Heat/Freq Tools?

Mint 19 Tara

Mint shutdown my laptop, due to overheating.

What heat-regulation, or cpu-frequency-regulation, tools are pre-installed in Tara?

- aside from TLP (which didn't prevent my machine from overheating),
- and aside from cpu-freq, which i was told is not adjustable in Mint 19 (true?)

thx

Other than the kernel (CPU governor) nothing much I believe. If you want to limit CPU frequency manually, that's possible in Mint 19 same as it has always been.

...not on 19 - but doesn't thermald come pre-installed / is supported in it anymore?

...also: not pre-installed, and furthermore, not for older processors, but...
Needless to say, do not over-do it with the values.

thermald is still around, of course, but that's more for when things are already going wrong, at least in its default (non-)configuration. I was more thinking of heat management during normal operation.

with governor? with cpu-freq?
i was told here that cpu-freq is just a monitoring tool, and changes in the cpu-freq dialog box have not effect.

thx all

I don't know that app, I can't answer that. I was thinking more low level, e..g

Code: Select all

echo 1000000 | sudo tee /sys/devices/system/cpu/cpu?/cpufreq/scaling_max_freq
But there are certainly tools to do it for you.

Be careful. I killed a laptop last year from overheating (if you search the forums for my posts you should find the threads), but luckily did not burn down the house!

I use external fans to blow extra air into the chasis/case of the laptop i now use, this is the most effective in terms of reducing temps.

Software stuff to think on is if using a discrete GPU try really hard to make it take the drivers and avoid using the software rendering/nouveu driver things (these were not allowing the discrete cards fans to function UNLESS i logged out the desktop environment to the LOGIN screen then they would ramp up hard (as it was so hot already)).

You can use psensor from the software manager (Menu>Administration>Software Manager) to keep an eye on hardware temps (it does not control fans or anything like that).

If on a laptop you could try the TLP stuff in my 'signature', that gave me about 5 degrees C less heat.

as far as i know, there are no tools for this preinstalled with tara, but i would highly reccomend installing conky (when set to panel mode, will display on top of most applications), makes a great OSD for checking that kinda stuff and is highly customizable
