okay, here you go: If the cooling system consists of a fan and a heatsink then the fan blows toward the processor, and the case fans blows th air out of the case (this is the common cooling system)
if the cooling system consists of a heat-sink and one of those long wide tubes that attach to the pocesser at one end and the case vents at the other end then the air is blown away from the processor (venting).

Always towards the heatsink. This way, there is no resistance to air flow on the intake side, so the fan blows at maximum CFM. If fan position is reversed, effective fan CFM is reduced. Less airflow results to less cooling.
BUT there are high performance heatsinks w/ dual fans in "push-pull" mode and a few where the fan is "sandwiched" by the heatsink.

Interesting debate. Do you realize a fan blowing onto anything will also blow the dust and dirt on to it, creating more heat and hotter conditions than before. The heat sinks are use to remove and dissipate the heat, why blow it back onto the processor?

Toward it,look for the air flow direction indicated in the fan.

Towards it!!!!!!!!!!!!! This way it keeps the temperature down on your processor. It’s like blowing out a candle; you don’t blow away from it to put out the hot flame.

Actually it depends on the design of the fan many aftermarket fans have funky designs. So the truth is it varies.

Heat rises so you want it blowing away
