Compare airflow (CFM) to Noise levels (dBA) to determine the best option.

Performance: Silent operation with moderate airflow to circulate air preventing heat buildup.
Recommended for ccoling where temperatures are not exceeding 100?F.
Common applications: Home Audio systems, Recording and Broadcast Studio, Sound sensetive environments

Performance: High airflow to provide cooling for heat problems. Audible fan noise, but not very loud.
Recommended for ccoling where temperatures are exceeding 100?F.
Common applications: Servers, Network switches, Radio Equipment, Amplifiers
