Compact 50 mm case fan

The Fans KDE1205PFV2 measures 50 by 50 by 10 mm and runs on a 12 V supply drawing 1.1 W. A three-wire connector provides speed monitoring for system fan headers. It fits tight chassis where larger frames cannot be mounted.

Questions about this item

How often should the 3-wire switch on the KDE1205PFV2 be cleaned or replaced?

The 3-wire switch has no user-serviceable schedule; dust the blades and frame with compressed air every few months to maintain airflow.

What limits the 1.1 W KDE1205PFV2 during continuous operation?

Sustained use is limited by the 1.1 W motor rating and 50×50×10 mm frame, which cap airflow and heat dissipation.
