Which side should the intake fan be?

Solution
Front, side and bottom fans are intake. Top and rear fans are exhaust. There should never be a top fan that's configured as an intake unless you have a radiator installed in a top configuration for water cooling and choose to use it in an intake configuration.

Heat rises, so you want to expel that heat, not push it back down towards your comonents.

Being above the CPU cooler heatsink, in an exhaust configuration, would be the recommended method if you have two or more fan locations at the top of the case but only one fan. Do not use it as an intake or you are going to create air turbulence that disrupts the flow and exchange of heated air through the case.
