NZXT H5 Flow Review: Refreshing The Classic

NZXT H5 Flow

NZXT has released the H5 Flow PC case, a successor to the massively popular H510 Flow PC case. Aside from the Flow, NZXT also released the H5 Elite, which features a glass front panel instead.

It is available in black and white, and we have received the black version for review. Read on to learn more about our thoughts on this PC case.

Like any other NZXT PC cases, the H5 Flow has a minimalist and clean design. Compared to its predecessor, the H5 is slightly wider, allowing more room for cable management. The front is covered by a large mesh intake panel with a dust filter backing, which allows for tons of airflow. The top now has a wider mesh panel allowing for a radiator up to 240mm in size.

One key feature of the H5 Flow is the additional bottom front fan, which is mounted to a plastic housing and angled towards the GPU. Considering GPUs can get quite power hungry and toasty these days (looking at you RTX4000 series), this is a nice feature to have.

H5 Flow IO
Front I/O

In terms of drive bays, it is not a lot. You only get two 2.5″ and a single 3.5″ drive bays. While it is sufficient for most PC builds, running drives on RAID is out of the question. The same applies to front I/O as well. You get a USB Type A and a Type C port, plus an audio jack and nothing more.

How Does It Feel To Build?

One notable difference when compared to the older H510 is that the H5 Flow is easier to cable manage. Instead of narrow plastic channels to guide your cable management at the back, the H5 Flow has a simpler solution: velcro straps. This allows for more flexibility as I do not have to bend cables in a weird angle and stuff them all into the channels.

H5 Rear Panel Space

The space between the motherboard and top mesh is also slightly taller, making it easier for me to install radiators, and routing cables around.

Overall, newbie and veteran PC builders will have an easy time to build inside the H5 Flow. It does rattle and creak slightly out of the box, but once everything is installed, it feels pretty solid.


Thanks to the airflow focused design, thermals are on par with other leading airflow cases. Two 120mm fans are already included (one at the back, one for the GPU fan), so builders can save some money here. During heavy gaming and editing loads, we managed to get temperatures hovering between 60-70°C.


NZXT H5 Flow Review: Refreshing The Classic 7

For the price of RM369, the NZXT H5 Flow is a well-built, straightforward PC case. It is a noteworthy upgrade from the H510 series thanks to a myriad of airflow upgrades such as the GPU fan and expanded top mesh panel.

Couple that with a simplistic and clean design, you just got a sleek PC case that fits nicely in any modern home.
