/*I have chosen to put a Noctua helper fan on the inlet pushing air
through it has helped, This fan is powered on from the k3 12 volt out it
comes on with the radio runs all the time, my room temp is 67 degrees f
the amp is idling at 24c I can usually get a reasonable cw rag chew over
in before the fan gets to launch speed. This is not a total fix but does
help. This fan sits on the soft rubber feet that you pull into
positioning through holes in the 4 corners.
Here is a link to this fan these are very good at quietly moving a lot
of air I have a pair on the k3 as well.

Interesting reading is the development of the design venture, ribs,
blade shape.....

For the NAQP cw party this past weekend, I ran low power. Rather than
'stress' the K3s with 100W, I chose to run 6W thru KPA500, giving me 100w.
During a one hour run period, 125+ Qs on 15m, I noticed the KPA500 temp
at 51C which surprised me. Idle temp in the shack is generally around 33
to 35C. I expected much lower temp at 100w output.
Why the higher temp and is it not related to power out?
