Best fans for the NZXT H440?

I’ve been noticing that almost everyone who picks up an NZXT H440 tends to swap out the stock fans right away—usually for some Noctua ones. I guess I'm wondering if that's actually necessary, or if it’s even worth the upgrade? I was thinking about maybe putting three 120mm Noctuas in the front and maybe a 140mm Corsair fan on the back... though I'm not really looking to drop a ton of cash on this. Just wanted to poke around and see what you guys think.

NZXT puts pretty solid fans in their cases. And by the way, their stuff isn't some cheap junk either; it’s actually high-quality gear. In my humble opinion, swapping out perfectly good stock fans is just pure insanity...

Also, don't go overboard with the fan count. You'll just create turbulence inside the case and end up with the exact opposite of what you're aiming for. You'll basically just be swirling hot air around inside the box.

The Boeing comes with 3x120mm fans in the front and 1x140mm in the back, which is more than enough for great airflow. If you decide to overclock and realize things are getting too hot, you can always add 2x120mm fans to the top to exhaust the heat from the CPU. I wouldn't touch the side mount—don't mess with the airflow pattern.

If the impossible happens and you somehow hate the original fans (though I honestly don't see why you would), you can always swap them easily enough. But throwing that much money away just because of some weird obsession or nonsense you read online? Seriously... you're better off buying a decent meal and a drink if you've got nothing smarter to do with your cash...
