FWIW: proper ATX power supplies pull fresh air thru the power supply and
blow it directly across the CPU assembly... exit ports in the case vary
from there... true ATX power supply fans are not accessible from the back
of the case, either...

unfortunately, many ATX power supplies are simply reworked AT power
supplies and do continue to do things the old way...
