Common to blow air in???? About the only type of situtation that might be
normal would be with a BTX standard PS, not an ATX designed PS

you provide better cooling by drawing the heat away from the cpu and up and
out of the case. not blowing hot air from above back down onto the cpu from a
hot powersupply. Contact the rocketfish people at
http://www.rocketfishproducts.com/ and ask them if how your PS is behaving is
normal to their design.

There is probably a reason that there are so many "open box" rocketfish PS's.

Agreed, but i would have preferred a power supply that has two fans, one large
one like that , plus one in the rear.

Maybe I'm missing something obvious here, but ever looked at a fan from
the back? Most have screw mount points on both sides...

Yes, of course but even if you turn the fan around and mount it the opposite
way the motor still turns the same way.
