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. However, it’s a shame the case doesn’t have full E-ATX support, with the width limit set at 272mm. The main holes at the front of the case have a large cover to hide them as well. Overall, it’s an easy case to keep tidy, with plenty of stowage for excess cables, lots of anchor points and cable ties. Build quality is also excellent throughout, with minimal panel gaps and all the parts fitting snugly together. 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. 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. 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.

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 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 Flow 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.

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 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. Cooling:3 x 120mm/3 x 140mm front fan mounts ( 1 x 120mm fan included), 1 x 120mm/140mm rear fan mount (120mm fan included), 3 x 120/2 x 140mm roof fan mounts (fans not included) 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.

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. With the top filter installed, the H7 Flow’s CPU temperatures are a close match to those of Corsair’s iCUE 5000T, beating both the Cooler Master HAF 500 and Lian Li O11D EVO. In Win’s N515 leads in CPU temperatures due to its different radiator placement, but the H7 Flow almost caught it when we removed the exhaust filter from our configuration.This mid-tower is perfect for a minimalist build while keeping the process simple and intuitive, utilizing widened channels, hooks, straps, and toolless entry. 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. NZXT can fix the H7 with some tweaks that fall far short of an overhaul but right now they still have work to do. Then, our testing of GPU thermals. The HAF 500 fed our GPU the coolest air, followed by the H7 Flow without the top exhaust filter fitted in place, and then the H7 Flow with top exhaust filter... The graphics card temperatures saw the Elite's multiple front fans offer the lowest temperature of 71 degrees, followed by the H7 flow and the H7 was 4 degrees warmer due it having just one fan. Conclusions

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. 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. 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. 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. 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...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. 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.
