Haha fair question. I didn't make any special changes, I just left the lid open and put the laptop in a ventilated spot. I'm actually in the tropics, so I guess Lenovo scores some points here (the laptop is a Legion 5 Pro).

If you want to really cook your lap, try running Gentoo! Emerging (compiling) Firefox, glibc, gcc, Libre office and a few of their friends will soon show you how good the cooling is. A few years back cough I upgraded gcc from 3 to 4 and emerged system and then world. That was over 1200 packages. It took about a week. That was in the days when I used a Windows wifi driver and some unholy magic to get a connection. I parked the laptop on a table with the lid open and two metal rods lifting it up 6" for airflow. I left the nearby window open a bit too.

  Going off on a tangent: I used to use Gentoo in the past. I suspect, if you use one of the common processors, compiling your own binaries doesn't really give you any performance benefits, does it? (I have to admit I stopped using Gentoo mostly because it encouraged me to endlessly fiddle with my system, and it would invariably end up broken somehow. That's entirely my fault, and not Gentoo's. I switched to Archlinux as my distribution of choice, and I manage to hold myself back enough not to destroy my installation.)

    Quite a bit of performance. Generally Linux distro (and really all general purpose OS's) need to limit the CPU features they can to a minimum common baseline. Your machine support AVX512 instructions? Those instructions won't be used by the compiler because it's not available everywhere the software will run. By compiling yourself, you can specialize the compilation to the features on the machine. Beyond that the big win over performance even is customization. The most secure code, and the fastest code, is the code that isn't there at all. Do you really need your entire system to support LDAP authentication? Maybe... What about your local email daemon? Do you need that? Because cron does and since your mail daemon also has MySQL support built in, installing cron gets you the MySQL libraries. I don't use it anymore because of the overhead, but there are a lot of performance and security benefits to be had there.
