Is it possible to control the chassis fan on a Dell Inspiron 530? That
fan appears to always run at full speed; would like to quiet it down when
system isn't busy.
Running Debian with a 3.2.0 kernel but willing to try anything for a
quieter system.
fancontrol/pwmconfig work for CPU fans with acpi_enforce_resources=lax
boot option, but I can't find any documentation as to how (if at all) to
control CPu fan. There is also nothing applicable in BIOS (using latest
release -- 2/24/09 1.0.18).
i8k kernel module won't load without force; but with force, none of the
fan/temperature parameters are correct in /proc/i8k (only the BIOS
version).

Note /sys/devices/virtual/thermal/thermal_zone0/temp always reports 40000
(I assume this is the temp1 above).
/sys/devices/virtual/thermal shows cooling_device{0,1,2,3,4} and
thermal_zone0.
Changing cpufreq governor settings makes no difference.
