Apparently not all K3s are created equal, thermally speaking.
On my K3, it takes
-on and the PA is barely warm. If you
can out-design N6KR, I'd be amazed.

Hello,
I am currently in the process of upgrading the fans for the KPA3 100 Watt
Amplifier module because the heatsink temperature gets too high for my
liking. I am upgrading both fans to a fan with higher CFM output. Last night
I hooked both fans up to the KPAIO module to test and see if they
Elecraft has the temperature management aspects covered.

If it ain't broke - don't fix it. The fans on the K3 are fine. If your
K3 is getting hot, check the original fans to be sure they weren't blocked
by a screw or something. There is a fan-check procedure outlined in the
manual somewhere (menu item?). You can also read the actual temp on

run at less than speed 2, but will speed up at the
appropriate temp as the PA warms up.

I don't understand why you are looking to upgrade over the std spec -
surely elecraft have considered all the possibilities of ambient temp
to run in - unless of course you are operation in an oven?

I wonder if elecraft actually does thermal and vibrational stress
analysis, I've always been curious what the natural frequency of my K2
is, as well as what the rise from board to chassis is in a 71C
environment :)
