[Elecraft] KPA100 heat sink temp

[Lee Buller]

I have been running CW on the KPA100 tonight on 40 around 25 to 30 
wpm.  The heat sink heats up pretty fast, but doesn't get HOT but gets 
warm.  I am not sure as to when the fan kicks on so I have it on all the 
time on HI.  How hot can the heat sink get before things go 
haywire?  According the manual, the whole thing will go off line if it gets 
to hot.  What are the specs and how hot over time does it get?

Anyone have any contest experience with the KPA100 on CW?
