What should I check before ordering?
Compare the complete label, any additional version marking, mounting holes, frame depth and fitted connector. Dimensions, speed, airflow, pressure, noise and bearing need an exact version-specific document or a physical measurement where appropriate. Lead count alone does not establish PWM or tachometer functions.
