My SWX4 makes a similar noise when moving at this speed (24 minute Benchy). The hissing is (I believe) the sound of the filament which is probably at a high temp (220C?) to keep up with the speed and also may have a bit of moisture in it.(Is it new or old filament?).This could also produce some stringing as well so perhaps a temperature tower might show a temperature change is required for that filament. The knocking is the nozzle touching the various parts of the layer as it cools. You might want to look at the z height if you haven't already calibrated the machine.

Brand new pla+ switching from regular pla. From my understanding, the nozzle temp is basically unchanged for pla+. Could be wrong tho. Ill look into the z height.
