Some cheap Chinese MK8 extruders seem to have too short a PTFE tube inside the throat pipe (between feeder and nozzle). This was the case with mine, resulting in the tube moving downwards over time, leaving too much space between feeder and PTFE tube, where filament could curl up and block. My blocking problems were gone when I simply inserted a longer end of PTFE tube.
205° is well within reasonable bounds for PLA, and should cause jams or blockages with correctly configured hotend.
