Avoid laptop overheating

Thank you for sharing tour experiences, I am rather new in this exciting project.

Prime95 prp testing is nearly always limited by memory bandwidth. If the main machine spends most of its time running P95, consider *under*clocking the CPU a bit to save a bunch of power. Slowing the CPU by 10% might save 16-20% power use (because voltage can be reduced too), with only 1-2% loss in work production. It's worth experimenting with such changes for machines that run these projects 24/7.

Indeed. I won't hire anyone who doesn't know how to do this kind of thing.

My review process is somewhat non-nominal.

Try Throttlestop to change your PL1 power limit with a lower value.
(This reduces your performance for other heavy tasks, like video encoding, as well. So you may disable Throttlestop temporally when running such tasks)
Intel XTU or Ryzen Master should work too. However I personally dislike XTU because it might lose your setting and revert to the default value on its own, about a month after your tweaking. This happened on quite a bunch of people including me.

Are you using a gaming laptop? Do you use it like a desktop computer instead of carrying it around?

If yes consider a cheap laptop cooling pad from Aliexpress (spending too much money on this won't help).

Even lifting the rear side of your laptop with 2 Coca-cola bottle caps helps a bit since this increases the amount of air entering your machine.

Thanks for your comment.
In my small homeoffice I have a capable computer. I use it for handling still images and to generate some YT-videos and the unused cycles for prime assignments.

My laptop is used for taking notes etc when I am not at home, however during the summer my laptop mainly sits on its shelf.
Primes on my laptop is just a sideproject. I have lowered its clock to 1.7 GHz, and the laptop now ticks along at a low but steady speed around 45 deg C.
