It usually does not matter where the fan is located in a power supply. Modern atx power supplies exhaust air out the back of a pc case. In your case warm air should be exhausted through the perforated mesh on the back of the psu.

bernie, the current trend is toward side mounted fans, because you can use a larger fan. A larger fan, moving the same amount of air as a smaller fan, rotates more slowly, making it more quiet.

As Johnny said, regardless of rotation, the fan will exhaust air out the back of the PSU.
