Constant hum from the inside of my H2D

This one?

H2C PSU fan always running in standby

Hi folks, for the first two weeks my printer was pretty much running 24/7. Now, as the first excitement fades, I was wondering where the noise comes from in standby. I figured out it was the PSU fan (in standby, hours after a print) and opened a ticket. I was assured that it is normal that the fan -even in standby- is constantly on. I find this quite unsettling as no of my other printers do this. So - H2C users: is your fan always on?
