Normally rear-mounted case fans pull air out of the chassis, while any front or side fans pull air into the chassis (creating front->back airflow). If you set up the main fan to push in cooler air, then the PSU fan immediately exhausts much of that cooler air - so it will never reach the electronics.
You can easily check the orientation by simply putting your hand near the fan egress. I recommend keeping the fan orientation that you have now.
Changing the fan voids the hardware warranty, so I suggest postponing this change untill the warranty expires. The fan should be covered by the hardware warranty, so if it is failing you could also request an RMA.
