Any chance I've missed "Power On Line" setting, that powers on the meter after power loss/line on? I use it with SDS1104. All gear is connected to remote power plug. It's the only device that doesn't "Wake up" is the SDM.

Did you try a Noctua fan, and was it effective?

Just a rhetorical reply here.
In my lab I usually have at least 3 computers, a power supply, a function generator, and a benchtop DMM and sometimes multiples of each of those along with a DC load and some other equipment on with the scope(s) (I have 3 workstations) so I have never really noticed how noisy my SDS1104X-E is. So I just compared it with the other two scopes in there and it is the quietest of the lot.
It makes about the same noise as the little Lenovo X230 I have at my soldering station when its fan is on. From my perspective, it's pretty quiet.

Our customer did with a Noctua with very similar spec to OEM without gaining any significant difference.
Investigating further for him I cut the metal fan grille from mine and this too didn't gain a significant difference.
IMO the only way to address this is to undervolt or change the fan to one of a different spec, however then throw the datasheet accuracy spec out the window.

Is there something seriously wrong with your notebook? I wouldn't call the SDS1104X-E noisy by test equipment standards, but those standards are pretty low. I have an X220 beside the scope right now, and the scope completely swamps the notebook.
Most of the electronics work I do these days is fairly low power, and pretty much silent. When everything I worked on was high power and really loud I wouldn't have noticed a scope like this at all.
