------- Comment #7 from [EMAIL PROTECTED] 2007-12-27 23:48 -------
I have access to an HP nx6325 and do not see this problem
running Linux-2.6.23.12.
Though I do not run Windows on the box, I use this system
primarily to test ACPI based fan control on Linux.
I have verified that the fan speed kicks in at the
temperatures prescribed by the BIOS -- and also
that the fan slows down at the thresholds prescribed
by the BIOS.
I generally do this by running
watch cat /proc/acpi/thermal_zone/TZ1/*
<setting not supported>
<polling disabled>
state: active[3]
temperature: 48 C
critical (S5): 105 C
passive: 95 C: tc1=1 tc2=2 tsp=100 devices=C000 C001
active[0]: 75 C: devices=C34F
active[1]: 65 C: devices=C350
active[2]: 55 C: devices=C351
active[3]: 40 C: devices=C352
and then add some load, say via
$ cat /dev/zero > /dev/null &
$ cat /dev/zero > /dev/null &
and blocking the vents with tape, unblocking them, killing the load etc
and watching the temperature change, the active state change,
and listening to the fan on changes between states.
