Hey guys I need help deciding which Noctua fan to buy.
I can get a AF15 twin pack for $37 or two separate AF14 ULN for $36 on Amazon.
But here's the thing, I only want to buy one pack or the other because buying two different fans separately is way more expensive.
I can get the AF15s for the bottom intake and the rear exhaust while my 2 stock Fractal fans are in the front
I can use one of the AF14s on the bottom intake and another on one of the front fans (in front of the HDD) while one of my stock fans fills the other placement on the front and the other for the rear exhaust.
Which configuration will yield the best cooling performance in general? Also, does the AF14 ULN fan push a lot of air even though it's ULN?
Noise isn't THAT much of a concern but I have it in mind.
Can you get PWM ones instead and use mobo headers to control the speed?
I suggest SP140 PWM (or get a better fan for less money) and use PWM control with PWM splitter using CPU fan header PWM signal and PSU power. Front will have much better airflow with cooler fans instead of case fans.
