[Elecraft] K3 Cooling

[Tom W8JI]

I don't get why it needs to generate any papers or studies 
or anything.
Its a really easy experiment to do.  Transmit into a known 
load and plot
temperature rise vs time.  Do it under the same conditions 
and better
yet do each experiment several times and average results. 
Then all you
have to do install the fans in the direction that generated 
the best
performance.  I'd even be willing to bet that Elecraft did 
just this.  >>>

That tells us **nothing** about the temperature of other 
components in the radio. It only tells us about the PA at 
the point where temperature is being sensed.
