Hi Jean

Thank you for clarification. But is it possible that when I/O ports is
controlled by motherboard, the kernels can still "read" the
information from the I/O ports rather than read and write data to I/O
ports? I think in this case, at least, I can monitor my fan speed
without really controlling the ports, and I think it's still safe.


Best Wishes,
