Planning to build a class H amplifier to power a Eighteen sound 21 inch subwoofer. Im looking for a good pro audio quality fan for long term usage. Can anybody recommend an excellent grade fan for very long term and reliable use.
Size and voltage plus airflow would be useful. Anyway fill your boots with this selection. Axial Fans | RS Components
Even a PC fan will be OK as they are designed to last a few years.
To preserve the fan, and reduce fan noise, it is recommended to add a temperaturecontrol to the fan. Not often there should be any need for the fan to run if the amp is reasonable well designed otherwise.
I kept a picture of the Classe CA2300 multi-channel amp because of the well engineered cooling tunnel. Note: a deep fan is used to deliver high air volumes "when needed". Yep, you can wireless control the amp with your phone or pad.
