Quiet Cabinet Cooling Fans That Are Worth Buying

When you have a bunch of electrical or electronic equipment such as home theaters and audio video equipment placed in a cabinet, you’re going to end up with an over-heated enclosure because of all the heat emitted by these working devices. Overheating causes them to fail functioning eventually. The safe way to ensure this doesn’t happen is by creating an airflow within the enclosed space, with the hot air moving out as much as possible.

You could leave the cabinet doors open to let out the heat, but the smart choice would be a cabinet cooling fan system that will work far more efficiently. These devices exhaust the heat out into the environment and draw ambient air into the enclosure. This keeps the equipment contained within it at a normal temperature, without overheating, and promotes efficient operation. It’s a simple yet economic solution to manage the heat for several applications.

Optimal Positioning and Configurations

Ideally, a fan system designed for ventilation must have an inflow in addition to the exhaust. The most effective setup would be placing a fan near the top of the cabinet to exhaust the hot air out, and one near the bottom to let air flow in. Warm or hot air is less dense and rises up; cold air settles at the bottom as it is more dense. An efficiently designed cooling system will rapidly exhaust warm air from the top and push cooler air in from the bottom.

Suppose your cabinet fan system has only one fan, it would be suitable to configure it at the top to exhaust the hot air out. Additionally, drill holes around the bottom of the cabinet to intake air would be a good idea for ventilation. With the air pushed out, the pressure within the enclosed space is reduced; with the natural movement of air from high to low pressure areas, ventilation holes let the outside air flow in.

What to Ensure Before Using One?

There are certain criteria that must be considered before using a cabinet cooling fan system. The ambient temperature and humidity level must be lower than within the cabinet that must either be indoors or have limited exposure to the natural elements. While exposure to corrosive materials must be completely avoided, there must be little or no risk of exposure to airborne contaminants or hose spray.

In case of extreme environments or locations where spraying of water or cleaners is done regularly, such a device not might not be appropriate. Essentially, the focus of your purchase must also be a quiet cooling fan system.

Suitable Applications

The most common type of cabinet fans are those that are used indoors to protect electrical or electronic components from overheating. This includes heat control for home theater systems, televisions, stereos, and audio video cabinets. On the other hand, there are models that are suitable for indoor or outdoor use. Portable substations used at construction sites, concerts, large outdoor events, or a manufacturing plant for power distribution require filtered fans.

Huge spaces such as hospitals, parking lots, stadiums, airports etc. have lighting contactors that control the lighting load. The overheating of this equipment can be avoided with the use of cabinet cooling fans. This also works for cooling electrical components in an electrical power system such as fuses, circuit breakers, surge protectors etc. and for wiring and junction boxes that are located indoors or outdoors.

The Best Ones Around

Cabinet cooling fans suit the thermal management requirements of a range of electronics. This is a far more affordable option to the use of air conditioners or heat exchangers. Here are some of the highly rated devices available in the market for varied needs.

AC Infinity Airplate S3

AC Infinity Airplate S3

This 6″ quiet cooling fan is well-suited for home theater AV cabinets. With a controller, you can select the appropriate speed of the fan for the required level of airflow and minimal noise, to suit different applications and environments, with the noise level specified to be around 18 dBA. The ultra-quiet UL-certified product contains dual-ball bearings rated at 67,000 hours that let the device be mounted vertically or horizontally with ease.

The AC Infinity axial fans that are contained within an aluminum frame that has been CNC machined, are quality approved with UL certification. The final product has a black finish and a wall outlet or a USB port can be used to power the unit. This quiet cabinet cooling fan also includes a Turbo adapter that boosts the fan’s speed by 25%, with a wall adapter input of 100 to 240V AC required. Pair it with an AC Infinity Thermal Controller, and this system can be used for cooling home theater and AV cabinets.

Connection of Additional Units

When the cabinets need more airflow and one unit may not suffice, connecting additional units of the Airplate S and T series will be more effective. With the single fan Airplate S1 model, up to four units can be daisy chained to share the same USB power source, while a single thermal controller and wall outlet power source can be shared by up to six units.

The S5, S7, and T5 models contain two fans and the S9 model contains three fans. Avoiding overload when more than four such fans are connected could be done by setting the inline speed controller high. This combinational use expands the areas of use to racks with computers, amplifiers, and receivers as well.

An Added Advantage

A plastic template that comes along with the fan aids in positioning of the drill holes, easing up the installation process. Also, while the fan is set to exhaust hot air out of the enclosure, it can be reversed for intake of air by using a screwdriver.

AC Infinity Airplate T7 Home Theater And AV Quiet Cabinet Cooling Fan System 12″

AC Infinity Airplate T7 Home Theater And AV Quiet Cabinet Cooling Fan System 12

Yet another noteworthy product of the AC Infinity Airplate series, this model quietly cools AV cabinets, with dual-ball bearing fans and a PWM motor to reduce noise while doing so. The additional feature of the T-Series models is the digital LCD controller that provides automatic thermostat control as well as the fan’s speed control, along with three back-light settings.

Like the other AC Infinity Airplate models, this one also has a UL-certified fan system, with an ultra-quiet operation, where minimal noise is preferred. The automated programming feature self-adjusts the cooling power as per the temperature variations around. An black aluminum frame that is CNC finished comes around the fan and the controller.

Thermal Controller

An on-board processor for the controller is responsible for monitoring the temperature actively and intelligently performing the fan speed control. In addition to the LCD display, the other features include an alarm system, six fan speeds, and a display lock/off. There’s also a power failure memory and two buffer options.

Connection of More Units

Larger cabinets or ones that have too much electronic equipment, need more airflow.
