Installing a fan on videocard: should the air flow inwards or outwards the heatsink?

Which works best? pushing air inside heatsink or expelling hot air outwards? |

Install the fan so it blows down on the heatsink.

Yes, I tried it sucking off the heatsink. Doesn't cool as much. You get about 25% better coolling if it blows on it.

Can't pull/intake air from inside the heatsink as it can from the open case.
