Got a PPM the last few days and been trying it out. I notice when I run on battery the fan is quiet particularly when run on Eco mode, yet if it is run while plugged in the fan noise is unbearable it run so loud. I read somewhere this is due to an extra lamp or something to that effect when plugged in.
Is there anyway to emulate the battery mode even if plugged in?
Have you updated the firmware? I think there were changes to the fan behavior in one of the updates. If I am not mistaken, fan speed is now dynamic unlike before where it’s set per mode.
