Fan setup for Phanteks P400

[19eightysix]

Had my computer setup for about a week now and my Strix 980ti is running at 80ish degree's while gaming cpu at about 40-45. The CPU is not really my concern but the GPU is running alittle hot for my liking.

 

I did not buy additional case fans at the time because I wanted to know what my temps would be prior to if needing at all, so I'm currently running the 2 stock fans that came with the case.

 

My thoughts are to run 3 120mm Static pressure fans up front then run 3 high flow fans for exhaust, I know kind of a newbie question but do I need to watch the CFM for the exhaust side to keep slight positive pressure?

I would get 2x140mm fans at front intake and run them as fast as you feel good sound wise. Then, depending on you CPU cooler, have single rear exhaust, or 1x rear and 1x top exhausts running both at half speed (or 7V).

Looking to buy this case for my next build and also want to know what fan setup would be the best. Going for two GTX 1080s in SLI so GPU cooling is important. I will be using the noctua nh-d15 CPU cooler and would prefer to use Noctua fans. Was thinking 3x 120mm NF-F12 pressure fans up front then two 140mm NF-A14 top and one NF-S12A rear. Will also be using asus ai suite 3 as fan controller.

Is this a good fan setup or are there better options for this case?

make sure there's nothing blocking air blowing under the card, did some testing on how airflow can affect gpu temps linked below, but basically it comes down to the best way to bring those gpu temps down significantly is to get lower ambient temps
