Recently, after some operations on my machine, its temperature began to raise. Let's begin with some information.
Machine caracteristics
- Sony VAIO SVE1511C5E laptop
- Intel Core i7
- 8Go RAM
- AMD Radeon graphics
- 500Gb hard drive
Current system caracteristics
- Latest Arch Linux (3.10.10-1-ARCH)
- Working with Intel Integrated Graphics (supposedly, I'm not sure I did this configuration correctly).
What I did until now...
A few days ago, I decided it was be time to abandon the classic "Ubuntu/Windows 7" dual-boot, and switched to Arch Linux, which I've used for quite a long time on other machines.
- I started by shreding the hard drive, to make it "clean". One pass random, one pass with zeros (from sector 2048 to the end).
- I installed Arch Linux, everything went fine.
But the problem occured after this. Back when I was under the Ubuntu/Windows 7 dual-boot, my computer's temperatures were reasonnable. I had sent the machine to Sony for repairs once (the fan was apparently broken), and since then, everything ran around 40/50°C (idle), and rarely reached 60/65°C during big tasks.
Now that W7/Ubuntu disappeared, these temperatures are nothing but old memories.
- When doing nothing (idle), the machine stays around 60°C.
- When working harder, it reaches 75°C/80°C very quickly.
- I did not try the heaviest tasks such as running IDE's, compiling big programs, and so on.
Right now, as I'm asking this question, sensors
outputs :

Core 1: +58.0°C (high = +87.0°C, crit = +105.0°C)
Core 2: +57.0°C (high = +87.0°C, crit = +105.0°C)
Core 3: +55.0°C (high = +87.0°C, crit = +105.0°C)
radeon-pci-0100
Adapter: PCI adapter
temp1: +52.5°C
In order to "fix" this problem, I tried/did the following :
- I installed and configured
laptop-mode-tools
as suggested by the Arch community. - I installed
cpupower
and set it to work under thepowersave
governor (CPU Frequency Scaling). - I checked my BIOS for fan-related parameters, but there's none I can see.
- I tried to work with Intel's graphics instead of using my AMD card, but I'm not even sure this worked (any way I could check it?)
- I tried to use
fancontrol
andpwmconfig
but apparently, there's not pwm-capable modules loaded. I couldn't succesfully loadit87
. - I've set the ATI power profile to
low
. - I've set the ATI power method to
profile
.
After that, I decided to try other distributions, in case there would be a problem specific to Arch.
- OpenSUSE shows the same behaviour.
- Back to Ubuntu, same, even if I used it when dual-booting with W7 !
Having tried most of the things I know when it comes to high temperatures, I have to admit I've now run out of ideas... Is there anything I've missed, something I should try on my machine ? Something I've lost when I shreded my hard drive ?
