  1. Hi all, Has anyone ever upgraded the radial fans of an Ultimaker 3? I have to slow down my print to about 20 mm/s to make sure the overhangs don't curl up. I figured that if I upgrade the radial fans so they cool better, I can print faster and still cool sufficiently. Yet, I don't know if there are fans that fit in the print head, cool better and won't draw too much current (assuming this could be an issue). Does anyone have any info for me? A quick search on Google, Reddit or this forum didn't give any results. Thanks!
