Does anybody know if thinkpad-acpi's fan control works properly on these X1xx models? I did a "cat /proc/acpi/ibm/fan"
and it reported the following:
It doesn't seem like 600RPM is a lot at all, especially with all that heat.
Many thanks in advance, it's a great laptop/netbook otherwise. Idle temperatures on Windows 7 don't seem nearly as bad, so I'm wondering whether this is a Linux problem, and whether there is a solution.

Same Thinkpad here, with same problem on Linux. It seems that some other guys reported the problem and exposed solutions through the web. A quick search gives some usefull links, among others:

Running Debian testing in my X121e, as recommanded in these articles, I put options that GRUB passes to the kernel, in /etc/default/grub file:
Code: Select all
GRUB_CMDLINE_LINUX_DEFAULT="quiet pcie_aspm=force i915.i915_enable_rc6=1 i915.i915_enable_fbc=1 i915.lvds_downclock=1"
Now, my laptop is around 10°C lower than before!
Hope it helps...
