Here is a copy of a posting I made on 20090312:
Earlier today, I remarked that one of my K3's was running
warm in the NAQP RTTY after an extended number of RTTY CQ's.
Tonight I did a little experiment - key down at 100 watts
for four minutes while noting PA Temp and fan speed. It
turns out that there really is no problem. 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.
