Hi TS,
no one can actually suggest what's right for you. you will need to test it out yourself which is what
ragnarok95 mentioned. It takes time and the most important part is patience while doing this.
Below is just for your read, if you find it lengthy ignore them.
PC Airflow is no difference from torquing a vehicle, you might get good parts but if you do not know how to torque it, it's as equal to driving a default settings.
Some factors you might want to consider.
1) Determine what kind of user are you? for leisure, work or gamer.
2) PC cooling and cooling fan used?
as listed on your diagram, you are using non AIO cooler for your processor but what fans are you using? normal or particular? Example noise factor, CFM (air/wind strength) and yes many can just use Noctua. No doubt they are of good build and produces less noise but there are cheaper alternative.
3) What kind of style are you looking for
a) Positive airflow - all intake, which lead to less dust accumulation (just make sure your case does have fan filters)
b) Negative airflow - all outtake, which lead to hell lot of dust accumulation inside your case.
c) Balance airflow - the hardest to achieve but is not impossible
don't be mislead by others, have your own concept and work on it. Yes you might see bros here talking about Noctua most of the time, no doubt they are quiet and give good airflow but there are other alternatives.
4) Making use of UEFI or the software that comes with your motherboard to tune rpm vs temperature.
which most does.
5) There are three zones to consider, 1st section (CPU Zone) , 2nd section (GPU Zone) , last section (PSU Zone) , which you will need to understand and to be able to control the airflow inside your case.
Again you have to try out by yourself.
These are my personal experiences.
I do take in suggestion and quietly take my time to plan and to torque the airflow. I mainly use my pc for work, video edit, 3D and graphic works. I am not a hardcore overclocker as I do not fix a voltage and run it always at high Ghz (some will do it straight 5Ghz) this will damage pc component in the long run and will warp the PCB of your motherboard or GPU or Rams. It does not matter how much you bring down the temperature as pc component are constantly generating that much heat.
I have my reasons to do the below illustration as I need my PC to be functional till the end of time (at least 5 years down the road)
Am using a LanLi Lancool II case (without mesh infront)
I did this to give more air flow at least to the PSU and GPU area
Purposely mount my radiator this way for easy maintenance (dust is a factor on airflow)
Purposely mod this GPU like a box so that only hot air are pushed to the back an not inside the case
I know the strength of my fans and to use this application
"SpeedFan" to have total control. you can find the guide here by Jayztwocents
I am happy of what I have archive in temps, performance and cleanliness of the case.
As said, some might say why waste of time. well to me is worth spending time on something I love. I gain to learn more and being practical in whatever I practice with, be it in life or at work.
