What is a fan tray/module?

Explanation:
A fan tray/module is a hot-swappable assembly of cooling fans that provides airflow across components to remove heat. This modular design lets technicians swap a failing fan without powering down or opening the entire chassis, keeping airflow and temperatures stable. The fans direct air through the server’s hot zones—CPUs, memory, power supplies—to prevent overheating and to support redundancy. It’s not simply a fan tucked behind a cover, nor a CPU heat sink, and it’s not a power distribution unit; those other items serve different functions and don’t offer the same modular, replaceable cooling capability.
