Throttling RPi4 CPU to Avoid Overheating

[MPJ Grégoire]

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,

You could bye a housing with ventilator and a small device to turn the
ventilator on when the the temperature reaches a certain value. There is a
small Python script that reads regularly the temperature and turns the
ventilator on till it reaches a configurable lower temperature.

Hello again,

I believe I have a solution. First I installed temp-throttle.sh from
http://seperohacker.blogspot.com/2012/10/linux-keep-your-cpu-cool-with-frequency.html?m=1 .
Thermal shutdowns became rarer, but to eliminate them completely, I
also bought an aluminum case.
