gkrellm first tries to get sensor data using lm_sensors, but can fall back
to reading values directly from the kernel.  It tries lm_sensors first because
that is more likely to have correct scaling factors for newer sensor chips.
If it is a newer chip gkrellm doesn't know about, gkrellm still tries to read the
data but scales data by some default values which may just be accidentally
right for your chip.  Or it can also get temperatures from the ACPI interface.

We can tell more about what gkrellm is doing and the possibility of getting
fan data if you get sensor debug info by running:

   gkrellm -d 0x80
