IIUC the problem is not the fan, but the power management.
I.e. the fan will turn itself off if the temperature goes down
sufficiently, but that doesn't happen under GNU/Linux because the power
management is not as good as under Windows.

I don't have a T410 so maybe I'm talking about something unrelated, but
at least my T60's power consumption when idle has never gone nearly as
low under GNU/Linux (lowest ever for me: 12.3W) as under Windows
(lowest below 10W; only time I booted Windows on this machine).
