Which fans?

[Gabbatek]

I've got two 980ti hybrids with both their coolers venting out of the top with the fans on the inside of the radiator pushing out.

Im thinking of adding two more 120 fans to the hybrids radiators that will run off one of the mobo fan headers.

Should i use static pressure fans? At the top of my case, which side of the radiator should i have the gpu controlled fans for extracting that will cool the best? Bare in mind two other fans controlled by mobo will be helping.

hope that makes sense lol

Do you want to have 2 fans on each radiator? If so you have to have the fans on either side running the same speed as each other otherwise it can cause problems.

Basically you want fans with high pressure rather than fans that can push a large volume of air. Noctua are the best for performance and noise but sadly look a bit naff.
