Hi everyone,

i just finished to install Gentoo on my macbook pro (late 2011).
Everything went well, and now i am ready to enjoy Gentoo once again.

Nonetheless, i noticed that the fan speed was very high.

Therefore, using "sensors" and "gkrellm", i checked the CPU temperature.

Sensors shows the CPU's temperature critically high: 96/98C (for each core) (i was not running particular application or compiling/emerging).

Now, i'm back to osx (the CPU temp is around 57C) but i would really like to fix this problem.

Any ideas?

Please let me know if you need any information about my kernel configuration or something else.

Thank you in advance.

Michele

Sandybridge? Ensure that the intel p-state driver is being used, not the acpi driver for cpu stepping. There is a noticeable difference in temperature.
