FoolControl – Phear the penguin » Blog Archive » Linux power regression + overheating problem on ThinkPad [fixed]: Much improved fan speed, in my case on a Thinkpad X220, by updating /etc/default/grub to:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pcie_aspm=force i915.i915_enable_rc6=1"

Not sure if it’s the PCIe ASPM or the Intel graphics change that makes the difference, but the fan runs much slower (and hence quieter) after a reboot.
