First Law of Systems Programming:
Never test for an error condition you don't know how to handle anyhow.
If the disk reports that it is over-temperature, *what can you do about it*?
If a CPU gets too hot you can reduce the clock frequency. You don't have that sort of option on a disk drive - especially from inside the kernel. You can't change its rotation rate, and throttling I/O won't significantly change the temperature (but can hang the system if writeback of dirty pages stops....)
