Currently my main OS is openSUSE 15 on a Samsung laptop with an AMD A8 processor. I have become more and more fed up with systemd and btrfs so am attracted to Devuan and therefore to Refracta.
So I downloaded the ISO for refracta9 from sourceforge, burnt it to disk and ran it for long enough (maybe only an hour) to decide I liked it enough to install it in a partition on my hard disk. Did so, though with considerable trouble as my laptop kept turning off (overheating I assume) while transferring files. It shut down 3 or 4 times on different attempts. I did eventually manage to get it to complete the installation by adding an extra fan running at high speed to increase the cooling.
I logged onto the installed version and opened Firefox and the laptop shut down.
Further attempts led me to lm-sensors and on Refracta9 at the xfce desktop I have a CPU temperature of 79C. So no big surprise that the laptop shuts down when asked to do anything hard.
In openSUSE, again at the xfce desktop, the CPU temperature is more like 47C. That rises to the high 60s when working hard and I have managed to overheat the laptop once or twice running games under wine but that is maybe twice in 5 years. As I type (i.e. with a browser running) it is registering 56C
I downloaded Refracta8_NoX and that runs at 65C when at the command prompt. (Live disk - not installed)
I downloaded Refracta 8.3_xfce and that runs back up at 79C. (Live Disk - not installed)
Both the openSUSE measurement of 47C and the Refracta9 measurement of 79C were taken when the CPU was running at 1.4GHz - which is its idle speed.
The standard fan on the laptop runs distinctly faster when Refracta is running than when openSUSE is running.
The actual figures could vary slightly I am sure, but there is a pattern there, Devuan, or Refracta runs hotter than openSUSE. Can anybody suggest a reason for this or what I can do to correct it?
