Or should I figure out a way to reverse the fan flow direction in the new power

To reverse the airstream, you have to turn the fans, by opening the psu,
and turning it around. The standard now is front intake with or without
fans, and only psu exhaust fan, or another additional exhaust fan.

I'm having 2 papst 80mm fans in front, running on 6 v, and the psu
sucking out. That is however to little...
