Can fan trip points be changed in Puppy?
Can fan trip points be changed in Puppy?
On my laptop I notice that the second fan takes too long to come on when the processor is running at 100%.
From experience with Windows, the fan should come on at 55-60 degrees.
/proc/acpi/thermal_zone/TZ1/trip_points contains the following:
active[1]: 70 C: devices=0xc1240fe0
Can I change that 70 degrees to 55 degrees somehow?
Thanks

Give this a try:
Code: Select all
#!/bin/sh
modprobe ac
modprobe battery
modprobe fan
modprobe processor
modprobe thermal
#/proc/acpi/thermal_zone/THM0/polling_frequency
wmpower -no-meddling &
If you have /proc/acpi/thermal-zone/THRM/trip_points
then this might work for you.
It works on my hp n5250 laptop.
See Here for more info.

Code: Select all
echo -n "110:0:90:60:0" > /proc/acpi/thermal_zone/THRM/trip_points

Thanks trapster, that was the information I needed.
In my case I used
Not sure if these are right but the 56 degree temp is more like what windows was using to trip the fan.

Hi, just noticed that this method of changing the trip points is not working for me. During winter the laptop did not heat up enough to require the fan.
When I issue the command the trip points change as I wrote in previous post.
However, when the temperature reaches my new trip point where the fan should come on it does not.
cat /proc/acpi/thermal_zone/TZ1/trip_points shows that the original trip points have all been re-instated.
Now that the hot weather has arrived the laptop temperature is getting up over 60 degrees fairly easily.
Could someone please suggest why the trip points keep getting returned to original when they are triggered?

I just saw, that the trip_points file is refreshed every second on my Thinkpad.
Maybe that's why it is overwritten.

Mine does not "change" every second. I can't say I ever noticed when exactly it reverts back, but I did know that. I think I assumed every boot.
I just made a script. If I see the laptop getting a little too warm....I just start it from a console.
I suppose you could put it in /etc/rc.d/rc.local.

I saw this, being in ROX and clicking refresh frequently, I saw that the time changed every second.
I don't know how significant this is however.
As far as can see the first line entry says 97.
I suppose this is 97°C
But my fan turns on quite often.

I'm seeing the same 1 second updates that BEEM noted (I'm on a Dell Latitude c600/P3/850/256/full HD install of 3.01 Retro)... Can you share your script with us? This processor seems to run about 40 degrees hotter than it's sister laptop which is the same setup except for a 750 proc. I think it's probably okay by design, but makes me nervous sometimes. I'd like to have the manual override option if possible. Thanks in advance!trapster wrote:Mine does not "change" every second.

I created a text file with the code below, called it "temp", made it executable and saved it to /usr/local/bin.
I did check the properties and the times do change every time I hit refresh, but the contents of the file do not revert back to the original until I reboot.
I just type "temp" in a console when I see the temp creeping up higher than I prefer.
