Just a note regarding moderately elevated chain/chip temps.

My chain 3 chip temp was consistently about 8deg higher than 1 and 2, (often edging over 80deg).

Last time I shutdown I took the opportunity to move chain 3 into the chain 2 position, the logic being there is more airflow in the centerline.

This seems to have WORKED.  While still a nudge higher than the other two, it behaves much better relatively.  Or at least it's sensor is happy.  ;-)

Cheers,
