Fan numbering

To provide sufficient airflow to the system, the server is populated by four fans by default. There are a total of six fans.
The fans can either be standard, single-rotor fans or high performance, dual-rotor fans. Mixed fan configuration is not
supported.
The arrow points to the front of the server.

Fan and heatsink requirements

CAUTION: To maintain proper system cooling, install the correct fan and heatsink types required for specific
hardware configurations.
