This is an oversight that made use of the trip-point-based fan managenent
on
cards that never expose those. This led the fan to stay at fan_min.

Fortunately, the emergency code would kick when the temperature would
reach
90°C.

Ben, can you merge this patch? It is kind of critical :s And it should be
CCed to stable too, without it, some kepler/maxwell get 0% fan power which
is kind of dangerous, even without reclocking!

Ping, this is really important :s

Not sure who picked it up, but it seems to be in the latest fixes batch [1].
