HPE Fan Dual-Rotor

HPE Fan Dual-Rotor (822531-001) is a hot-pluggable fan module assembly for server cooling. Its dual-rotor design brings two fan rotors together in one module, while hot-pluggable construction supports fitting the module into a compatible system without treating it as a fixed, standalone fan.

This part uses a newer design that does not include or require a locking latch. HPE describes the original and newer system fan designs as functionally equivalent and says they may be configured together. That makes the part useful in systems where the two fan designs are present side by side. The confirmed details identify its construction and installation style, without specifying airflow, dimensions or supported server models.
