So I'm looking at designing a new part cooling for my hotend. But looking at this, it started me wonder. When designing a part cooling piece, what's more important? Air Pressure at the nozzle? Air Flow? Air Volume? I know the whole argument between a fan and a blower, and I'm already planning to use a blower. But I'm conflicted if I need to narrow the exit down, open the area on the nozzle up, hit it from multiple sides and this is what started me thinking what's more important in terms of Air Flow, Air Pressure, Air Volume, etc...
I'm not worried about the nozzle temp ad it's under a silicon sock, and even if the temp drops 1-2 degrees with the part cooling the Duet PID compensates pretty quickly.
