discounted price, for my other surround sound amps. The amp in my bedroom always ran very hot, but now it’s also cold to touch, because it’ll cycle all the way up to medium-high (before cycling down & off). So far this fan has never needed to go to the highest fan setting. It’s a very well made unit with quality parts & feel. I’m sure it would look better if I had the larger 17” wide, 3 fan model, but those are currently over $200 each. For the amount of hot air this 12” wide fan moves away, it’s not necessary to buy the bigger model (aside from the standardized look to match the amp’s width). So glad I got this as long term heat will eventually wear out your modern day amp (I’ve gone through a few over the past 25 years compared to my 80s Pioneer amp that’s still working! - I’ve bought a few high-end Yamaha & Onkyo amps over the years). I’ve had these fans now for over 3 months & even with daily usage (my one amp is on for around 12 hours/day) they are all still working great. It’s not often that I’m this impressed with a modern product. I’d give it 6-stars if I could! I’ve since purchased a bunch of AC Infinity fans & controllers for my audio amp rack. These products are also of high quality & work very well.

- Reviewed in Canada on April 11, 2024Verified PurchaseI picked up the AC Infinity AIRCOM S7 to protect my new Pioneer LX305 from overheating. The setup was simple, and its design is impressively compact, fitting seamlessly on top of the receiver. What stands out is its quiet operation, thanks to the dual-ball bearing fans, which is a significant plus for any living space.
It features a smart thermostat and fan speed control, allowing for automatic adjustments to maintain optimal temperatures. This functionality gives me peace of mind that my new pioneer receiver will last.

5.0 out of 5 stars Excellent product and very good delivery!
Verified PurchaseOrdered from The supplier “International Store” on 鶹. Good delivery, followup and Customer Service. The product AC Infinity S7 is an excellent device perfect for my requirement to join the 4 x S5 fans from AC Infinity to cool my beastly Denon AVC-X8500h despite the Denon having 4 internal fans in the monolithic amp section. I customised the fans based on the internals of Denon X8500h. Yes, It is bit if an overkill. I prefer to pamper and treat my quality electronics like any living thing. All AC infinity products i have purchased so far have fantastic build quality, beautiful minimalistic appearance and solid functioning so far. The S7 came with a charger with AC input voltage rating 100-240v which means there is no issue using it in India. Satisfied with everything so far. Can not comment on the longevity yet. However, i am confident that the fans will last for years to come judging by the build quality.
Update: The Fans have been running nonstop these past 2.5 years without issues except for the charger that went kaput after 18 months of nonstop use. But the replacement was cheap(Rs.200)and easy to find as the Tatasky Set-top box original charger is the same one.

5.0 out of 5 stars Sehr ordentlich verarbeitet!
Verified PurchaseSieht top aus, wertet jedes System nochmal richtig auf. Kühlung ist hervorragend. Besonders die verschiedenen Modi sehr gut durchdacht. Zu hören ist er auch auf der untersten Stufe, aber auch normal da ja ein Luftstrom fließt. Für Deutschland ist kein Stecker bei, muss man sich gleich als Adapter dazukaufen. Könnte man ruhig erwähnen in der Artikelbeschreibung. Dann kann man gleich, vor lauter Vorfreude auf das Produkt, es sofort benutzen wenn es nach längerer Lieferzeit ankommt. Würde ich wieder kaufen, sehr zu empfehlen!

5.0 out of 5 stars A great piece of kit!
Verified PurchaseA brilliant piece of kit. I was using a laptop fan before but this is in a different class. Beautifully built, all metal. Fans are very quiet. Can be programmed to automatically come on when the temperature rises and then it goes off. Please note you do need a us to UK plug adapter as this comes direct from the USA. I'm very satisfied.
