In the picture it looks like the fan is pointed toward the hobbed bolt.

Can you help me understand why it isn't pointed toward the extruded filament?

I mainly mounted the fan to give the cold-end some more cooling. I have a J Head nozzle Mk1 and it didn't seem useful to me to point it at the peek bit because of the good thermal insulation or the copper nozzle, the part that I want to be hot.

My fan is always on when printing and not used to change the nozzle temperature for different printing stages.
