One of my H960's actually came to me with a fan

top. I have a few loose fans, and my other H960 has no fan so I'm getting
ready to install one of those condor fans in my H960. I am wondering if the
H960 fans at the top are supposed to pull air in, or push air out? I'm more
interested in how DEC actually shipped them rather than "it'll work either
way".
I checked my H960 and it's set to pull air in from the outside downward into
the rack. Of course I have no way of knowing if that's how it originally
was, or if some collector/scrap person put it in backwards themselves.
Anyone set me straight on this? I suspect that's how it's supposed to be
given the channel on top for an air filter of some type.
I'm in the early stages of work on a PDP-12, and found that one of the
two ceiling fans was disconnected - turns out it has a bad squeak; I
suspect they unhooked it so they didn't have to listen to it - and
discovered, to my surprise, that both fans are set to suck air downward.
So not a _definitive_ answer, but certainly another data point suggesting
yours is normal. :)
