What IS This?

This series compares (usually) 5 fans per episode on the basis of RPM, airflow (CMH) and pressure differential (degrees of movement). The focus of this series is to help people see how fans compare against each other for the purpose of exhaust performance. After comparing the 5, they are compared against all of the other fans that have already been compared.

Note: Here, pressure differential refers to the maximum movement by the air of a simple paper tool, where very few fans exceed 90 degrees from 0 (off).
