Does anyone have a recommendation for reliable case fans?

So my parts will be coming in this week but I haven't been able to decide on a set of case fans for my Define S. I did some research and it seems that Noctua NF F12s are really good but the price seems a bit high for the performance. I'm also really conflicted with if I should go with air flow fans or static pressure fans, seeing that the Define S has no HD cages blocking intake. Currently, i'm not doing any liquid cooling and I'm just trying to keep my temps as low as possible without sacrificing too much sound. Let me know what you guys think!
