A practical guide to spotting heat buildup in AV cabinets and using the AC Infinity Aircom S6 to move warm air away from receivers and amplifiers.
When a warm cabinet becomes a problem
If your receiver or amplifier sits in a closed cabinet or on a tight shelf, you may notice the top panel feeling hot after a listening session. That warmth is normal to a point, but trapped heat can shorten the life of electronics and make some units behave unpredictably. Before you assume the worst, check whether the gear has room to breathe. If the cabinet is closed or the shelf is crowded, adding a component cooling fan like the AC Infinity Aircom S6 is a straightforward way to move heat out of the space.
The Aircom S6 is not a replacement for proper ventilation, but it addresses a common cause of AV rack overheating: hot air pooling around the receiver. It sits on top of the component and pulls heat away, which is especially useful when rear-panel clearance is limited or the cabinet lacks open space above the gear.
What the Aircom S6 does
- AC Infinity Aircom S6 - Component Cooling System: The AC Infinity AIRCOM S6 is a 12-inch component cooling fan that sits on top of a receiver or amplifier and moves heat out of the cabinet. This placement targets the heat that rises from the component, helping prevent it from recirculating inside a closed or tight space.

AC Infinity Aircom S6 - Component Cooling System - AC Infinity Aircom S6 - Component Cooling System: Two dual-ball bearing blowers deliver up to 100 CFM at a rated 20 dBA. That airflow is enough to push warm air out of a cabinet without adding distracting noise during quiet listening.
- AC Infinity Aircom S6 - Component Cooling System: The steel chassis is just 1.5 inches tall. A slim profile means it can fit on top of a receiver even when shelf height is limited, which is common in AV racks.
How to tell if your gear needs active cooling
Start by feeling the top and sides of your receiver after it has been running for an hour. If the surface is uncomfortably hot to the touch, or if the cabinet itself feels warm inside, heat is building up. Also listen for a fan inside the receiver that seems to run constantly or never slows down; that can indicate the unit is struggling to stay cool. These signs do not automatically mean damage, but they suggest the current setup is not giving the gear enough airflow.
Before adding a fan, make sure the receiver has at least a few inches of clearance above and behind it, as recommended in its manual. If that is not possible, the Aircom S6 can help by actively pulling heat from the top surface and pushing it out the back. Keep in mind that the Aircom S6 is designed to sit on top of a component, so it works best when there is a flat surface and enough room at the rear for air to exit.
Setting up the Aircom S6
- Place it on top of the receiver: Center the Aircom S6 on the receiver's top panel. The 12-inch width fits most standard components, and the 1.5-inch height keeps a low profile.
- Check rear clearance: Make sure the back of the cabinet or shelf is open enough for the blowers to push warm air out. If the rear is blocked, the fan cannot move heat effectively.
- Connect power: The Aircom S6 uses its own power connection. Route the cable away from signal cables to avoid adding noise.
- Listen and adjust: At 20 dBA, the fan should be barely audible from a normal listening position. If you hear it more than expected, check that nothing is pressing against the blowers or blocking airflow.
What the Aircom S6 will not fix
The Aircom S6 is a cooling aid, not a cure-all. If your receiver is faulty or has a failing internal fan, external cooling may mask the symptom but will not repair the underlying issue. Similarly, if the cabinet is completely sealed with no venting at all, the fan will simply move hot air around inside the enclosure. In those cases, improving cabinet ventilation or relocating the gear is a more effective long-term fix.
Also consider that the Aircom S6 is designed for components that generate moderate heat. If you have a high-power amplifier that runs very hot by design, check its manual for specific cooling requirements. The Aircom S6 can help, but it should not be used to exceed the manufacturer's recommended operating conditions.
Common questions about the Aircom S6
- Will the Aircom S6 make noise?
- AC Infinity rates it at 20 dBA, which is roughly the level of a quiet room. Most listeners will not notice it during music playback, but in a silent room you may hear a faint airflow sound.
- Can I use it with any receiver?
- It works with most receivers and amplifiers that have a flat top surface and enough rear clearance for air to exit. Check the dimensions of your component and the space above it before placing the fan.
- Does it replace the need for cabinet ventilation?
- No. The Aircom S6 moves heat out of the component, but if the cabinet itself has no way for hot air to escape, the benefit is limited. It works best when used in conjunction with some cabinet ventilation.
- How do I know if my receiver is overheating?
- Signs include a top panel that is too hot to touch comfortably, frequent thermal shutdowns, or a receiver that sounds distorted after long use. If you notice these, turn off the gear and let it cool before investigating further.
