RE: Raspi 4 CPU Temperature

Hi! I did some testing with PI 3 temperatures with and without a heatsink: http://www.moreware.org/wp/blog/2019/08/08/geeekpi-extreme-cooling-fan-kit-for-raspberrypi-3/

As you can see, when the PI (no matter wether 3 or 4) is under stress, it starts throttling (i.e. its working frequency diminishes). A heatsink (and/or a fan) is what you should use to get your PI cool and responsive: http://www.moreware.org/wp/blog/2019/07/21/raspberry-pi-4-nuovi-sistemi-di-raffreddamento/

You can also find some interesting system parameters (like temperature or frequency on different cores) from your Raspy using a shell script: http://www.moreware.org/wp/blog/2019/08/02/linux-controllo-live-dei-parametri-di-utilizzo/ BTW, this one works on ALL Linux systems, not only on Raspies.

I am doing some temperature tests on the Raspberry Pi 4 as well - with a heat sink. I'll post notes on it in the next day or two.
