It's possible to reduce the ambient fan noise by putting your projector into ECO mode. ECO mode will dim the projector solid-state illumination (SSI) to lower power consumption and extend the lamp life.
To learn how to put your projector in ECO mode, see the SSI Settings section on the Options page of the projector user manual.
If your projector model is NPSi-1, ensure that its firmware is version C07 or higher.
