I Ran Modprobe Fan, The CPU Fan Slowed! Will It Over Heat?

[EdFromHouston]

This is edited from the post last night.

I just updated to 2.13 on my home PC, a HP a310n pavilion.

I ran modprobe fan which I just discovered.

The CPU fan that has been driving me crazy slowed down. If I run modprobe fan, modprobe thermal, and modprobe processor in rc.local will my cpu overheat?

If it will overheat is there a command for the wmpower.pup to show the temperature? This is what I'm getting:

sh-3.00# wmpower

Welcome to wmpower version 0.3.1...
No power management subsystem detected

wmpower: No power management support...
sh-3.00#


Puppy is much better quiet and this is the first time I have ever been able to cut the fan off.

Am I burning up my CPU by running modprobe fan? In other words do you think it will speed up when it gets hot with the above commands in rc.local?

Maybe you are. Are you sure it's off, or is it just slowed way down?

Try "wmpower -no-meddling"? See:

http://wmpower.sourceforge.net/manual.php

Aren't you supposed to run wmpower after the modprobes, not before?

This is what I run in my rc.local:

Code: Select all

modprobe ac
modprobe battery
modprobe fan
modprobe processor
modprobe thermal
sleep 3
#wmpower -no-meddling -l

Of course wmpower is an xwin application and can't be run in this script (why I have it commented out). You have to put that command somewhere else, in the .jwmrc or something like that. Try searching the forum.

Maybe it's thermal you want. My fan is off or very low, but when wmpower shows it is getting hot enough (I forget the exact point) it does turn the fan on. But I think it is the thermal or fan module, not wmpower, doing it.

I'm a bit shaky on how this all works...

Now I understand. The 'modprobe fan' command slowed the fan down and not off.

Wmpower just shows what the pc is doing.

I typed in modprobe fan, modprobe thermal, and modprobe processor in the console and then typed in Wmpower. The fan is quiet but Wnpower doesn't detect it.

I'll check arround and learn what I need to do.

I was just so relieved last night to finally get the fan to quit sounding like a twin engine prop plane that I didn't get my facts right before posting. I'll see if I can edit the title.

Maybe you don't even have ACPI? Is that what that error message means?

I think it is because my system is a home pc and wmpower is for laptops.

My PC is homebuilt. When I modprobed the whole list Paul provided it worked. I tried skipping the batteries part because it doesn't have them, but then it wouldn't work.
