Some more information...
I have confirmed that the fan runs when the Jessie livecd is running,
but the fan doesn't run for amd64 or i386 installations. I've compared
syslog, daemon.log, and lsmod and found:
syslog: Both livecd and amd64 installation have these lines:
kernel: [ 0.020564] CPU0: Thermal monitoring enabled (TM1)
kernel: [ 0.943898] thermal LNXTHERM:00: registered as thermal_zone0
kernel: [ 0.943904] ACPI: Thermal Zone [TZ01] (50 C)
syslog: There is a slight difference in the following line:
livecd: kernel: [ 3.144083] acpi device:3a: registered as
cooling_device0
amd64: kernel: [ 8.712124] acpi device:3a: registered as
cooling_device2
lsmod has slight differences:
livecd: thermal 17343 0
thermal_sys 27122 3 video,thermal,processor
amd64: thermal 17559 0
thermal_sys 27642 3 video,thermal,processor
In daemon.log, the amd64 installation has the following lines (but they
may be the result of installing the sensors package,
which the livecd does not have):
May 2 08:36:48 amd64 sensors[492]: acpitz-virtual-0
May 2 08:36:48 amd64 sensors[492]: Adapter: Virtual device
May 2 08:36:48 amd64 sensors[492]: temp1: +0.0°C (crit =
+100.0°C)
May 2 08:36:48 amd64 sensors[492]: coretemp-isa-0000
May 2 08:36:48 amd64 sensors[492]: Adapter: ISA adapter
May 2 08:36:48 amd64 sensors[492]: Core 0: +25.0°C (high =
+100.0°C, crit = +100.0°C)
May 2 08:36:48 amd64 sensors[492]: Core 1: +26.0°C (high =
+100.0°C, crit = +100.0°C)
Any help would be greatly appreciated.

I have done a fresh install of Jessie on an old Acer laptop and the
fan never runs, so it overheats. Interestingly, the fan *does* run
while Jessie is being installed.
Has anyone had similar problems? Does anyone have suggestions on how
to diagnose this?
Thanks.
