NZXT H9 Flow Dual-Chamber Case Review
Complete System

NZXT has built a great case here, and admittedly, it’s very pretty. However, it is also nothing we haven’t really seen before. Big, dual-chamber, dual-tempered glass and even pillarless glass cases are nothing new. However, the ultra-clean and modern aesthetic is uniquely NZXT and a superb addition to their already impressive range of cases.

One of the big selling points of this case is that it can support nine 140mm fans (and a single 120mm fan in the back), which means it can easily handle the biggest, newest and most high-end 420mm AIO cooler that NZXT has just released!

Oh, and what a surprise, I have one and it’s in this case right now, brilliant! It does look superb, though, and the fact that I can mount it in multiple locations in this case really gives you a lot of freedom. You could go for a full custom loop here, have a 420mm AIO for your CPU, and even have a liquid-cooler AIO GPU too.

There’s no air cooler that I can think of that wouldn’t fit here, so yeah, no issues. While the case is obviously well suited to liquid cooling, I like air cooling a lot. Having 9 140mm fans running at low RPM plus a quiet air cooler, this case will be as quiet as a cloud.

Overall, NZXT has a fantastic case here; it’s big, it’s well-made, and with those massive side panel windows, you can really show off your building skills. That being said, if you don’t have great PC building skills, there’s so much space behind the motherboard, you can cram all your sins out of sight and get great-looking results anyway.
