This read-only enumerated value reports the rollup status specifically of the processor cooling fan or fans, noting that a failed reading here always leads to a shutdown regardless of the general degraded-action setting. This is a stricter subsystem than the general system-fan status since CPU fan failure is always treated as shutdown-worthy. Seeing cpqHeThermalCpuFanStatus at failed means the admin should expect an imminent forced shutdown to protect the processor, unlike an ordinary system-fan failure which may just be logged.
