[Elecraft] Cooling fans

Kevin -

It has been my experience that blowing air onto a heat sink is usually 
more effective than "sucking"  air.   If the heat sink is carefully 
shrouded and the incoming airflow is properly controlled, then either 
method is supposed to be effective.  However, for uncontrolled or casual 
situations where you are simply placing the fan on or near the heat sink 
to be cooled, blowing (hopefully cooler) air onto the heat sink fins is 
much more effective in lowering the temperature of the heat sink.   The 
reason for this is that the outlet of a fan has a well defined airflow 
that can be easily directed to where it is needed, whereas the inlet 
side of the fan will gather air from wherever it can, some or even most 
of which may not be from the heat sink.  Good luck in the contest.
