Akasa Apache air dirrection confusion !!

[0neAnd0nly]

Which way should I mount the Akasa Apache fans to the cpu, I know which dirrection for intake arrows but not the right and left arrows depenidn which way I rota the fan, Should I have an arrow pointing to the roof of case, side vent or toward the botton intake fan ?

Is it an arrow to show where air flow is coming from or where a i should direct the fan to intake the air flow (from the dirrection) I that makes sense haha

Thanks guys, I've had them pointing to the top fan for now, doubt it will make much difference, build should be finished in a couple of hours
