All intake and no "dedicated" exhaust?! - Page 3

Hear Hear. Data beats theory every time.

 

OP, building a custom case means you can dispense with slot pillars -- those swatches of sheet metal between the back slots. You can build it with no rear grill, so the air can gently blow out the back. Or you can build it with no top grills -- or anything else you like.

 

I don't recommend positive pressure cases, but I do recommend positive flow cases.

Lol I may add a back grill or some 60mm fans but that's it. And the holes on the back are not going to change. They will be closed off unless being used and they are a tight fit against the gpu since the back panel is flat

dont have grills, and don't have tiny fans, thats pointless and may actually be worse just let your tower heat sink fans point towards your rear case hole cutout with no grill and let the exhaust itself.

I'm making the case, those options don't really work for me. Like I said il do 3 intake off the rad and 2 exhaust off the top and maybe the psu will help a bit.

Heat rises you need a form of exhaust no matter what. You don't wanna create negativity pressure in the case.

You guys make it seem like somebody's talking about putting intake fans on every possible opening rolleyes.gif

And "negative" pressure would be from more exhaust fans than intake.

ehume's thread regarding case airflow showed you don't need a dedicated case exhaust fan, you can use the fan from the back of a cpu cooler to blow it out, or if you have a rad you can just use the rad to blow out

its pretty logical that with open pci-e slots and other grill-type openings in most cases, and dedicated exhaust isnt required. But if you have air being pushed in from 5 different dirrections, poor air flow would be an understatement. just push the air in one general direction with 4 fans and exhaust the last
