    Hey!

    i have an old Fractal Design R5 Case whit the stock Fractal Design Dynamic GP-14 140mm fan's
    2 in fron and 3 Top Back and side as Exhaust.

    And i am up for an upgrade of those fans, As i recently upgraded my CPU fans Into Noctua NF-F12 In Pushpull

    so i got my hands on those and this is my idea of the setup!

    3 Noctua NF-A14 iPPC-3000 140mm PWM ( 2 Front intake and 1 back Exhaust)

    2 Noctua NF-A14 PWM chromax .black.swap ( 1 Exhaust side and 1 Exhaust top-back

    Will it be a disaster or failure airflow ?

    No need to have a fan on the side pushing air out. It should be doing the opposite.

    Heat rises. Because it's heavy.

    Bottom fan should also be an intake. I have 3 bottom instakes, 3 side intakes, 3 top exhaust(radiator), 1 rear exhaust so 10 fans :D

    That's gonna be LOUD, the A14/A15 fans have a terrible sound profile above 900 RPM. Those fans need to be replaced asap and burried.

    And that comes from someone who loves Noctua.

    Is it enough to keep the components cool?

    Absolutely. Bought my case specifically because of its airflow characteristics. If I wanted to stick with air cooling, I could get by on just 2 intake fans, but I hate hearing fans spin up....lol
    I usually spend most of my time on system builds, just determining optimal fan positioning for minimum fan count.

    I was running an R5 2600 and RX5700 when I switched to this case. It has a pair of RGB fans for intake.... The stock fans are actually pretty decent being rebranded Phanteks fans. They're still in their default locations, since that was the optimal location. I just added an Artic Liquid Freezer II 240 RGB....cuz my air cooler wasn't sufficient for my 5600X And yes, the RGB was intentional....lol

    Sometimes, you just gotta have the RGB....

    good 2x140mm intake and 1x140mm rear exhaust is all you need
    quality not quantity

    get a case with normal intake, preferably mesh or fabric.
    i've a fabric front on my p600s and it's super non-restrictive, and easy to clean under tap water.

    Yeah....I'd have to ditch at least 4 of those fans....lol

    This is my case.

    I too love Noctua, but I also have to agree these fans above 900rpm are pretty whiny and at full speed you would be at a detriment. More airflow sure does mean cooler components, but there is a limit/sweet spot. Going above the limit/sweet spot won't lower the temps anymore just adding more noise for no reason.

    true
    try alpenfohn fans,they're great for high rpm
    not particularly cheap but excellent quality. I have a 3x120 wingboost3 pack for case intake and believe me I prefer them at 1600rpm than a15 at over 1000.
