[SOLVED] Laptop staying very hot on Arch Linux

f9e3defb · 2011-12-18 18:43:26

Hello!

I installed Arch Linux on my laptop (Core i7 Sandy Bridge), and I'm noticing that CPU is running much more hotter than Windows 7. On Windows 7, the same machine runs on 50°C, but in Arch Linux it runs on 65°C, and the fan stay blowing air permanently (while on Windows it stays really quiet).

I changed the CPU frequency governor to ondemand and accepted all the tips from powertop, but the temperature stays high. There is no process using 100% of the processor.

Is there anything that I could do?

Thanks!

Check this:
https://wiki.archlinux.org/index.php/Fan_Speed_Control

Check the AUR too.

Seems similar.

I had a similar issue with my Intel i5 and the integrated Intel graphics. The following article solved my problem. It appears that they have had some hardware issues and therefore disabled some of the power reducing features. You didn't say what kind of video processor you have but this might help.

/dev/zero it's right

yes try this out https://bbs.archlinux.org/viewtopic.php?id=132077 it worked for me
Adapter: ISA adapter
Physical id 0: +43.0°C (high = +86.0°C, crit = +100.0°C)
Core 0: +40.0°C (high = +86.0°C, crit = +100.0°C)
Core 1: +43.0°C (high = +86.0°C, crit = +100.0°C)

If you are using the integrated intel graphics try adding these to your grub line to enable some more advanced power saving settings for the intel graphics:

pcie_aspm=force i915.i915_enable_rc6=1 i915.i915_enable_fbc=1 i915.lvds_downclock=1

Also if you aren't using laptop-mode-tools I recommend you do, it can have a huge effect on battery life.

EDIT: I should have clicked that phoronix link since it says the same thing I just posted lol

Great!! It`s works for me.

but the phoronix link said:

Similar to how PCI Express Active-State Power Management (PCI-E ASPM) can be forced by adding "pcie_aspm=force" to your kernel's boot arguments, to bypass the cause of the major Linux kernel power regression due to the ASPM change in Linux 2.6.38, there's separately a number of arguments that can be passed to the open-source Intel Linux DRM kernel driver to reduce the power consumption on that front. These enable power-saving features of the Intel Linux graphics driver that aren't enabled by default at this time, commonly because for some hardware configurations they can cause stability problems or other issues.

so maybe "pcie_aspm=force" is not necessary. Anyway, great.....

Thanks to triumphguy and bwat47.

I resolve the problem like this(for Intel Core i3 integrated graphics):

First, add some options in /etc/modprobe.d/modprobe.conf:

options i915 modeset=1
options i915 i915_enable_rc6=1 
options i915 i915_enable_fbc=1 
options i915 lvds_downclock=1

And in /etc/mkinitcpio.conf:

MODULES="...i915"
FILES=".../etc/modprobe.d/modprobe.conf"

...means what you already have.

finally in console:

$sudo mkinitcpio -p linux

reboot, cool and noiseless....:lol::lol::lol::lol:

kernel 3.2 is gonna bring rc6 by default on Ivy bridge and also on Sandy Bridge if VTd is disabled.

Please forgive me if I'm having a moment of stupidity here. It isn't quite clear to me why you've chosen to include the i915 module by altering mkinitcpio.conf. Would it not be sufficient to call it as one of the modules listed in /etc/rc.conf?

I`m a linux newcomer, and just follow this Wiki:

https://wiki.archlinux.org/index.php/Intel

I guess that just like prepostion(/etc/mkinitcpio.conf) and postpostion(/etc/rc.conf), should have same effect.

Okay, I hadn't seen that wiki entry before. I'm only fairly new to Arch myself, so I was wondering if I misunderstood something :-)

Thanks for all your help. With those suggested configurations, the CPU temperature went down from 65C to 54C, but the fan continues to be always on, making lots of noise. I did the procedures at https://wiki.archlinux.org/index.php/Fan_Speed_Control but it seems that my laptop don't have the ability to colect fan speed. Output of sensors:

acpitz-virtual-0

temp1:        +54.0°C  (crit = +100.0°C)
temp2:        +54.0°C  (crit = +100.0°C)

@bwat47 THANK YOU. I was getting 5.5 - 6 hours on my 9-cell battery. Adding those grub options just bumped my expected time (by reading smapi) to 8.5 - 9 hours! I will *definitely* have to do a burn-down test to see how long it actually lasts.

50% more battery is ALWAYS a good thing to see!!!
