Hi Folks,

Which way is the air flow supposed to be through the fans on the K3?  Mine 
blows out, pulling air in from the slots in the top above the KPA3.  (My K2 
blows in.)  The manual doesn't seem real clear on which way to install them in 
the K3.  

My K3 is nearing eight months old and doesn't seem to have a major cooling 
problem.  But, I do some heavy RTTY contesting and I've occasionally seen the 
PA temp at over 60 degrees centigrade.  I'm considering adding a fan on half 
inch stand offs from the bottom of the shelf above the radio to blow through 
the slots in the top of the K3.  Will this disturb normal airflow around other 
components possibly causing them to overheat?

In the past I installed an external fan on two off-shore radios and it seemed 
to improve cooling.  I want to be sure I have the fans installed correctly and 
there would not be other problems before proceeding.

Thanks everyone.
