one suggestion...

hey guys, i was just wondering, why don't we use the fan on the psu's as intake rather than exhaust?

since we're all running (mostly) passive cooling with minimal air flow, our case temperature should be pretty high, most certainly higher than the normal outside temperatures.

we can duct the hot air away from the psu to either one of the 5 1/2 bays or to some other holes.

what do you guys think? wouldn't this significantly lower the psu temperature? thus increasing its reliability and lifespan?

are u talking about reversing the fan in the back of the PSU?
This would probably keep the PSU cooler but it would mean that the heat from the PSU would also enter the case (bad) or if u ducted it it would mean that the internal air wouldn't have a path to go.... A typical computer case has a reversed S airflow pattern where the air comes in the front and ends up getting exhausted out of the back at the top out of the PSU fan and maybe out of a exhaust fan if u have one

If you wanted to do that , you could just make your duct to the front 5 1/4" bays and leave the fan as an exhaust fan? Would be the same as your suggestion i think. Then you would need a separate exhaust fan as well tho.

It is something i thought about doing, but dont really need to now

u know what u could try, is positive case pressure and have the power supply with no fan at all being the only exaust

if u're going to try it this way, make sure there's no other big gaping holes in the case as well... all computer cases are very leaky so the air will go out everywhere not just out of the PSU exhaust.
