No this is not really about global warming.
On this Thinkpad W520 I can run three different KDE distro's, 16.04 and 17.10 are installed on the internal SSD, Neon is installed on an external (USB3) SSD.
17.10 is what I use most, Neon the least.
The past few days when I was playing around with PulseAudio and it's controls I noticed the temperature of the CPU was getting very high and causing throttling (above ~91degC).
I tried do do the same operations on 16.04 and noticed the temperature would be 10-20 degC lower.
I also noticed the temperature of the GPU would shoot up when the PulseAudio volume control and or equaliser GUI was open.
Closing them would bring down the temperature while the set audio would continue to function.
Next I tried the same with Neon and found it runs by far the coolest of the three options, like idling at around 55 degC where 17.10 runs over 95 degC and 16.04 around 75-85 degC.
It is especially with Firefox that I notice the throttling in 17.10 while on Neon it is really snappy.
All three use the nVidia390.25 drivers from the nVidia repository.
Regretfully the System Monitor only shows processes running on the CPU, not on the GPU.
As it is in this laptop the two processors use the same fan and the heat sinks must be pretty close together because an increase in GPU temperature will soon be followed by an increase in CPU temperature, even when the System Monitor shows no increase in CPU activity.
I've found various tools and especially commands that give information about the GPU.
Gives a list of applications currently running.
Tells me the amount of memory used and the temperature, same for:
But none that tells me which application is heating it up.
Anyone has ideas?
Oh yeah about global warming, I generate an excess of solar electricity so don't worry

Code:
