Side fans vs hotend tip off-center

Posted · Side fans vs hotend tip off-center

I wasn't sure if this issue was addressed, I know from my searches on this forums that people are often adding "tornado" concentrators on the fans. But the off-center issue wasn't mentionned (I think).

I happen to print in abs and when doing cylindrical parts with 100% infill, it's clear that the off-center fan at the right is not pushing enough air to the tip, because my parts are still extremly soft to the right and this creates some plastic burns when the plastic touches the hot tip for a long time (the warping of molten plastic is going toward the tip).

Is there an easy mod/relocating of the fans that could prevent this off-center air flow?
