Does anyone have suggestions for a fan that I can hook up to the cooling
vents in my flight deck? It doesn't need to generate a strong rush of
air...just enough to circulate the air a little.

I am looking for something fairly quiet and not very big. It could be AC or
DC, 12v or 120v. Thinking about an automotive centrifugal fan, but not
sure what model to look for.

Any leads would be most appreciated.
