A1 mini - Silent, less vibrarion

Hi all. I've switched over to Bambu and am loving the reliability.

I don't particularly care about speed, and don't print a huge number of items. I just want it to work away unobtrusively in the corner.

I've played with some settings with little success. 'Silent mode' does not seem to change anything. I can feel it shaking the sofa I am sitting on like an earthquake and the cooling fan is extremely obnoxious. I tried to reduce cooling fan % (both in the app, and on the machine) during printing, but it quickly reverts back to the original value. Am I doing something wrong?

What settings should I be looking at in the slicer? Changing print speed makes normal layers quieter, but the acceleration, print speeds and fan speeds for supports are as normal.

Many thanks
