I noticed some things with the KPA100 that I wasn't expecting. Are
these normal?
1. Power output fluctuated during a single CW TX session. I'll see the
PO indicator on the K2 go up & down by 1 LED on a frequent basis (maybe
switching every few seconds). Thinking that I was right on the edge of
an LED transition or something, I changed the power output level. The
behavior continued at the new higher power level. I also see the output
power on my outboard power meter change. The changes appear to be
fairly small, maybe 10 watts at the 100 watt level. Is this normal?
Yes, but there's a mod available to reduce the variation. See

and <http://www.elecraft.com/Apps/Power_Control_Mod.html>
2. Fan came on. My shack is a chilly 62 degrees F. I set the temp in
the K2 per the instructions. During a CW QSO, the fan came on about 1/2
way through my TX session and stayed on for about 1/2 of the other guy's
TX session. Power out was 100 watts, SWR is flat enough to not deflect
the REV meter on the Palstar. The heat sink did feel warmer than the
room but no way I'd say it was hot. Is this all normal or is there an
issue?
Yes, I think so. See what others say.
