Should I have a fan on a heatsink blowing onward onto the heatsink or away from the heatsink ?

You really could have asked this in your other active (and recently posted cooling thread). Locking this one.

But the answer is facing down, or more specifically for your heatsink, blowing the air downward into your heatsink.

Ok thanks. Sorry.

You can merge them if you would like!

Just to make sure I understand you right so the fan blowing onto the heatsink right ?

You are talking about push or pull setup on the heat sink fan.

As UsandThem stated, its marginally better to have them push then pull, meaning push air though vs pull.

However for maintenance and cleaning sake, it is much much easier to have the fan pull, meaning pull air though the sink, as you can get a vac on that other side and suck up the dust bunnies without having the fan get in your way.

He posted it in a duplicate locked thread, but he doesn't have a tower style cooler, so he is limited to it blowing downward on to the heatsink, VRM, and caps, IMO.
