CPU Overheating Problem When Running 4 CPU Intensive Threads with Latest Untained Kernel

[David Harel]

I am on the business for over 30 years. At the time, we knew that the only
way to break hardware by any software was to set bad frequency to the
monitor.
Afaik the nice command can't reduce cpu usage. It only allows other
processes/threads, would there be any, to get more cpu. Still, if no other
process requiers cpu your cpu intensive tasks will get all that is left
available resulting in high frequdncies and heat.
I would guess that either the cpu mentioned is faulty or that Intel stopped
prodicing durable cpus.

If nice is not enough for your process, ask it to be verynice:

"verynice is a nice(1)-like utility to throttle long running processes
beyond what can be achieved by nice(1), by repeatedly suspending and
resuming the process."
