Clogging / heat creep

Hello Everyone,

I wanted to ask if anyone else experiences clogging and heat creep during printing? I had this 3 times in a few weeks now and never ever with my other printer.
I print quite fast, but only PLA with ~225. Since this is an allmetal hotend rated to 300° i am very shocked that i had to disassemble the extruder (and almost another time) now to remove the molten plastic from the gears.
At my place the room temperature is around 30-ish deg C but that shouldnt be a problem…

Any thoughts?
