Welcome to our AC Infinity AIRCOM S9 Review! In this in-depth assessment, our audio specialists examine the flagship AIRCOM S9 AV Receiver Cooling Fan with Thermal Trigger (17″ Top Exhaust) from AC Infinity. Designed for serious audiophiles, this heavy-duty, low-profile cooling system delivers class-leading 210 CFM airflow, whisper-quiet operation and smart thermal control to keep your high-performance AV receivers, game consoles and cabinet components running cool under pressure.
Build Quality and Design Elegance
The AIRCOM S9 sits elegantly atop your AV component with a slim 3.8 cm profile and a robust aluminium and steel chassis capable of supporting up to 13.6 kg. Its top-exhaust configuration harnesses natural convection—warm air rises… and the S9 channels it directly upwards, maximising heat extraction without intruding into tight rear rack spaces.
Performance and Acoustic Signature
Under the hood, three dual ball bearing fans driven by PWM-controlled motors generate an industry-leading 210 CFM of airflow at just 21 dBA—barely more than a whisper. The low static pressure of 1 mm-H2O ensures air slices through dense amplifier heatsinks, dissipating heat rapidly without the drone often associated with high-output fans.
Intelligent Thermal Programming
A standout feature is the front-panel controller with two thermal-triggered modes. Set your temperature threshold and let the S9 engage automatically when your receiver’s top plate heats up. For continuous operation, choose the fixed-run mode or switch off when not needed. Four distinct fan speeds per mode allow you to calibrate the optimal trade-off between airflow and acoustic discretion.
Who Should Consider the AIRCOM S9?
If you own a full-width AV receiver that runs warm under sustained loads—or you’ve got a rack full of heat-generating components—the AIRCOM S9 is a must-have. It’s ideal for 4K home theatre setups, multi-channel amplifiers and high-performance game consoles housed in AV cabinets with limited ventilation.
