Dell Sunon 8020 12V replacement fan

This 8020 form-factor fan is built for Dell systems that specify the Sunon MF80201VX-Q010-S99 unit. It runs on a 12 V supply and draws 3.84 W through a standard four-wire connector. The design targets repair technicians and owners who need a direct drop-in replacement for a failed original cooler.

Four-wire PWM limit

The four-wire interface enables speed reporting and PWM control only when the host header supports it. Boards limited to three-pin voltage control will run the fan at full speed continuously. Buyers who need variable speed without PWM headers cannot use this unit as intended.
