fan issues

YAY FIXED!

SIMPLE

append:

 acpi=force

to the grub boot options.

then:

typing that command and redirecting that output to the embedded control dump (ecdump) file will turn that fan on at it's maximum speed.

Notes

this simple script found here:http://www.thinkwiki.org/wiki/ACPI_fan_control_script and take care of any unnecessary end-user interaction with the fan control. other useful information can be found their as well, about controlling the fan.
