I'd have a fresh install of Ubuntu with tlp configured and using acpi_call to keep 7670M turned off.

I was a short time arch user and with openbox and firefox it was about 60 to 70 degrees; wanted to turn to a stable release just for this reason.

    Adapter: Virtual device
    temp1:        +50.0°C  

    Adapter: PCI adapter
    temp1:       -128.0°C  

    Adapter: ISA adapter
    Physical id 0:  +56.0°C  (high = +87.0°C, crit = +105.0°C)
    Core 0:         +54.0°C  (high = +87.0°C, crit = +105.0°C)
    Core 1:         +55.0°C  (high = +87.0°C, crit = +105.0°C)

The temperature is not seriously high yet can be lower.

Any suggestions?


Surfing temps with one tab firefox:

    Adapter: Virtual device
    temp1:        +58.0°C  

    Adapter: ISA adapter
    Physical id 0:  +57.0°C  (high = +87.0°C, crit = +105.0°C)
    Core 0:         +55.0°C  (high = +87.0°C, crit = +105.0°C)
    Core 1:         +58.0°C  (high = +87.0°C, crit = +105.0°C)

Edit 2: Using a simple linux game get highten it to 70.

Good questions, but can you separate them into separate question entries? Too hard to answer in this form. – belacqua Jun 26 '13 at 23:15
I just did, thanks. – user170534 Jun 26 '13 at 23:19
Install xfce instead of unity to disable the heavy use of compositing and your temp will drop. – RobotHumans Jun 27 '13 at 0:27
56 C is normal...what you can do is to use powersave on ac/bat with TLP, use indicator-cpufreq to change cpu frequency when you needed...use VA API if you are watching videos ( highly recommend )… – Qasim Jun 27 '13 at 0:28
Agreed, this is a normal temp. You can set up CPU throttling that will keep you CPU as a set temp, maybe worth a look Cool your CPU temperature with frequency throttling – BiggJJ Jun 27 '13 at 0:40
  1. Run the command sudo cp /etc/default/grub /etc/default/grub.backup
  2. Run the command gksudo gedit /etc/default/grub
  3. Make sure you do not see noacpi (set it to acpi or delete it, depending on where it is), pci=noacpi (set it to pci=acpi), or acpi=off (set it to acpi=on)
  4. Reboot and see if it helps.

Basically, you set Ubuntu to use acpi to control the hardware, which generally fixes overheating. If your computer does not boot, revert /etc/default/grub to /etc/default/grub.backup.

there is no acpi in grub.cfg and I think tlp handles what you mean by control, but since I use acpi call that however, I think is on too. – user170534 Jun 30 '13 at 6:07
