Amiga 4000 Desktop Fan?

Ok whats the deal with the 4000.  The Fan should blow air in or out?  I have my 4000 open today doing some troubleshooting (iBrowse crashes, maybe due to 3128 installed) and think my fan is blowing air into the drive cage.  Hard to tell.  I have it fully loaded see my sig.  With a Sony CDRW drive too.  Is the fan on the PS at the back near the CDROM?  Or at the back of the 4000?

OK mine blows out.  So thats good.

Well I am trying to find out what caused my iBrowse to crash all the time.  Mostly on eBay though.  BUT on my 3000 060 sys it works fine all day long!  So it must be my 4000.  I had issues with my DKB 3128 before so I removed it and i still get crashes, but not as often.  I am stumped.
