Throttling RPi4 CPU to Avoid Overheating

[MPJ Grégoire <mpjgregoire@theanvil.ca>]

Hello,

I have a RaspberryPi 4, running Debian Stable.  From time to time, the
system overheats under load and shuts down.  Is there software I could
run or a setting I could configure that would throttle back the CPU to
keep the temperature under (say) 85°C?

Thanks very much for supporting Raspberry Pi computers.

Sincerely,
