Avoid clogging

I have an ender 3 v3 ke. When I print with pla the printer always clogg, the same don’t happen with petg. I learned how to unclog the printer, but the printer clogg again and again. The least calibration I try to make is the temperature Tower but the nozzle clogged in the middle of print with 225 graus. Them I started again with 220 graus e the tower broke in the middle of print. I try two different brands of filament, one is from creality, both clogg. I would like to know why this happen and what I can do to avoid this.

The most common reason is the Hot end fan. look if is working fine, clean it and reseat the connector.
