High System Temperature

donniezazen · 2011-09-08 19:10:02

Hi,

I am running Arch Linux with XFCE4. My system is really high on temperature which forces fan to run 24X7 and hence poor battery life. I usually get 45-50 degree Celsius on windows but i am getting around 65 with just browser open on Arch. I have configured TLP, Powertop (would be nice if it could permanently save its recommendation), thinkfan and power regression solution suggested by phoronix. I have a Thinkpad T420.

I might be able to work with you a little on this since I have the same machine. Also, I'm currently running xfce.

What processor and video chip do you have? Are you using a spinning-disk hard drive or an SSD?

Also, how do you have your sensors configured?

Thanks for replying. I have Thinkpad T420i (4177CTO) with i7 Dual Core 2620M 2.7 Ghz Intel processor, 8 GB RAM, Intel HD 3000 (integrated) and Nvidia NVS 4200 1 Ghz GPU, and 500 GB 7200 RPM spinning-disk hard drive.

I mostly tried these two webpages to setup thinkfan/sensors.

http://thinkpad-wiki.org/Thinkfan#Keine … nel_2.6.38
http://ubuntuforums.org/showpost.php?p= … ostcount=3

Installed lm_sensors and ran sensor-detect to locate sensors using command find /sys/devices -type f -name "temp*_input"
I have thinkpad_acpi, tp_smapi, coretemp in modules section of rc.conf and thinkfan in daemons.
Installed thinkfan and added options thinkpad_acpi fan_control=1 to /etc/modprobe.d/modprobe.d.conf and created /etc/defualt/thinkfan with START=yes

I have TLP installed and added it to daemons.

I came from Ubuntu due to heat problems. I think this laptop suffers from power regression issues. I updates to grub2 and added pcie_aspm=force to /etc/default/grub but i couldn't do sudo update-grub but pcie_aspm=force seems to have replicated itself to kernel line of grub.cfg

I have ran Powertop. I wish if i could make it permanent.

Thanks.

I was having a problem with high temperatures as well, even after installing and configuring cpufrequtils and laptop-mode-tools. What finally brought it down in a significant way was this:

I hope it works for you.

Thanks i915.i915_enable_rc6=1 seems to have done the job. It brought down the temp to around 55 degrees and then i disabled Nvidia Card which seems to suck power even when not in use. My temp is now around 51-52 and fan is on level 1 or 2 instead of 4-5. This is going to get me big boost. Thanks.

What driver are you using for Nvidia? Perhaps switching to the other driver will help with your issue.

I have not installed nvidia drivers yet. I am using xf86-video-intel for power saving integrated GPU.
