I'm curious, do you know if all the gpu options draw the same amount of power? The 5300, 5500 4 gig, and 5500 8 gig?Even the i9 is very quiet when not doing much.
It makes noise under stress with the following
1. external monitor
2. High CPU Usage(atleast one core)
3. Rendering/Export video
that said the culprit is the discrete GPU in my use case i.e. it uses more than 18 watts even with nothing open. The CPU scales very well with load it goes from 65ish watts(with short bursts of near 100Watts) all the way down to under 1W(thats smartphone territory)
There might be some imperceptible 2db difference with a microphone measurement but it would be unpleasant either way in a quiet environment.
