If you do not have active ventilation on the top of your case (i.e. fans pulling upwards), then don't use the 90 degree rotation method. There will be no practical benefit (the 1-2C change is within margin of error called installation). In fact it might be better if the rear fan is sucking air out of your heatsink in this case.
I'm not sure how the Elite 430 is ventilated so the 90 degree method just might work for you.
Hope u say d3p diagram so gonna have 2 fans on top and 90 degree rotation soon
