I am in the process of building my cooling system and realized that my space is limited. I was wondering if you all think I should have a dual push/pull system on both my radiators.. or even if it is necessary. Also, any suggestions for great push and pull fans would be great as well.
You don't need push/pull, but you might get an improvement in your delta from it. It all depends on fans used, ambient temps and if your rads are internal or external mount and any airflow limitations (if internal- see: ambient temps).
I was able to fit a push / pull set on one the 2x 120MM rads in the front side of my case. The problem lies on the top side of my case where I cannot clear my motherboard in the my mid sized case. I would have to test my ambient temps I guess.
