Help me achieve the best airflow on Corsair's 400C case !

ChanceTheRapper

Those stock fans that you are "obviously" not going to use are not bad fans. At all.

 

If you don't like how they look that's one thing, but SP120's don't suck. They blow;)

If you're just gonna stick to the two it's coming with, keep them the way they are.

 

If you want to add more, add them to the front as intakes before you add any to the top as exhaust. You want to have equal or positive air pressure, so you should never have more exhaust fans than you do intake, though having the same of each is okay.

 

and if you're looking to replace all of the fans, I'd suggest Corsair's new SP120 RGB fans. If you think those are too pricey, stick with Corsair's AF120's. Either choice will give ample airflow. Remember that if your fan is up against a radiator or a heatsink, you should be using Static Pressure optimized fans over Airflow fans. the new SP120's I'd say are an exception, as I use mine as airflow fans and they perform really well.

Feel free. Looks like you've made your decision, not sure why you asked in the first place.

 

Noctua fans are really expensive and are ugly in my opinion, even the new style. But hey, you do you.

You only need three fans really. Two intakes at the front and one exhaust in the back. Everything else after that makes little to no difference. 

 

Just get three of your favorite Noctua fans with PWM headers (the fans that list multiple RPM's, dont get that 3000 one) so you can control the speed, and then you're all good.

Anything but iPPCs. If you are already going for Noctua, I assume its because you want silent system. In that situation, you will be running them at lower rpms anyway, maybe not at max rpm at all. Like I have 2x A15s which are limited to ~1300rpm max.

Why not stick with the stock fans?
