Chris, you could try to test and see if applesmc is the cause. Try
preventing applesmc from loading (add 'blacklist applesmc' to
/etc/modprobe.d/blacklist.conf), and see if your fans still stay at
2000 RPM under CPU-heavy workloads. Of course, you'll have to just
listen to find out if the fans spin up instead of checking sysfs, but
this will at least help debug the situation.
After booting, verify it wasn't for some reason in the initramfs by
running:
lsmod | grep applesmc
Check that it's not loaded (should not see anything listed).
Jon.
