If it works as expected and no system instability occurs (there's only a small risk) then make these changes permanent by adding them to the GRUB_CMDLINE_LINUX variable /etc/default/grub ( source) At the grub menu press e and navigate to the line with splash (or nosplash) and insert pcie_aspm=force and i915.i915_enable_rc6=1 I have never tried on a non-DELL or non-ThinkPad laptop so try them at your own risk.Ī couple of other things you could try are While the worst case scenario is probably that they just won't work, for all I know they could cause the machine to explode and rip a hole in space time. No idea if it will work on an ASUS but it might be worth a try.ĭISCLAIMER: I have only used these with their respective laptop brands. There is a very nice utility called ' Simple ThinkPad Fan Control' which allows you to fine tune the trigger temperatures that change the fan's speed. This package will install certain modules and programs that are specific for Dell fans and is very likely not to work on an ASUS. There are some laptop brand-specific utilities are for Dell and ThinkPads but they might work for your ASUS: If I recall correctly, the Jupiter applet can control the fans but I haven't used it in a while. To activate it do sudo echo ondemand > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor Ideally, this will be completely transparent for you, you machine will simply work as fast as necessary for the current tasks. With ondemand, your CPU will only run at its highest speed when necessary. Conservative acts like the ondemand but increases frequency step by step.Ondemand scales the CPU frequencies according to the CPU usage (as do the userspace frequency scaling.Userspace exports the available frequency information to the user level (through the /sys file system)Īnd permits user-space control of the CPU frequency.Powersave keeps the CPU at the lowest possible frequency.Performance keeps the CPU at the highest possible frequency.The governor controls CPU frequency scaling.

It might be set to 'Performance' or similar which means it will always run at full speed.Īlso make sure you have a reasonable CPU scaling governor. First of all check the BIOS, some laptops have settings that allow you to control the fan there.
