With NZXT’s previous generation of cases, the company started off with more basic designs. For the H510 series, NZXT started off by launching their standard H510, later launching their enhanced H510i model, and later their H510 Elite. Last year, NZXT rounded off their H510 lineup with their H510 Flow, years after the release of their H510. That’s a long wait for those who wanted an H510 model with a more airflow-oriented design. While NZXT’s H710 chassis has proved to be popular over its lifespan, the PC market has changed a lot since this case was introduced. For starters, CPUs and GPUs are more power-hungry than before, making airflow a greater concern for PC builders. This change to the PC market has forced NZXT to include more fan mounts on the top of their H7 series cases, adding support for top-mounted 360mm liquid cooling radiators while redesigning their front panels to enable increased system airflow. Removing all the panels exposes just how open the H7 Flow is internally, with its forward fan mounts a full 2 inches behind the front panel. With the fans peaking at a speed of 1,200rpm, they’re not particularly powerful, so it wasn’t a surprise to see the H7 Flow return middling results with the CPU and GPU delta temperatures. However, the flip side is that it’s extremely quiet, even with the fans at full speed. The CPU delta T of 48°C was on par with the Antec NX700 and Corsair 5000D Airflow, while the Antec DF700 Flux, Fractal Design Meshify 2 and Cooler Master MasterBox 500 were a little cooler. However, the NZXT was a couple of degrees cooler than the Fractal Design Meshify 2 Compact. We'll map the results against some recently tested large ATX cases, some of which have at least a modicum of EATX support: Cooler Master's HAF 500, Corsair's iCUE 5000T RGB, Lian Li's O11 Dynamic EVO, and In Win's N515.
At the bottom of NZXT’s H7 lineup is the standard H7, a model that features a plain front panel design that will be familiar to most NZXT users. When compared to the higher-end H7 Elite model, the only major differences are the H7 Elite’s tempered glass front panel, the Elite’s inclusion of additional fans, and its inclusion of a fan/RGB controller. We’ve updated our testing hardware to use Intel’s 12 Gen “Alder Lake” platform, which has shaken up the desktop landscape (and taken prominent spots on our best CPUs for gaming list). We’re now using a Core i7-12700KF, which is being cooled by a Noctua U12s air cooler. Our graphics card is a Gigabyte RTX 3070 Ti Gaming OC. Acoustic Results for the NZXT H7 When letting each case run with their maximum out of the box fan RPMs, the H7 and H7 Elite deliver identical thermal results, proving that the Elite’s additional fan do nothing to lower overall system temperatures. This is a poor showing for the H7 Elite, and highlights the real strength of the H7 Flow. It bests the Elite with fewer fans and a lower price point. Impressively, the NZXT H7 can contain not one but two 360mm radiators. This won't be needed as even the more power-hungry Core i9 and Ryzen 9 processors will only really require a single 240mm or 360mm radiator, making this case ideal for AIO liquid coolers. With up to seven fans to install, it's possible to offset the restricted airflow.
This mid-tower case is ready to bring the cool. Featuring a perforated front and top panel, alongside widened channels, hooks, straps, and toolless entry, this sleek case will keep any build cool and comfortable while offering plenty of space. This mid-tower is perfect for a minimalist build while keeping the process simple and intuitive, utilizing widened channels, hooks, straps, and toolless entry. Since the H7 Flow doesn’t rely on a mesh front panel that doubles as a dust filter, there are filters behind the front and top panel, as well as the PSU intake. You’ll also find a tiny filter underneath the case used for bottom intake, even though there aren’t any fan mounts at the bottom.
FYI, their H700s were their 'fix' to this via a brute force method of 'just add more fans', while maintaining the stylish and air flow choking design of the previous cases. It worked, though it could've been better if they'd just done the H7 Flow right then and there. IMO, it's better than the H510 Flow, with it's limited exhaust.Curious, why do you say "too little, too late, NZXT?" After unscrewing and removing the second and third slot cover, our ATX build slipped right into the H7 Flow with zero issues. Placing the radiator on the top panel while using its fans as exhaust provides voltage-regulator cooling benefits, though at some cost in CPU temperature. NZXT can fix the H7 with some tweaks that fall far short of an overhaul but right now they still have work to do. The new NZXT H7 comes with a new side vent for the front panel to aid in providing the up to three fans with more airflow. Then there's the perforated top panel, which helps exhaust fans more easily blow out hot air. All this should provide a small improvement to cooling performance.There is a ton of information in these charts and the obvious takeaway is that the Flow front panel works best when combined with the 140mm fans running at high speeds. That will come as no surprise but when you refer to our video you will hear the huge changes in noise levels and there are times when the H7 can be very noisy indeed. In other words, the H7 can work well however you will need to strike a balance between noise and cooling. Closing Thoughts
The NZXT H710i measured in at an average of 73 C for gaming on the aforementioned CPU. Stress testing through benchmarks saw temperatures approach 90 C at bursts before settling in the mid-80s. The NZXT H7 saw a reduction in the temperature of about 5% across the board. Gaming saw an average of 71 C, which is better than the outgoing case, but still short of the N7 Flow. At 1000 RPM fan speeds, the H7 Flow continues to impress. Again, it sits towards the bottom of our graphs, delivering results that are amongst the best cases that we have tested. Again, this is a huge achievement for a chassis that ships with only two fans out of the box, and adding additional fans could result in further improvements to the H7 Flow’s cooling performance.Sadly, when looking at the H7 and H7 Elite, thermal results were less impressive, especially with regards to the Elite. Even with its additional fans, the H7 Elite does not run much cooler than NZXT’s standard H7, with both cases exhibiting GPU thermals that are 5 degrees hotter than the H7 Flow. If you want low system thermals, the H7 Flow is clearly the case you should be buying. The graph below showcases Delta temperatures with a controlled ambient temperature of 20 degrees Celsius. As its name suggests, the H7 Flow also has a large mesh on its front panel and in the roof section, so it’s geared towards offering high airflow with low fan speeds. There are a few useful features on the case’s exterior, such as tool-free side, front and roof panels that simply pop into place. There are MANY other cases like this to choose from, and they are MORE AFFORDABLE. Some of them are preinstalled with more fans; this case comes with 2 fans, when the older H710 came with 4.
