It can work either way, but normally it's designed to work a
bit better blowing into the heatsink. If your case used a
design where there was a side duct which needed to suck air
out of the case with an attached, 2nd fan, that could be one
situation where it would help to flip the fan over and have
it sucking the heat away and blowing towards the exhaust

True, but on boards with the fancy wrap-around 'sinks, they
cool well enough that usually only someone overclocking and
overvolting a fair amount will need concern themselves with
which way the fan is pointed as they cool well enough either
way so long as there's still a fair amount of airflow in the
system. On those designs it often seems the weaker link is
the thermal interface between the 'sink(s) and cooled parts
under them, plus it's often the case that when someone buys
a middle to higher end board using such a design, they also
use an aftermarket heatsink with heatpipes perpendicular to
the board, fins parallel to it, and a fan on the side
blowing up or towards the back of the case depending on the
IMO, generally even though some parts produce more heat and
higher density heat, cooling has gotten easier in recent
generations because manufacturers started using larger
'sinks and they, customers, and case manufacturers allowed
for larger fans. There's still some low-end junky 'sinks
and fans tho, it's a shame when a manufacturer skimps on
these to save $1.
