Please see both scetched setups:
This setup has my H100i V2 in the front with 2x 120MM intake, at the top 3x 120MM outtake and at the end 1x 140MM outtake.
This makes a total of 2x intake and 4x outtake, this will make a negativ airflow
This setup has my H100i V2 at the top with 2x 120MM outtake, 3x 120MM at the front intake and at the end 1x140MM outtake.
This makes a total of 3x intake and 3x outtake, this will make a neutral airflow
Which airflow do you guys recommend?
I will connect the 3x 120MM with a 4-Pin PWM Splitter (1x PWM -> 3x PWM) 30CM Sleeved Black.
I will connect the 2x 120MM with a DarkSide 4-pin PWM Dual Fan Power Y-cable Splitter - Jet Black
I will connect the 1x 140MM with a 4-Pin PWM Fan Extension Cable 30CM .
Also which program can I use the best to control my fans?
I hope you guys can help me out.
Do you own a 'reference' design blower-style cooler or a 'non-reference' design? Generally blower-style GPU's are not impacted by radiator positioning, but I've seen a few tests performed where a non-reference design air cooler from an AIB partner like ASUS or Gigabyte are affected by radiator positioning. From what I've seen installing the radiator at the front of the chassis was better for CPU temperatures. The reason for this is due to the hot air that the non-reference designs emit that isn't exhausted properly. All the hot air is drawn through the radiator at the top of the case and inefficiently cools the radiator fins. Compare that to a front-mounted radiator that draws its air from outside the case. Rarely will a front-mounted rad affect GPU temperatures by anything more than 1-2°C. A GPU does not need super cool air to perform well.
However, this may not 'the best' way to install your radiator as the EVOLV has restricted intake. Therefore the radiator may be better installed in the ceiling. If you're able to, test both setups and compare temperatures. That's the best thing to do. Don't worry about positive/negative pressure. It's an overrated concept and holds little impact on temperatures or dust buildup. Guys like Singularity Computers have pushed these ideologies to death and it's really not as important as people say as you should still clean your system every few months. If you're able to create positive pressure, do it, but don't fret over it.
Also, I second the installation of an intake at the back. Whether you install the radiator at the front of the case or the top, an intake at the rear is likely going to help CPU or motherboard temperatures. Again, this isn't definitive. Test both configurations and see for yourself. There is no wrong or right way to do it.
