You do of course realise these are promotional and most probably a case of

There are benchmarks that suggest this, but it very much depends on whether
you have background tasks, e.g. Beagle and built-in phone-home capabilities.

Yes, I have seen scripts that adjust and alter the behaviour of the fans. I
can't recall the names though...

'tar' is very resource-hungry, based on experience. Moreover, you can 'nice'
the task with the highest priority. Then again, Linux operates in a
round-robin fashion. The CPU always uses its full capacity given a
task/thread on the queue. It's only the priorities that vary. Attempts to
'pace down' the CPU are not trivial.

Unlike, for example, the use of a USB-attachable A/C that cools down the
motherboard... [sarcasm /]
