Welcome to the world of HP :)!
I bought an nx6110 last year. After an update some time ago my fans
stopped working at all and the thermal protection kicked in at 90
degrees C.
I searched the HP support forums and found a lot of people with
similar problems - erratic fan behavior. What I gathered from there
is that the reason is buggy acpi implementation in the BIOS, even the
newest version.
There are two entries in the kernel bugzilla you might find useful,
with patches attached:

Best regards,
