Projector fan very audible

[atds99]

Had a teacher ask me to look at a projector that is quite loud, I proceeded to clean the filters etc but still as loud any suggestions??

 

Thanks

Someone hasn't turned on 'High Altitude Mode' in the settings have they? That often increases the fan speed to compensate for the lesser cooling effects of thinner air at high altitudes.

Most of these fans are pretty standard things. It may well be possible to replace it, if the bearings are shot.
