NZXT H9 Flow

[Darksaber]

The NZXT H9 Flow is the largest of the H-Series and manages to impress with a balanced attention to detail and unique tooling, allowing for modern, bulky high-end components and elaborate liquid cooling without any tangible compromises in functionality or looks.

The Flow line keeps getting better and better. I'm digging the new PSU location.

Fun clone of the O11 dynamic, seems better than some of the other clones, I dig the NZXT holes a lot on this one. Just wish they had gone for something a little more unique though.

Wow the design objective was clearly to copy everything about the o11 making a couple changes here and there, some of those changes were quite terrible though, that HDD cage position and mounting makes no sense at all.

Is that a regular mechanical keyboard switch for the power button? If so that's pretty nice, not the first time I've seen it but more cases should do that, a really low cost way to make the case a bit more special, it's something that you'll use often after all.

....it's something that you'll use often after all.

I mean I've been firing my PC with a remote for years now , Silverstone lit me up with theirs and I got a cheap knock off alixpress and off we go That case button is a back up solution when the battery on the remote calls for replacement. I love it. Actually I'd be surprised if a company bundles one with their case.

I like NZXT's stuff. Got two PUCKs as well on my side panel. White build in this case will be a sight to see. That said I am not a target for this show piece, I still love my daily beater TT Urban R31.

I don't know about that PSU location, right behind the CPU. I would think that area would get hot even if a PSU has a fan.

Also, without any fans in the front, how is the air exchanged inside the case? It can't be using radiator fans to move air inside the case?

I'm in the market for a new case, if anyone can recommend one with excellent air flow to host a 360 AIO for the CPU and 240 AIO for a GTX 4090, then I'd appreciate it. Noise level isn't a priority, air flow and keeping the case cool is.

Of course Silverstone made that, who else

It's a cool thing, could be very usefull with HTPC's if those weren't on the disappearing side, for regular desktop the button is close enough though but I get the appeal.

The back heat is not really a problem and there's a centimeter or two of distance between the PSU and CPU backplate. The fan will ideally be turning to the back panel to get air from outside, though now that I think of it, having it turned to the inside could be interesting to pull some residitual heat from the back of the mobo maybe?

The fan configuration is the same as with an O11d, you have intake on bottom and side and exhaust out the back and top. A bit weird for air cooling but doesn't perform that bad from previous reviews of the o11. I don't know if this will get an optional front mesh panel like some other cases from NZXT and LianLi started offering, but there's other options if that's what you're looking for

I am looking at the Cooler Master HAF 700, but it's ginormous. I especially like the ability to place two rads on top, side by side. But again, its just so huge. I need something else.

Phanteks G500A outperforms it in nearly every test and costs about the same. It looks nice though. Maybe better fans, but that pushes up cost.

The set of included fans is a nice value add over the O11 and Hyte Y60. Too bad they're not PWM.

I mean, this H9 Flow case doesn't seem like a bad option for a dual-radiator setup. This style of case was pioneered by Lian Li and is designed to handle multiple radiators. Put the GPU radiator on the bottom as intake, CPU radiator on the top as exhaust, and you have the additional exhaust and intake fans on the rear and side. This is a perfectly functional airflow setup that would cool your components pretty well.

I'd probably do an O11 Dynamic Evo over this, but I do think it is a good design. It allows for a windowed case which a lot of people like, combined with decent air flow. The issue with this type of flow could be that it isn't very laminar because the intakes are perpendicular to exhausts, but it works well enough it seems. The O11 Dynamic Evo has more options such as front mount fans, inverted board, etc, for probably slightly more money ($~180 vs $160).

@Darksaber - I know the spec says other, but would a 220mm PSU fit? By the look of the pictures, it seems to be some room?
