InFocus LP435Z Secondary Fan Replacement

Введение

The small, secondary fan sits just behind the vents in the grill next to the lens in the front of the projector. It draws air over the light focusing area that can get quite hot due to the lamp, and also aids in drawing more airflow into the projector for the main fan to circulate.
