I push on the cold side and pull on the hot side

Should be quieter if u have them on the inside of the case pulling in fresh air through the rad from the outside. The rad should muffle some of the fan noise.

Hmmm 4x fans, 2x fans pushing cold from inside the case through the rad to 2x fans pulling air out of the rad through the top of the case?

sounds good, would i need 4 shroud's

High cfm/speed/static pressure - Push
Low cfm/speed - Pull

By no means a solid rule but lots of rad reviews seem to show a rough trend in this direction.

If I'm wrong with this can someone please correct me - I'll need to reshuffle my fans.

You dont wanna be cooling your rad with hot air do you? The main parts of your rig that you wanna keep cool are under water. Your temps will be lower pulling cool air in.

This man is on the money. Use shrouds too if you can

Turning point is around 1400-1600rpm I believe
