Ventilation noise

Nothing disturbs the enjoyment of HomeCinema more than a droning projector fan. That's why it is important to take the noise production of the standard integrated fan into consideration. The noise level is given in dB. Devices that have a noise level below 40 dB are recommended

Should the ventilator noise lie even lower than 32 dB, then these count as "super quiet ".

The side-tone of the fan can, for example, by making use of the technology in the devices that feature the ECO-Mode, be drastically reduced. With this mode, the lamp brightness is also reduced. Due to the lower brightness, less heat is produced.
This has an immediate effect on the fan as it needn't transport so much heat out of the device. The corresponding noise produced is lower.
