I did an experiment on my two K3's - key down at 100 watts
for four minutes while noting PA Temp and fan speed. Both K3's 
behaved
identically and both leveled off at PA Temp = 64C after
about 3 minutes. For the record, here are the results (best
viewed with Courier font):

Time   Temp  Fan
0:00    26C   0
0:26    37    1
0:44    41    2
1:19    50    3
1:45    55    4
2:40    60    4
2:50    62    4
3:15    64    4
4:00    64    4

Room temp was 77F.

According to the manual, the PA is set to drop into bypass at
84C, so it didn't even come close.
