Questions about this item

What does the 12 V rating mean when the EFB0412LD fan is installed in a 1U chassis?

The fan is designed to run directly from a 12 V rail, drawing 0.08 A, so it fits standard server power distribution without extra converters.

How does the 4020 form factor limit the airflow this mute switch fan can deliver?

At 40 mm square by 20 mm thick, the EFB0412LD fits tight 1U bays, but the small blade diameter caps maximum airflow compared with larger fans.
