In contest situation, you might not get it as hot as a long winded rag
chew transmission.  I don't contest, but I've gotten it hot enough that
it hits the high speed fan mode.

I would expect a slight sag when it gets hot, but would head off the
heat by going into the menu and changing the fan control from NORM to 3
or 4 (depending on your condx) to keep higher minimum fan speed.  That
fan is a screamer when it hits 70C.  Don't forget to take it back to
NORM when the contest is over.  That will save a lot of wear and tear on
the fan.
