Overheating problems with CPU

[LastGunslinger]

Ive done a fair bit of a research and come up short unfortunately, Synopsis: My laptop HDD went poof a few weeks ago, thankfully i had an SSD installed, but its too small to run windows stably without a new drive. So i had to turn back to Kubuntu for the moment, and the problem i've been having lately is overheating issues with my processor, its got an auto turbo boost in it, and linux wants to run it at max clock speed all the time, normally this wouldnt be an issue, because buy a laptop cooler right? Clean the vents right? Let me explain further, my financial situation is tight, im NOT ABLE to buy any new hardware or components, or a new laptop, or even cheap materials to rig up an AC cooler for my existing crappy cooler to begin with. My thermal paste is good, checked it yesterday, fan speed is at maximum already, yes im also aware of trying to adjust clock speed from BIOS but it flatly refuses to let me to let me modify the clock speed in BIOS, probably due to the turbo boost.
So, i dont want to overclock, i want to underclock my processor to run at a consistent 1.8 Ghz as apposed to the constant (and mildly frustrating) 2.4. But i've been unable to find any software native to linux, any suggestions on how to PERMANENTLY lower clock speed? Yes yes, im aware that modifying these sorts of things can be dangerous if done incorrectly, lets skip all the warnings and 'beyond this point be dragons' speeches. My processor is running at a constant temp of 65 to 70 Celsius, which can be dangerous on its own over time.
Thank you in Advance

Try the power save governor

echo powersave | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor

this will give you a list of options for the above

cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors

there may be a option in your bios to disable turbo

When i tried to boot BIOS this time, all it showed me was a gray clipped screen, so yay for that. Looks like BIOS is out of the picture entirely now
So far as powersave goes, it doesnt help either. Clock speed is still a constant 2.4

What kind of laptop and CPU are we talking about here?

This is probably not dangerous for a laptop. Laptop CPU's are made to run at much higher temps than desktop counterparts.

+1, we need to know this. In addition to what pqwoerituytrueiwoq asked for, we also need to know the CPU frequency scaling driver, so both and for example:

doug@s15:~/temp$ cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_driver
intel_pstate
intel_pstate

I was actually not aware of this fact actually, i've only ever had desktops until now, whats the normal meltdown or beyond this point be dragons temp for most laptop CPUs?

Are the outputs of both
Not entirely sure how to get the output of each result, im not the most knowledgeable in the inner workings of Kubuntu, sorry about that

105 degrees C for your particular processor. You can use turbostat (in the linux-tools-common package) to obtain more details.

You can disable turbo with this command:

echo "1" | sudo tee /sys/devices/system/cpu/intel_pstate/no_turbo

You can further (or instead) reduce the maximum clock rate with, for example, this command:

echo 70 | sudo tee /sys/devices/system/cpu/intel_pstate/max_perf_pct

CPU MHz: 1424.413

That seems to indicate the CPU was running at 1.4GHz when you ran the command.

It varies. Tjunction is listed as 105C for your CPU: https://ark.intel.com/products/65707...up-to-2_60-GHz
I wouldn't be comfortable going above 90C for extended periods of time though. If you were overheating, your laptop would throttle the CPU or shut down completely to prevent damage.

[LastGunslinger]

Very useful to know. Turbo has been disabled, thank you for your help, all of you, and please pardon my dense nature and ignorance with this subject. I will mark this thread as SOLVED
