Do you know where to get this fan for replacement? Having trouble finding a parts list.

Small fan is GB1245PKVX-8, large fan is KDE1285PTV1

I am trying to determine if the fan works or not. Should the fan come on when there is no bulb in the projector? I removed the bulb when it burned up and I am not sure whether it was due to a failed fan or simply the bulb.
