I got a Coolermaster Centurion 5. I don`t have all the other parts yet so I started wondering what kind of power supply to get. I was thinking either Fortron or Seasonic then I read this odd comment on a customer review for a Fortron that the fan blew the air downward. I looked at the direction of the fins of the fan on that model and a Seasonic as well and it looks like they both blow the air down. Well, woudn`t that mean that the air coming out of the 120mm fan in the back of the case would just end up being sucked back in by the power supply? Both these power supplies only have one fan.

So, in other words, it seems that getting an Enermax would be one of the only ways to guarantee that the hot air from the processor ends up going up and through the power supply. Is this really the case? Am I being too paranoid?

BTW, if anyone of you tried to figure out how to get a 40mm fan on a Zalman NB47J, I found a way. I used two 6-32x2 bolts and screwed them in on one side. I hope I got the size correctly because I don`t understand the `standard` system. I understand the metric system much better.

Also, since I read that single rail PSUs are better for SLI or Crossfire, I figured it would be better to get perhaps a 550 watt Enermax EG651P-VE with a 36A single rail. Doesn`t that just rock? What kind of problems could you have if you only have a single rail?
