North/South vs East/West

post #1 of 4
Thread Starter 
What bits I know about cooling makes north/south seem like it should be slightly better and in an article i read they said it was much better :/.. East/West is the more common way, but anyways which is better?
Current fan setup: side panel bottom is intake, bottom intake, front fan is intake, the fan right after hdds bays is well sucking air through the bays. rear is exhaust and 2x top exhaust.

I'd recommend you put it horizontal/pointing the airflow towards your rear exhaust. I'm not sure if it'd make a big difference but I feel if you point the exhaust towards the top you might draw some of the warm air coming up from your graphics card and it could increase your temperatures.

Not 100% though.

According to BMR with the megahalems having it in north/south ended up with a 3 degree increase.
Also what size fans can i fit into 2 5.25" drive bays?

Strictly speaking, hot air rises so north/south should be better from a thermal perspective. However, if the fan on your heatsink is sleeve bearing, then it will last longer in a east/west orientation (north/south puts strain on the sleeve bearings). Also, I chose my direction to be east/west because my cooler is HDT and i want as many heatpipes as possible to cross across the long side of my cpu core. Thus there are many factors in choosing your direction.
