Unless you have more than 1000 watts of heat producing components in your system, three fans of 120mm or larger will be plenty, you shouldn't need more.
If a specific component in your system is overheating, suspect its heatsink and cooler before you point your finger to chassis airflow
nah u wont but u wont need that many 3 is fine i am running 3 on a custom set up no issues runs stone cold @ load on an intel set up
I'm sorry for calling you out on the forum, but I believe it's unspoken policy to use proper English when posting on Tom's Hardware. Thank you for your contribution.
yeah ur wasting $ on fans u dont need i run what i can just make sure ur heatsinks are screwed down properly & fan direction is the correct way facing on a gaming set up i am running 2 fans 1 cpu stock fan no issues under bios fan setting in a gigabyte motherboard make sure the push pull set up for airflow to the case is right u wont have issues i barely reaching 40 deg on peak load its how u set them up in the first place i use old 2nd hand pre built cases not getting fancy no issues on the cheap dont look the best but preform & set up a few the same way no overheating @ all hottest seen temps reach bowt 47 deg
