How to increase Fan speed | HP Travelmate 8510p

Hi everybody,

I post here because I have an issue that last from more than year with the temperature of my CPU. It's always near 50/60 when I'm lucky, and it can go to 90 degree and make the laptop crash when I'm running costly applications (like compiling stuff or playing games).
I would like to force the fan to run faster, like it was when I was running windows on the same laptop, so that the CPU (and also at the same time the keyboard which is burning my fingers) stay cooler.

Here is a sensors I just made :

DeepThought# sensors
radeon-pci-0100
Adapter: PCI adapter
temp1:        +39.0°C 

coretemp-isa-0000
Adapter: ISA adapter
Core 0:       +61.0°C  (high = +105.0°C, crit = +105.0°C)
Core 1:       +63.0°C  (high = +105.0°C, crit = +105.0°C)

So it's seams the issue is realy the cooling of the CPU.

I tried stuff described here : https://wiki.archlinux.org/index.php/fan_speed_control but it seams I havent any PWM control on my laptop, or otherwise some drivers are missing :

DeepThought# pwmconfig
# pwmconfig revision 6166 (2013-05-01)
This program will search your sensors for pulse width modulation (pwm)
controls, and test each one to see if it controls a fan on
your motherboard. Note that many motherboards do not have pwm
circuitry installed, even if your sensor chip supports pwm.

We will attempt to briefly stop each fan using the pwm controls.
The program will attempt to restore each fan to full speed
after testing. However, it is ** very important ** that you
physically verify that the fans have been to full speed
after the program has completed.

/usr/bin/pwmconfig: There are no pwm-capable sensor modules installed

So if you have any advice, any method to try, I'll be happy to hear about it

Thanks,

Rexilion

You could perform a manual search:

find /sys -iname \*pwm\*

Run the command as root and post the output here.

The only alternative I could come up with:

- Use a scaling governor to prevent the cpu from scaling to it's highest frequency
- Disassemble the laptop and replace the old thermal pads / thermic paste with new thermic paste. In my experience, this has yielded outstanding results.

The output is empty (nothing found).

I did it and it helped a bit, but doesn't solve the problem, and don't last long.

Pretty strange that I cannot force the fan to run at the highest speed.

I may try that.
