Question power supply fan position

For my computer, is the big PSU fan supposes to face up or down. Also for the four pairs of screws and the distance between the two top and bottem two, which one is should be closer. If there isn't a general direction, what are the positions and distances of your PSU's? Thanks for you time. I greatly appreciate it.

The fan should face down.

A great mod is to make a blowhole for the big fan in the top of your case and flip the PSU. That way it sucks in cooler outside air, keeping the PSU cooler.

With out moding your case it will only fit facing down. But if you do mod it then be sure to add exhaust fans to your case because the psu fan act's as the main exhaust fan for your system and if you make a blow hole there will be no exhaust fan.

it suck's the hot air out of the case into the psu and blow's it out the vented back, all psu's are the main exhaust for your case. stock computers its the only one.

The psu's that have only one fan in the back are still blowing out!! they suck air from within the case threw the vents on the inside, thus exhausting the air from the case. simple!
