Better to push air through radiator or pull through?

[gulfcoastfella]

Because of my case layout, I have to pull air through the radiator rather than push air through. How will this impact the radiator's performance? Will the fans be less efficient the way a pump pulling pressure is less efficient than a pump pushing pressure?

If I absolutely have to push air through the radiator (which will mount inside the top of my computer), then air will flow in the top of the computer and out the side, back, front, and bottom. I understand it's better for air to flow up and out rather than down and out since heat rises.

Usually it's quieter for fans to pull, but it's not as effective.

I thought it might not be. Does anyone else have similar or alternative answers?

Pulling through would be better.
