To find the best home theater fan, you should consider the amount of heat you need to reduce, the space you have available, and the noise that a fan can introduce. You should typically look at the cubic foot per minute (CFM) rating for any fan you consider purchasing to see how well it can cool a system compared to other units. The measurements and dimensions of a fan are also important in regard how it can fit in the space you have. You should also look at the noise produced by a home theater fan, in terms of decibels (dB), before purchasing it.
A home theater fan typically refers to a unit used to cool off components of a home theater, such as a television, media player, and computer controller. One of the most important things you should look for in such a fan is the quantitative measurement of how well it can cool off a device. This is typically expressed in terms of a cubic foot per minute (CFM) rating that indicates how much air volume, in cubic feet, the fan can move in one minute, provided adequate ventilation. Higher CFM ratings usually equate to greater cooling power for a home theater fan, so you can use this value to compare different fans and find one that meets your cooling needs.
You should also look at the size and overall dimensions of any home theater fan or cooling system before making a choice. The size of a system is important because it usually impacts the number of individual fans on a unit. Some systems are fairly modular, allowing you to add individual fans as needed to compensate for additional heat contributed by new components in a home theater. You should choose a home theater fan that is large enough to cool off all aspects of your system, while fitting within any size limitations you may have.
It is also quite important that you consider the noise produced by a home theater fan before utilizing it. Sound produced by something is typically measured in decibels (dB), with higher values indicating louder noise. Anything below about 30dB is usually quiet enough to not be heard over the sounds of a movie or other form of home entertainment, though lower values are preferable. As you compare different types of home theater fan, you should keep in mind that decibel measurements do not increase linearly, so a difference of about five decibels is noticeable and an increase of 10 dB indicates sound volume that has about doubled.
