So I've done a bunch of builds in my day, but I am going for the ultimate machine on this one so I wanted to get some feedback on my configuration so far as its a little complicated. This is a DIY water cooler build btw.
I've got a NZXT Switch 810 case, The 8 core FX CPU with a water block, 2x HIS 6950s (modded to 6970), each with Heatkiller full coverage water blocks and a Heatkiller crossfire bridge. This will be in my system with a 420mm rad and a 240mm rad which might be overkill at the moment but Heatkiller makes a full cover chipset block that I plan on adding.
Anyway I am at a crossroads right now with fan selection and direction. First question I wanted to throw out there is about airflow direction. I've always been under the impression that cool air should be pulled in from the front and then exhausted out the top and back. Recently I've been reading a lot of people saying you should pull air into the case through a top mount radiator, but that just doesn't make sense to me...
I am also a fan of push/pull when it comes to rads so as of now this is my projected fan layout. 2 front intake NZXT FZ140 140mm fans (83 cfm), another of these in middle of the case pointing at the video cards. I have an arctic cooling pwm pst 120mm exhaust fan on the rear and here is where it gets tricky since I have like 50 fans total from old builds and stuff. I want to use my 6 Xigmatek 90 cfm <18 dba fans for push pull on the 420 with the air being blown through the radiator out of the case and then use 2 cooler master 120mm 90cfm with 2x xspc static pressure fans for push/pull on the bottom blowing up.
What I am on the fence about is regarding static pressure because I have 2 corsair SP120 fans and I also have some 100+ cfm fans. I am going around in circles so any input would be greatly appreciated
