I know my following question is not very scientific due to the nature of equipment used (iphone 12 pro), but i am curious if my unit differs from others and are everyone getting same massive change in fan noise when switching from low to high. Basically i can hear my pj running in high lamp mode across the apartment - easily (like over 10m away.
Here are a few measurements i took 3-6cm from the front exhaust using DecibelX app:
Lamp in Low mode, AVG 44db. This is an ok level for me personally.

Lamp in High mode, AVG 51.4Db.
This is over a 7db increase when changing to high, this means that projector becomes 2-3 times louder. This is so loud that in normal movie viewing sound is audible unless its an action scene and volume is up.

Do we have other owners of this projector in the forum who could try the same? Is this level of increase in noise really normal? This is quite an expensive (and huge) unit, i would expect better noise control, it was surprising that previous Sony was so much better in this regard.
Thanks
