GPU and CPU high temperatures on Sony VAIO VPCEA1S1E

deluminathor · 2011-01-02 16:43:50

Hi,
I have a problem with my Sony VAIO VPCEA1S1E (with Intel Core i3 330M and ATI Mobility Radeon HD 5145 inside). The temperatures of CPU and GPU are higher under Linux than under Windows. As a result the fan is much more noisy.

Under Windows

When the system is idle the temperatures are about:

GPU: 52-58°C
CPU1: 42-50°C
CPU2: 36-45°C

In System Monitor tool there are 4 CPUs displayed and two of them (CPU1 and CPU3) remain suspended most of the time (while CPU0 and CPU2 are running all the time). The cooling fan is silent. This is OK.

Under Linux

When the system is idle the temperatures are about:

GPU: 67-69°C
CPU1: 55-57°C
CPU2: 35-57°C

I use xf86-video-ati driver and 2.6.36.2-1 kernel version. I also use cpufreq and powertop output looks as follows:

Suggestion: Enable Device Power Management by pressing the P key


Suggestion: Enable USB autosuspend for non-input devices by pressing the U key


Suggestion: increase the VM dirty writeback time from 5,00 to 15 seconds with:
  echo 1500 > /proc/sys/vm/dirty_writeback_centisecs 
This wakes the disk up less frequently for background VM activity

Suggestion: enable the power aware CPU scheduler with the following command:
  echo 1 > /sys/devices/system/cpu/sched_mc_power_savings
or by pressing the C key.

Suggestion: Enable SATA ALPM link power management via: 
  echo min_power > /sys/class/scsi_host/host0/link_power_management_policy
or press the S key.

Suggestion: Disable the unused WIFI radio by setting the interface down:
 ifconfig wlan0 down


Suggestion: enable HD audio powersave mode by executing the following command:
   echo 1 > /sys/module/snd_hda_intel/parameters/power_save 
or by passing power_save=1 as module parameter.

Suggestion: Enable the CONFIG_INOTIFY kernel configuration option.
This option allows programs to wait for changes in files and directories
instead of having to poll for these changes

I've also tried using Power Management tips for Radeon from Arch Wiki but the only option I could set in /sys/class/drm/card0/device/power_method file was dynpm and it made no effect.

It seems to me that the main problem is power management of the Radeon card as it interrupts CPUs very often and heats most. I suspect that the CPU temperatures may be increased because of the Radeon ones (but I may be wrong).

I hope someone can help with the issue...

I have the same problem and also my hard drive makes a noise "clicks" (by apm load cycles) so I think my laptop will die young ... and nobody answered me as to you

I have an ASUS laptop N61JQ and I was getting very high temperatures (95 degrees C).

I tried everything usual, cpufreq etc to no avail, till I installed PClinuxOS and the temperatures where around 60 centigrade.

Only difference: PClinuxOS had the catalyst driver installed, I had radeon.

Installed catalyst and surprise! The temperature is now 65 while computing and the fans are much quitter .

Perhaps is it your case ?

My 2 cent's.

I have catalyst too

The power management features of the open ATI driver are limited and I would bet that on Windows you are using the binary drivers from ATI. Thats why you can't compare Windows to Arch. If you want lower temperatures, I would try to install the proprietary ATI drivers.

I tried replacing xf86-video-ati with catalyst driver and it helped indeed Thanks Mektub!

@kismet010: Did you run aticonfig --initial (as root) after installing catalyst? It's very important. Before I run it the temperatures (and fan noise) were the same as with xf86-video-ati. Actually there are some more configuration steps that have to be taken after installing catalyst - check ATI Catalyst @ ArchWiki.

Now I'm bothering with dual head configuration because catalyst incorrectly sets the primary screen (i.e. the other way round as xf86-video-ati does) but it's for another thread.

of course, without xorg.conf X won't start

Recently I have switched to the radeon opensource driver again, because of the broken gnome shell with catalyst problem.

But now with the radeon driver and kms enabled I get nearly the same temperatures like with catalyst!

I have set the power level (profile) to low (like in the wiki descriped https://wiki.archlinux.org/index.php/Ra … MS_enabled).

Simply use this command:

 echo low > /sys/class/drm/card0/device/power_profile

To make it permanent write it into /etc/rc.local...

P.S.: I'm using radeon hd3470

Dejavu, it happens the same to me. Using Radeon HD 5730.

Go figure !

It decreases the temperature and fan speed indeed but it decreases performance as well. It's not a solution but only a workaround.
I would switch to catalyst driver permanently but I'm still bothering with its support for dual head mode. If someone is interested in the topic the discussion goes on at KDE forum.
