This is interesting .I look at the same two psus. Fisrt I wanted to go with the fortron 530 because of all t he recommondations on this forum, but ther are two points to consider for me. I live in the desert so in summer the average temp during the day is 85F .If you read the following good thread
http://www.ocforums.com/showthread.p...hreadid=231559 you see, that it gets quite loud at those temps. The other is that I have an Inwin case were the cpu sits at the side of the psu. The fortron will take in the air at the back, which creates a greater heat trap around the cpu/powersupply circuits without creating a opening on top of the case.
The ideal alternative seems to be the ttgi psu : a 14 cm fan taking all the air out around the cpu and definatly much quieter at higher temps.
The prices are comparable, so seem to be the 12V rails (fortron give some to the specs , ttgi take some.
The only question left: will the ttgi hold up to the forton quality?
