Those who know something about fluid dynamics can also tell you that if
the air flow is restricted, the fan speed will be a bit higher (for any
given KPA500 selected fan speed) - it is because the fan is not doing as
much work to move air.
Try an experiment with any fan - partially block the air
he overly protective caution in the manual. Maybe
we'll see a change soon.

I do a lot of meteor scatter on 6 meters, and I've tried the tuner both above
and below the amp.
I've found the KPA500 runs cooler with the KAT500 tuner below the amp.

I wouldn't put it on top. I can hear fan and air changes if I get within a half
inch of the intake slots with my hand at higher speeds. You can feel the air
