Well...
The ambient air is being pulled up through all of the fins on the heat
sink.  This is roughly the same as the ambient air being pushed through the
heat sink.  I'm not sure it would make any difference if it was facing the
other way.  In fact, if you push the air towards the cpu by having the fan
blow on to it, you are actually forcing the air to stay close to the cpu
for longer.
Your overheating problem would probably be better addressed by going to an
aftermarket heatsink & fan combo.  Also, perhaps another fan bringing cool
air in to the case and one more to exhaust the hot air.
