Hi All, my query is with the fans that you attach to your radiators. when attached you see with some fans there are gaps between each fan. do these gaps create a lag in the pressure they can push. also is there any point on trying to fill in these gaps to increase performace slightly.

Please clear this up for me :)

No, you'd actually want the space to help with airflow. In fact, many people add fan spacers or ducts to offset the fan further to help eliminate the deadspot from this and allow a more uniform air entry without a dead zone behind the fan hub.
there is a gap or void between the fittings where a fan is attached and the start of the copper pipes and fins as seen in this. there are also small gaps between each fan fitted. could we fill in these gaps with something to enhance directional pressure.

see slight gaps between fans.

You mean the mounting tabs on the radiator and the cooling tubes and fins on the radiator? There is supposed to be a gap here...it helps lessen the dead zone where the fan hub is located over the radiator.

Unless I'm missing something? Are you suggesting making sure the fan is flush against the cooling tubes and fins?
