3 1/2" .17 A 12 V DC Fan

 

Excellent for exhausting the hot air out of cabinets where the audio/video equipment is located.

The larger size fan allows you to be able to run the fan quietly while still moving alot of air in comparison to small noisy computer fans.

The speed of fan and loudness of the fan can be adjusted by an adjustable power supply like the Avparts ADC-UNI-600MA.
This fan is designed for constant usage which is great especially if you have a cable HD DVR box or a satellite HD DVR box.
