Intake vs exhaust

[r00tb33r]

Wondering why new cases that are vented on the front all choose to pull air in, rather than push hot air out?  Where intake fans outnumber exhaust fans.

 

Wouldn't removing hot air from the box be a higher priority than mixing it inside with air coming in?

 

Negative pressure vs positive pressure inside?

 

Did anyone experiment with a front exhaust and rear intake (possibly no rear fan but just a grill)?

 

(Please no suggestive humor )

If there's no air in the case in the first place, there's no way you can move it

Positive all the way

Ye but if you do this with rgb fans it'll both look worse and with less intake, may perform worse

I think it will pull air from every gap and crack in the case, and that could mean pulling hot air from places where the usual exhaust path usually trapped hot air, such as behind the motherboard or below the GPU.  It would pull unfiltered air and dust, but don't see that as an immediate concern.

I literally cut fan LEDs off if I can't turn them off.

You can try it yourself. Are you using an aio or an air cooler? I would put the exhaust as intake. Turn the top two fans as intake and turn the air cooler around as exhaust to front

Alternatively, a reason for doing positive pressure to the left is just cuz thats how pc cases are laid out and that's just been the standard

Let's say the case is closed at the top and has no top fans.

 

I use an air cooler and would flip the fans around to the other side of the radiator so it would blow toward the exhaust at the front.

 

Back in the day PC cases didn't have fans on the front, just exhaust fans on the back.  I'm thinking they likewise were focused on removing hot air, rather than forcing it in.

Usually front is supposed to take air in, but it depends on use case

I do use rear/top intake and front exhaust, because my rig is in a mostly closed cabinet  under my desk (pic)

I started with standard layout front intake/top rear outtake but the hot air clumped around the desk area, temps increased and it was uncomfortable

New setup really works well, temps are fine and no "sauna" zone anymore

Looks cool, though.  Great talking piece for the people who like showing off their PC.
