NZXT H9 Flow RGB+ PC Case Review

The NZXT H9 Flow RGB+ is the company’s flagship mid-tower PC case, designed to showcase a premium setup while keeping it cool and performing optimally. It’s not cheap, but for the premium price, NZXT promises enhanced support for a wide range of components, letting builders go wild with coolers and fans, in various configurations. For those with the budget, the H9 Flow RGB+ could be the endgame PC case that you’ve been looking for.

Flagship features

With its dual-chamber layout, the H9 Flow RGB+ keeps storage and the power supply separate from the motherboard, CPU, graphics card, and other main components. This has a number of benefits: it looks cleaner, is easier to cable manage, and leads to better thermals and, therefore, performance.

My most recent PC builds have utilized smaller Mini-ITX cases which can be incredibly fiddly to organize. Building in the H9 Flow RGB+ was a breath of fresh air, with this mid-tower case making the whole process super simple.

Cool it down

Supporting up to two 420mm radiators means users have the option of expanding to top-end water cooling for both the CPU and GPU. When it comes to air cooling, out of the box the H9 Flow RGB+ edition comes with two F420 RGB Core fan frames, and a rear F120 RGB Core. These are conveniently wired into NZXT’s Control Hub.

If you’re buying the H9 Flow RGB+, you most likely intend to take advantage of NZXT’s software ecosystem, aided by the included control hub. To save future headaches, I’d be prepared to keep it locked to NZXT components and accessories.

Glass meets airflow

Once the build is complete, the wraparound glass panel makes for a super-modern touch that really elevates a system’s look. Whether you’re opting for extreme RGB lighting or minimalism, or something in between, the glass panel should help give aesthetics a boost.

I’ve been very impressed with the H9 Flow RGB+’s thermals as, during testing in intensive games and stress tests, it’s clear that airflow was a top priority for NZXT when designing this “Flow” case.

Some downsides

When it comes to downsides, there are a couple of things I’ve got to mention. First is the price. At $289.99, this RGB+ variant is far from cheap. Potential buyers will want to be certain that the NZXT ecosystem is one they want to become immersed in. If that’s the plan, then the RGB+ is a solid foundation to build into.

The other downside is the stock noise profile of the fans. Users are more than likely going to want to dive into NZXT CAM or the BIOS to fine-tune those settings, which adds an extra step to the process.
