Arch Linux – Is It Possible to Control These Temperatures?

arch linuxhardwarepower-managementtemperature

As far as I know, it's not possible to enable fancontrol service or something like that for some HP Laptops, I'm using one such piece. While rendering a 6 min long clip in kdenlive, sensors readings were almost never under 80 degree:

in an ambient temperature of around 22 degree on a running 5 fan cooling deck.

EDIT 1:

I've given it another try with another 18 min long video in kdenlive, it took about 11 min to produce and several times temperatures rose up to 100 degree.

I'm using this one. It's an integrated Intel HD 530 and a dedicated NVIDIA.

Normally, when I read or write documents, execute C#/Qt code, it sticks around 35 degree and when I watch video, it's almost never less than 45 degree.

EDIT 2:

It doesn't do that much if I use GPU accelration in shotcut instead of CPUs in parallel in kdenlive, it took less than 2 and a half min to render the same 18 min video in shotcut and here's a snapshot of readings:

I don't know what iTCO_wdt and iTCO_vendor_support actually do BUT it looks like CPU temp reaches 100 degree less frequently if I keep those (nmi and soft) watchdogs enabled!

How long CPUs can run on an average temperature of 95 degree?

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.

Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no):

Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.

Some hardware monitoring chips are accessible through the ISA I/O ports.
We have to write to arbitrary I/O ports to probe them. This is usually
safe though. Yes, you do have ISA I/O ports even if you do not have any
ISA slots! Do you want to scan the ISA I/O ports? (YES/no): 
Probing for `National Semiconductor LM78' at 0x290...       No

Probing for `Winbond W83782D' at 0x290...                   No

Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.
Do you want to probe the I2C/SMBus adapters now? (YES/no):

what to do next?

Best Answer

There are options

Assuming the fans are running at full speed, manually controlling the speed won't do anything better. In general, you have three options:

Increase heat flow
Increase cooling area
Decrease heat generation

With a laptop, your options regarding 1 and 2 are very limited. You may want to check the air-flow. There might be dirt in the cooling fans. There also is the possibility that the thermally conductive glue is worn out. If this happens, the CPU heats up but the air blown out of the device is cool.

I recommend exploring option 3. Use CPU frequency scaling or – in case they exist – the overclocking mechanisms of the BIOS to underclock the CPU. The rendering process will obviously take longer, but the system will stay cool.

For nVidia GPUs, you can also chose performance profiles and – sometimes — clock speeds.

FreeBSD throttle cpu clock on high temperature

I had a similar problem in that my firewall (an old laptop) would shut down due to CPU overheat. I used the following steps to solve the problem, valid for the pfSense firewall:

1) Download FreeBSD cpu-speed.sh file from GitHub by dreamcat4

2) Create file cpu-speed.sh, and paste contents from source linked in previous step, through pfSense management interface, using Diagnostics >> Edit File

3) Enable execution of file cpu-speed.sh in fSense management interface, using Diagnostics >> Command Prompt and the command $ chmod +x /[path_to_file]/cpu-speed.sh

4) Check available CPU frequencies by running $ sysctl dev.cpu.0.freq_levels in Command Prompt

4) Run file cpu-speed.sh [valid_CPU_frq] using command $ cd /[path_to_file] && ./cpu-speed.sh [valid_CPU_frq]

5) Check current (new) CPU frequency using command $ sysctl dev.cpu.0.freq

6) Done.

I chose the min acceptable CPU core frequency for my CPU, and was able to permanently reduce the CPU core temp of my CPU from +90 C to < 60 C.

EDIT: To avoid dead links in the future, please find the code by dreamcat4 (as linked above) for file cpu-speed.sh below:
