This object reports the simple health state of a specific cooling fan identified by the paired riserFanIndex, returning either ok(1) when the fan is running normally or fail(2) when something is wrong with it. It's the value an administrator or monitoring system checks to catch a failing fan before the resulting reduced airflow causes overheating in the chassis. For example, if riserFanStatus for fan index 2 reports fail(2), that fan needs physical inspection or replacement soon to avoid thermal problems.
