https://bugzilla.redhat.com/show_bug.cgi?id=531916 describes a system with a _PSC method for the fan that always returns "on". There's no benefit in us always requesting the state of the fan when performing transitions - we want to do everything we can to ensure that the fan turns on when it should do, not risk hardware damage by believing the hardware when it tells us the fan is already on. Given that the Leading Other OS(tm) works fine on this machine, it seems likely that it behaves in much this way.
