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 graph below showcases Delta temperatures with a controlled ambient temperature of 20 degrees Celsius. The snap-off top panel also includes a filter, but this one connects to the chassis underneath. The filter covers a mount that can hold three 120mm or two 140mm fans, as well as any radiators of corresponding proportions.
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. What stopped them from launching meshed versions alongside the older cases? For a comparison, Fractal has their Define and Meshify(recent Pop Air too) series.
The Verdict: A Mainstream Winner of an ATX Tower
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. 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. The extra SSD trays snap onto the round holes of the power-supply shroud…or pretty much any other vent holes you can think of. But we’d rather place them here. If you were looking at the front of the H7 and though “but where’s the airflow going to come from?”, the H7 Flow is the case for you. The H7 Flow is the same case as the standard H7, including the same fans out of the box, internal layout, and price point. There are only two differences between the H7 and H7 Flow, and those differences are the case’s front and right panels.
Thermal performance is an essential factor for any PC case. Your system may look fantastic and seem silent from the outside, but all of that is for nought if your PC has the internal temperature of an oven. Your PC case needs enough airflow for your components to remain cool under load and to prevent any form of thermal throttling. For our test, we used the following hardware using fixed fan speeds (so that only the case and its included fans can influence thermal performance). The NZXT H7 is in quite the predicament. The H7 Flow is by far the better PC case. It has better thermals, is the same price, has all the same features and has a completely clean side panel thanks to the large intake vent upfront. If you want something a little fancier, the NZXT H7 Elite has more tempered glass than you'll know what to do with. 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. If you’re looking to add a bunch of hard disks, sadly there’s just the basic two 3.5in mounts in a removable cage in the base of the case, which can also be used for 2.5in SSDs, in addition to four dedicated mounts for the latter behind the motherboard tray and on top of the PSU cover.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.
The H7 Flow hangs in with the HAF 500 for middling noise levels, beat only by the O11D EVO’s reduced fan set. But that’s with all cases being measured from the front-left and front-right corners. What’s not shown in these numbers is that the H7 Flow became noticeably louder from above the top panel after removing its top filter, which is an angle that we didn’t have other data to compare. 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. 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. Our starting point for this review of the H7 family starts in 2019 with the H510 and H710, which were interesting cases that leant heavily on looks and styling, and rather less on performance.
NZXT H7 Flow
Practically speaking, the thumbscrew that secures the drive cage is what limits power-supply length to 233mm. A second set of tab holes and screw holes allows it to be moved about 19mm farther forward, but placing it there reduces the lower portion of the front radiator mount by the same distance. The 3.5-inch cage’s optional 2.5-inch mounts aren’t even included in the H7 Flow’s official specs, as those specs instead refer to a second set of 2.5-inch trays that we’ll cover momentarily. 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. In all, the H7 is slightly smaller than the H710, and it is significantly lighter. The H710 was 12.1 kg, and the new H7 is 10.26kg. That said, both cases support the same levels of CPU clearance, front fan/radiator clearance, and cable management space. The only compromise with the new H7 is that is has 13mm less GPU clearance, not that 400mm of clearance isn’t enough for practically all modern GPUs. Corsair Dominator Titanium First Edition DDR5-6600 C32 2x32GB Review: Abundant Capacity And Performance Our acoustic test consists of three scenarios: We run the CPU at full load, the CPU and GPU at full load, and an optimized mode. The CPU full load test runs the CPU and case fans at their maximum speed. For the CPU and GPU full load acoustic test, we also stress the Gigabyte RTX 3070 Ti Gaming OC and set the fans at 75% speed, because in gaming the fans never run at 100 percent and are far too loud when they do.
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. Even with an AMD Ryzen 9 5950X processor, you'll see a good 5% reduction for average temperature in games. It's still not quite as good as some other PC cases, namely the be quiet! Silent Base 802 or NZXT H7 Flow, but it's good to see lower temperatures all in keeping the same overall look of the existing H710. 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.
The Interior Features: Easy Peasy Building
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. IMO, it's better than the H510 Flow, with it's limited exhaust.Curious, why do you say "too little, too late, NZXT?"
Great Deal
