First of all thank you ALL for your effort , especially Monkeypoo and Salavanos
I will mention all problems and number them.
1.)The negation of airflow by putting intake/outtake next to each other.
I have actually never read anywhere that two fans could negate each others airflow if put next to each other when having different push/pull designations.
You have to imagine the airflow like a barrel ...if you put two fans next to each other the barrel of air cannot be impeded by either one ....but
once the barrel expands as air is gas not the negation of airflow but rather of the sense of cooling is enitiated.
Example:exhaust blows the air out and the intake fan right next to it sucks the hot air back in the case.
Monkeypoo already mentioned that and he is completely right!
Only one thing though....the hot air mixes with the cooler ambient air first so it wouldnÂ´t be 100% bad case exhaust air but rather 50-40% cooler air because it had the chance to mix with the ambient air before being sucked in by the intake.
So letÂ´s give the top 2x120mmexhaust + top 2x120mm intake idea a B- .
2.)Salvanos brought up a pretty nice idea ....in his first picture.
4x120mm intake + rear intake + front exhaust.
Basically that would be a very nice idea for a normal gpu setup.
This positive pressure would be great for reference cooled gpuÂ´s.
But please consider these are Twin Frozr III CF.
Those coolers will exhaust most of the hot air into the case.
So the heat would only mix and cluster with a 90% intake / 10 % exhaust fan setup.
Which is why I give this idea a C+
3.)Then there is the 90% outtake + 10% intake theory which is displayed in Salvanos second picture.
I think this is one of the best ideas because the TWFIIIÂ´s exhaust air will be exfiltrated to a 100%.
The only weak point is the intake capability.
A single 140mm intake from the front which is about 3 foot (80cm) away from the gpuÂ´s is just not enough to supply them with sufficient cool air.
The success of this theory depends on how the TWFIII work and what they prefer a good exhaust and can cool on neutral air ..or if they need good exhaust + good intake.
Which leads us to my personal idea
4.)left top 2x120mm exhaust + right top 2x120mm intake + front 140mm intake
In theory this would be the best of all ideas but unfortunetly there are too many flaws and unanswered questions in it.
Will the intake fans suck in the hot/mixed hot air back into the case even though they are very low RPM?
Will the fans even negate each other or will they be able to work independantly?
hmmmm not sure yet
Also please note the 140mm fan option in the bottom of the upper section and top of the lower compartment is where the PSU will be installed ...no fans there^^
