Update 14.04.2018: Don't print high temperatures(230˚-250) or bed higher than 65˚ without the fan blowing. After printing PETG(230˚ nozzle with 80˚ bed, and fan without blowing) i had the surprise that the PLA fan(melted and deformed a little bit. So if you print High temp filament, print the fan from PETG or ABS, or if you don't need fan for the material remove it.
