However, upon close inspection, I noticed huge amounts of fine dust

Using a brush I scrubbed away all the fine dust and ever since I have

 This is definitely a physics problem.
 I have a very powerful fan blowing air through those cooling vanes
and they will eventually become totally clogged.  Considering the
strong airflow, Why is this happening?
 I posted this question to sci.physics.
 My theory, which I believe to correct, is that the stationary
boundary layer that always develops when flowing air contacts
a surface is responsible.  The dust particles can easily settle
in the stagnant layer and then more will eventually settle on
the layer created above, etc.
 Other posters claimed that static electrical charge is responsible,
which I find to be nonsense as the cooling vanes are grounded.
  

I don't remember that post. In sci.physics you must be under an alias that I have kill filed :) Hehe :)
You have no idea how long that kill file list is. God forbid I lose it and have to construct it again.
The two views you mentioned seem to me could be one and the same thing.
