Do I make the top fans Intake or Exhaust?

[Mirakledba]

My plan is to get a corsair obsidian 750D and add 2 AF140's red led at the top...and the rear and the 2 front intakes will be stock. Is this the best way to do it?


The Two FRONT 140's as intakes, the 2 top 140's as exhaust and the rear as exhaust...right? 😀

That is correct. As heat rises, it is more efficient to have a top exhaust fan.

On mine case HAF 922 , top fans are exhaust, i think that is the logic , front intake, top and rear exhaust
