Don't Buy the NZXT H9 Flow Case Until You Watch This Review!

Summary

In this review of the NZXT H9 Flow case, the user shares both pros and cons based on personal experience. While praising the case’s design, cable management, and filters, they highlight issues like tight space for GPU cables with larger cards like the RTX 4080/4090 and challenges fitting a 360mm radiator at the top. The placement of the power supply also raises concerns about heat affecting the motherboard. The reviewer suggests considering a vertical GPU mount to avoid pressure on cables and offers advice to others with similar setups.

Takeaways

• 😃 The user has acquired the NZXT H9 Flow case and installed a 3900K processor and an RTX 4080 GPU (not vertically mounted).
• 😕 The tempered glass of the case touches the GPU cables, causing concern. The user recommends a vertical GPU mount to avoid this issue.
• 😟 The glass fits very tightly against the cables, which raises concerns about damaging the GPU or the cables.
• 🤔 A 360mm radiator couldn’t fit at the top of the case due to limited space near the CPU cables. The user had to install the radiator on the side instead.
• 😖 Custom liquid cooling setups might face problems due to limited space at the top for larger components.
• ⚠️ The power supply is mounted at the top, which may transfer heat to the motherboard, especially in zero RPM mode.
• 😬 The user is unsure why the power supply is placed at the top instead of the bottom, and they don’t see any advantage to this design.
• 👍 Cable management is a strong point of the case, with ample space for organizing cables.
• 👌 The case includes dust filters in multiple areas, such as the back, bottom, and top, which is appreciated by the user.
• 💡 If you plan to use thick or sleeved power supply cables, the tight space may cause even more issues, especially when combined with a large GPU.

Q & A

What GPU is the reviewer using in this case build?

The reviewer is using an RTX 4080 GPU in this case build.

Why does the reviewer plan on returning the NZXT H9 Flow case?

The reviewer plans on returning the NZXT H9 Flow case due to issues with the GPU cables touching the tempered glass and the inability to fit a radiator at the top of the case.

What issue does the reviewer face with the GPU installation in the NZXT H9 Flow?

The reviewer faces an issue where the GPU cables touch the tempered glass due to a very tight fit. This raises concerns about damaging the GPU or the cables.

What solution does the reviewer suggest for the GPU issue in the NZXT H9 Flow?

The reviewer suggests using a vertical mount for the GPU to avoid the cables touching the tempered glass.

Why couldn't the reviewer fit a 360mm radiator at the top of the case?

The reviewer couldn't fit a 360mm radiator at the top because it interferes with the CPU cables, creating a very tight space that doesn't allow proper installation.

Where did the reviewer end up mounting the 360mm radiator?

The reviewer mounted the 360mm radiator on the side of the case instead of the top.

What concerns does the reviewer have about the power supply placement in the NZXT H9 Flow?

The reviewer is concerned that placing the power supply at the top of the case may cause heat transfer to the motherboard, especially with power supplies that generate more heat.

What does the reviewer like about the NZXT H9 Flow case?

The reviewer appreciates the overall look of the case and the ample space for cable management, as well as the presence of filters in various areas of the case for dust protection.

What issues might arise with using regular, thicker power supply cables in this case?

The reviewer mentions that regular power supply cables, which are typically thicker, might cause even more issues with fitting them into the tight spaces in the case, especially with a radiator installed.

What recommendation does the reviewer give for anyone planning to use a large GPU like the RTX 4090 in this case?

The reviewer recommends using a vertical mount for larger GPUs like the RTX 4090 to prevent the cables from touching the tempered glass and causing potential issues.
