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. 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.

The NZXT H7 Flow is capable of handling not one, but two 360mm radiators — one on the front and another up top. The rear panel has a 140mm fan and radiator mount, atop of seven horizontal PCI slots. There aren't any vertical slots with the NZXT H7 series. Finally, we've got the single tempered-glass window panel, which showcases everything instead within the case. Voltage regulator temperatures show why this builder prefers to put the radiator (and its extra fans) on top, as the N515 fell well behind the H7 Flow’s clear win... While temperatures were higher than they could have been with better access to air, NZXT was comfortable at the time to mix form with function. For the new NZXT H7 range, the company has redesigned how the cases both take and exhaust air. The NZXT H7 Flow is the biggest change here with the perforated front panel. 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.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.ÂÂ

NZXT’s user-friendly approach shows during setup. The H7 Flow gave me an extra advantage of installing six fans, ahead of installing my motherboard. It’s roomy enough for builders to experiment with different fan placements. I had no trouble fitting my ATX size Z690 Elite AX DDR4 motherboard on pre-screwed standoffs. Let alone a liquid AIO cooler on the roof of my H7 Flow. Those pop-out panels reveal tight columns to screw radiators on. The NZXT H7’s design is very skeletal– especially the front panel, which is nearly all perforated. Because of that, I wasn’t expecting a quiet case, but I was wrong– very wrong. Now, this case isn’t quite church mouse-level silent, but for an airflow-focused case, I’m quite impressed. The only case that goes toe-to-toe with the H7 Flow on our chart is the Hyte Y60, but two of its three included fans are in the basement, and it has a whole lot more glass going on to keep the noise down. Thermal Results for the NZXT H7 FlowThe 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. 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. 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. 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 dust filter at the bottom of the intake duct wouldn’t make much sense if the face panel didn’t also have a filter, so NZXT equips the H7 Flow’s snap-off front with a snap-in plastic-framed filter that covers the entire ventilated section.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. I've gone into some detail about the NZXT H7 series refresh in my NZXT H7 Flow review, but the goal NZXT's designers had in mind was to keep the same look but refine the cooling performance. This was carried out by adding a new side vent for the front fans to gain access to more cool air, as well as a redesigned top panel. The NZXT H7 Elite is good for those who want to create a statement visually with the front window, whereas the normal H7 would have been good for those who don't wish to pay as much if the H7 Flow didn't cost the same. This makes it the best NZXT H7 option for those who don't want more than one tempered-glass panel (and the included RGB/fan controller hub). As expected, NZXT’s H7 Flow delivers much lower CPU and GPU thermals than the standard H7, so much so that the case is one of the best performing cases that we have tested with 600 RPM fan speeds. While the case does not offer cooling that is on par with Fractal’s Torrent chassis, it gets remarkably close for a case that only ships with two fans out of the box. If we added a few more fans to this chassis, maybe we could expect CPU/GPU thermals to lower even further.Â

With the front panel being perforated, the H7 Flow’s right side panel can be completely closed off. Unlike the H7 and H7 Elite, the H7 Flow does not require a perforated right side panel for airflow, allowing NZXT to ship this model with a plain right side panel. The excellent cable management, better thermals, and updated design make the NZXT H7 series one to watch out for. Obviously, the H7 Flow has a perforated front panel, allowing the case’s front fan (or fans) to intake air directly from the front. This maximises the H7 Flow’s air intake, making it the best performing H7 chassis in terms of cooling performance. Aesthetically, some users may prefer the H7 or H7 Elite, but for those who want the best cooling, the Flow will be the way to go.ÂThe H7 Flow’s bottom panel features slide-out filters for both the power supply and the intake gap. While the front filter and its corresponding hole seem unnecessary on a case that has a fully vented face, the same underlying chassis also fits the unvented face panels of its two sibling models. And behind the motherboard is where NZXT's years of experience truly shine. The cable management with this case (and other NZXT H7 series cases) is in a league of its own. It's exceptionally good and makes it possible for even novices building their first computers to put together a tidy rig.
