I believe what you want to do is possible. You will need to figure out
if it really is possible to run a guest OS and grant it access to the
non-virtualized hardware. Then you can compile a guest OS with hwmon
support and monitor the fan speeds. That kind of question is something
I cannot answer for you. I suggest you join the gentoo forums and ask
there (http://forums.gentoo.org) because they are responsive and
helpful. You will still need to be persistent and patient (and as
clear as possible). If you know of another forum you would rather use,
by all means go ahead.

>From my understanding, VMware is very capable and should be able to
pass through I/O accesses to the "raw hardware". The overhead will be
significant, but hwmon is not latency or bandwidth limited, so you
should be fine.

Perhaps, when you find an answer, if you would post a summary here,
that would be appreciated.

Good luck,
