fan - no fan (2 replies)

I am fairly new to 3d printing and so far have had fairly good luck as the quality of my prints keeps improving. I have a prusa using budaschnozzle with no fan. I have been thinking that the fan might help me some how but really don't know "with what". I guess if it's not broke, it might not need fixing, but since I don't know what a fan would do for me quality wise, I may not know if it needs fixing.

Can I get some opinions about fan/no fan?
