Description

While running a write workload to all disks in a cosmo-b we noticed that the fans will oscillate up and down.
The fan speed will vary between 4500 and 5500 RPMs. We have even seen a spike of higher numbers that then return back to the baseline.

Research direction

No files, tests, or entry points are named. Reproduce the reported write workload on a Cosmo-b, then trace the fan-control behavior and its response to changing temperatures or load; done means fan speed remains stable under an even workload without unexplained spikes.
