Transparency - not an engineer or techincal - I just know just enough to think I know the answer but need those who has experience to confirm it
I’d like to reduce the noise from the Glowforge installed fan. After testimonials of adding an inline fan, I’d like to do that. However, I have a space issue. I only have 9 inches from machine to window. That narrows my options of what fan to buy. I figured out that the CFM is probably 200.
The only one in the forums that I know works is the VIVOHOME 4 Inch 195 CFM Model and I’m sure I can make that one work if I line up my glowforge vent with my window port. But it’s bulky and will limit me reaching the window lever, and I will need to remake my plexiglass port. This is enough inconvience to ask the question of a shorter, lower CFM fan like this VIVOSUN 4 inch Inline Duct Booster Fan 100 CFM
I realized that that the shorter narrow inline fans has smaller CFM which I assume it’s due to the blade size but this will give me way more flexibility back there.
Question: Since the distance to window is short, will less CFM be doable? Or that CFM is mandory to suck the air inside the machine while it’s running? If it has to be 200CFM, is the Vivosun model the best option or are there fans that has a shorter base, smaller diamitres but still able to push 200CFM?
