A New Best: Fractal Meshify 3 Case Review, Thermal Benchmarks, & Noise
Fractal’s has added some interesting new features: an air guide in front of the PSU shroud that genuinely helps GPU thermals in our testing, excellent cable aligner clips, and a bizarre PSU filter that blends seamlessly into the side of the case.
This case was going to launch months ago, but was quietly pulled from shelves by Fractal at the last minute because the PCIe slots were too tight.
Multiple reviewers, including us, noticed that these PCIe slots were too tight for GPUs to slot properly, an issue we had recorded in our notes for the review and were about to film when Fractal sent an email that it was halting the launch. Fractal manually reworked this, meaning someone went through all the cases and shaved them down.
Originally, Fractal would have launched just before the worst of the tariffs, but now is launching into a far more expensive import situation. Fractal says that, for now, its MSRP is unchanged.
But we’re here to review the case. We have a 3-hour documentary about the tariffs’ impact.
The case comes with 3 fans and clearly has a focus on looks with its lighting and front panel design, but also manages to make a number of mechanical choices that affect cooling.
Let’s get into the Meshify 3 review.
Meshify 3 Ambience Pro RGB Overview
This is Fractal’s third generation of Meshify cases, starting with the Meshify 3 and the larger Meshify 3 XL. We’re reviewing the shallow front-to-back Meshify 3 today, which is the size equivalent of the first generation’s Meshify C and the second generation’s Meshify 2 Compact (watch our review). The Meshify C (watch our review) was $90 at launch in 2017, followed later by the Meshify 2 (watch our review) at $110.
The Meshify 3 is launching from $140-$220 (depending on SKU). It’s not distant from Fractal’s Torrent case. We liked that case. It’s priced at around $190 to $230. The increased Meshify series cost goes towards new features.
The flashiest new feature is the “integrated atmospheric lighting” in the top-tier Ambience Pro RGB SKU. Fractal also has committed to proprietary connectors for these cases, which we’re not thrilled about. Fractal additionally has a web tool for the new Adjust Pro fan and RGB hub.
The cases are sold at $140 for 3x 140mm fans without LEDs, $160 for 3x 14mm RGB fans using proprietary connectors, and $220 for 3x RGB fans with a lighting control hub and additional case lighting around the front panel, shroud, and power button.

The Build
Let’s get into the build quality and features.
Some of the exterior is similar to the Torrent, especially the way the top panel slides off. Unlike the Torrent, the top panel is mesh in the Meshify 3, although only the central portion is actually open due to the thick plastic frame underneath.
The front panel pops off from the bottom like the North cases, and the top edge (in the Ambience Pro RGB) has pogo pins to connect the ambient front panel lighting.
There are three plastic “cable aligners” that can be snapped over the main cable channel. We found them to be well-placed and surprisingly sturdy even with large bundles of power supply cables wedged behind them. Our only complaint is that they’re keyed for no discernible reason other than preventing users from flipping the Fractal logo upside-down. The cable management space behind the motherboard is a uniform depth at just over 3cm across the entire case.
There’s a massive cutout above the motherboard that runs its entire length, although the cutout at the bottom is undersized and difficult to use when an ATX board is installed. Overall, cable management is above average thanks to the cable aligners and the amount of space, with some velcro straps on the back for exterior cable management.
The PSU shroud terminates in a plastic “air guide” angled up towards the GPU.
It reminds us a little of the NZXT toilet bowl fan from the 2022 H5 Flow (watch our review), but more so the extremely similar “PSU optional cover plate” from Corsair’s old 5000D Airflow (watch our review). The 5000D Airflow’s single intake fan wasn’t positioned to make that part matter, though, whereas the Meshify 3’s intake-heavy configuration will actually benefit.
The only discrete dust filter in the case is for the PSU. It ejects from the side, which is always a plus for ease of removal, but it’s also built into the leg of the case so that there’s no externally visible handle. This is completely unnecessary, but it’s one of those small features that shows the care that was put into the case’s appearance and great attention to detail.
Drives can be mounted to a set of adjustable brackets behind the motherboard tray; Fractal has provided a complicated compatibility matrix, but basically, you can either fit up to 2x 3.5″ drives or 4x 2.5″ drives. An additional 2x 2.5″ drives can be attached directly to the floor of the case underneath the air guide, but if you use those slots, you may want to leave the air guide out to make cables accessible.
The front of the case can fit either 3x 120mm fans or 3x 140mm fans. The rails rotate to switch between the two sizes and there are cutouts at specific heights for each individual fan, which means the rails don’t obstruct the fans at all, but also there’s little freedom to reposition fans or mix and match different sizes.
All Meshify 3 SKUs ship with three front fans preinstalled, so this is less of an issue than it would be on a bare chassis. When fans are installed on the rails, the fans and rails can be removed as a single unit by undoing two screws, which is awesome.
The removable top bracket is extremely easy to work with and fits radiators up to 280mm with plenty of room. Simultaneously installing a 360mm radiator at the front of the case would technically be possible using standard 30mm thick rads, but without much room left for fittings, fans, or thicker radiators, so we don’t recommend it. Fractal notes that the front mount is compatible with 360mm (3×120) radiators of up to 420mm total length with the air guide or 445mm without it. Critically though, this does not mean support for 420mm (3×140) radiators.
If any radiators are installed at the front of the case, the cable bar has to be shifted back, which makes it harder to route power cables. In addition, maximum GPU length in the Meshify 3 is already only 349mm, and installing a front radiator directly eats that clearance. We recommend relying on the top radiator slot or moving up to the Meshify 3 XL if you really need space for liquid cooling and especially for longer cards.
Along the same lines, Fractal claims compatibility with so-called E-ATX boards up to 277mm wide, but that describes the maximum size that can be installed without completely blocking cable cutouts. Realistically, if you want to install anything even slightly larger than ATX, you should be looking at the Meshify 3 XL instead. Even with a normal ATX board, we shifted the cable bar all the way forward to leave space for the 24-pin power cable.
As a finer detail point, we’re happy to see that Fractal has finally compromised by adding screw holes to the plastic tabs on the side panels. If you want to add some extra security while moving your case, you can put screws through the tabs to lock them down.
The fans and LEDs are complicated and confusing, so that’ll require a whole section — but we’ll get into the thermal testing first.
Meshify 3 Ambience Pro RGB Thermals
Fractal’s review guide claims that the RGB fans are quieter, lower CFM, but higher static pressure (at max speed) than the non-RGB versions of the same fans.
Our thermal results with the stock fans are representative of the RGB case SKUs, though any major physical reasons for performance would still be reflected. The standardized fan test is representative of the Meshify 3 in general.
For reasons we’ll explain in the fan control section, we had no way to skip the fan hub and connect the fans directly to the motherboard as we usually would for testing. We validated that the fans reached their rated max speed of 1,800RPM +/- 10% with a laser tachometer. However, the tach signal sent back by the Fractal Adjust Pro hub doesn’t line up with standard 4-pole fan behavior: HWiNFO misreports 2295 RPM when the fans are really spinning at just over 1,800 RPM in reality. Fractal’s software accounts for this and reports RPM accurately.
As for comparison cases, we’ll mostly focus on the Antec C8 ARGB (read our review) and Antec Flux Pro (read our review) as close matches. The closest match in appearance and function may be Fractal’s own Torrent Compact RGB. We haven’t added the Torrent Compact back to our charts since our testing overhaul, but in our review, it performed similarly to the larger original Torrent. That is in our charts, so we can use that as a rough equivalent.
We have plenty of other cases on the charts for your own comparisons. Let’s get into the data.
CPU Full Load Thermals – Noise-Normalized
We’ll start with noise-normalized thermals. We use our hemi-anechoic chamber that we spent $250,000 building for validating the noise levels, which allows us to heavily control the noise floor and get super accurate capture.
This is the chart. The Fractal Meshify 3 dominates here, planting itself as the new chart leader and within error of the prior leaders. The Meshify 3’s all-core average of 40 degrees Celsius over ambient and 44 degrees for the P-cores is significantly better than previous efforts from the Meshify 2 Compact (watch our review) at 48 degrees average and the Meshify C at 54. Those two cases shared a basic design. The Meshify 3 is more of a departure; Fractal has added an airflow guide to the bottom of the case, the stock fans are higher performance, and all three stock fans are installed in the front of the case.
That’s an arrangement that’s worked well for CPU cooling in the North XL (read our review) and Torrent using our test bench, and evidently it works extremely well in the Meshify 3, which is now the coolest case on the chart. The Torrent was a little warmer than the Meshify 3 at 42 degrees above ambient, while the Meshify 3 is instead tied with the previous best results from the Lian Li Lancool 216 (watch our review) and Lancool 207 (read our review). The Antec Flux Pro is a case that Fractal is likely specifically targeting for competition and, like the Lian Li cases, it’s within one degree of the Meshify 3. This test is a weak point for the Antec C8 ARGB, which averaged 50 degrees due to its bottom intake layout.
GPU Full Load Thermals – Noise-Normalized
Here’s the chart for GPU thermals when noise-normalized.
GPU cooling performance in the Meshify 3 was also strong. The equivalent cases from the previous Meshify generations didn’t have particularly strong stock performance, with the Meshify 2 Compact averaging 52 degrees above ambient for the GPU and the Meshify C averaging 57. This is still noise-normalized, so it’s not purely a matter of more powerful fans in the Meshify 3, which averaged 43 degrees for the GPU and 46 for the GPU memory.
Judging by the performance of the North XL and the Torrent here, it seems possible that the Meshify 3’s air guide actually does do something. The North XL and its conventional (although ventilated) full-length PSU shroud averaged 44-45 degrees for the GPU depending on the chosen side panel, while the Torrent with its top-mounted PSU and complete lack of a shroud at the bottom of the case averaged 40 degrees. The Meshify 3 with its shroud and air guide averaged 43 degrees, right in the middle. There are more variables at work here, though, so we need another test to know for sure.
As for the other highlighted competitors, the Antec C8 ARGB averaged 42 degrees and the Flux Pro averaged 41. Technically they both beat the Meshify 3’s 43 degree average, but they’re all among the best performing results on this chart.
GPU Full Load Thermals – Full Speed
As part of our full speed testing, we ran a test pass with a cardboard box extension taped onto the end of the PSU shroud to bring it up flush with the front intake fans. This test is at full speed case fans and controlled CPU and GPU fans.
Without this extension, the GPU in the Meshify 3 averaged 41 degrees above ambient versus 45 degrees with it. That’s a significant increase with the extension, and it shows that it made sense to shorten the shroud and angle it up like a skate ramp. Adding the extension also raised noise levels from a baseline of 37.5 dBA to 38.7 dBA, which we can only really confidently state is a real difference because of our investments in the hemi-anechoic chamber and our test equipment. This is a real change. Although hardly a detectable difference to the human ear, it is a real one and some people might notice it. Fractal’s new shroud design is superior to a square-edge one both thermally and acoustically.
Since we’ve already seen that the Meshify 3 outperforms its predecessors when noise-normalized, it’s no surprise at all that it outperforms them when its 1,800 RPM stock fans are maxed out. 37.5 dBA for the Meshify 3 is definitely louder than the 31-32 dBA levels from the Meshify C and Meshify 2 Compact, but thermal performance isn’t even close, with the Meshify C only able to maintain GPU temperatures at 56 degrees above ambient.
The C8 ARGB tied the Meshify 3’s GPU temperature in this test, which is impressive for the Meshify 3 given that the C8 ARGB has bottom intake fans pointed directly into the GPU. The stock Flux Pro and Torrent remain chart toppers at 38 degrees and 39 degrees respectively thanks to their overkill stock fans; this is also evident from the noise levels, with the Torrent’s powerful fans pushing it to a maximum of 42.3 dBA to the stock Meshify 3’s 37.5 dBA.
GPU Full Load Thermals – Standardized Fans
Standardized fan testing is next.
All of the Meshify 3 SKUs ship with fans, so we’re just going to use the standardized fan test as an opportunity to compare directly against the previous Meshify generations when they have the same loadout.
The Meshify 3 has three defined 140mm fan mounting locations at the front, so rather than sticking our two 140mm intake fans somewhere in the middle, we were forced to pick either the upper two slots or the lower two.
The Meshify C and Meshify 2 Compact both had GPU averages of 47 degrees above ambient, while the Meshify 3 literally bookended the chart at 41 degrees with the fans in the lower slots and 53 degrees in the upper ones. If you alter the stock fan configuration, be sure to at least keep one fan in the bottom slot at the front of the case.
CPU Full Load Thermals – Standardized Fans
On to CPU thermals while using standardized fans: There wasn’t much difference in CPU thermals between the upper and lower slot tests; although the upper slot technically did better with an all-core average of 39 degrees, the lower slot arrangement is preferable due to the GPU thermals we just discussed. The Meshify C and Meshify 2 Compact tied at 41 degrees all-core, not that far from the Meshify 3’s 40 degree average.
VRM & RAM Full Load Thermals – Noise-Normalized
Returning to the noise-normalized results, the Meshify 3 tied the Flux Pro for the best VRM temperature on the chart at 27 degrees above ambient. That’s significantly better than its predecessors at 35 degrees for the Meshify 2 Compact and 39 for the Meshify C. The Torrent averaged 29 degrees and the C8 ARGB with its bottom intake layout averaged 33. The ventilated case roof and airflow definitely help here.
The SPD hub (or the RAM temperature average) was better, with the Meshify 3’s average of 20 degrees above ambient beating all other stock case results on the chart. The Torrent at 21 degrees and Flux Pro at 22 were also high performers, while the C8 ARGB’s more GPU-focused cooling left it with a warmer 24 degree average.
Fans and LEDs
And now we’re back to the topic of fans and LEDs.
The Momentum RGB fans connect through daisy-chained USB Type-C connectors. Fractal describes the connector as “Proprietary USB-C,” meaning that the connectors are just USB-shaped out of convenience; the fans are NOT USB devices.
This part confused us, so here’s a breakdown:
- The regular Meshify 3’s fans use regular 4-pin PWM fan connectors
- The Meshify 3 RGB’s fans use Fractal proprietary connectors, but they’re pre-routed with an adapter that terminates in a regular 4-pin fan connector and a 3-pin ARGB connector, so the fans can be connected to a normal motherboard out-of-the-box
- The Meshify 3 Ambience Pro RGB has the same fans as the other RGB SKU, but they’re pre-routed to Fractal’s Adjust Pro hub. A “legacy splitter” cable is included for OUTput so that regular ARGB devices can be daisy-chained onto Fractal’s devices, but the INput adapter cable from the Meshify 3 RGB is not included. In other words, if you get the Ambience Pro RGB, you’re using the hub (or waiting for Fractal to sell an adapter cable separately)
The Adjust Pro Hub can be controlled through a web tool or Microsoft’s Dynamic Lighting feature. Fractal can get away with using a simple web app because the Pro Hub is just a USB device, so it doesn’t need low-level access to control the motherboard’s fan and RGB headers. There’s no launch-on-startup bloatware and the settings are saved locally to the hub. Currently, the app claims to be fully compatible with Chrome, Opera, and Edge (but not Firefox). A sustained internet connection isn’t required for this. We were glad to see Dynamic Lighting compatibility, even if it’s not perfect. For instance, if you enable Dynamic Lighting, it breaks Fractal’s tool, and if you haven’t activated Windows then you can’t disable Dynamic Lighting without editing the registry.
Fractal’s software has a selection of prefab lighting patterns to show off the gen 2 lighting, but the default Northern Lights pattern may be our favorite. The indirect lighting around the edges of the front panel and across the PSU shroud are mostly striking in a dark room. It’s unfortunate that such a big part of the case’s appeal is limited to the $220 version.
Meshify 3 Ambience Pro RGB Conclusion
We like the Meshify 3 overall, but we’re torn on several points.
As an immediate positive, as reviewers who don’t normally comment a whole lot about looks, we do think they did well to pull off the LEDs and front panel on the Meshify 3. Fractal has consistently done well to execute on this style.
As for the more difficult points: First off, the Meshify C launched at $90 and the Meshify 2 Compact at $110. Those weren’t the lowest prices in context. The Meshify C, however, was on the affordable end of the scale even for that time. Given that Fractal picked the Meshify 3 MSRPs well before the new tariffs, we believe there’s a good chance they’ll go up. The Meshify 3 isn’t in the medium-budget tier you might assume based on the history of the series. If you’re looking for cases in that vein, Lian Li has options like the Lancool 217 (watch our coverage), while Antec has some equivalents to the Meshify 3 RGB like the C8 ARGB and Flux Pro.
That’s not to say that the Meshify 3 isn’t worth the money, just that it’s embattled on all sides. There are a lot of options in this price category, which is good for consumers. The build quality is on par with what we expect from Fractal based on the last few years’ worth of cases like the North (watch our review) and Torrent. It’s built well. Thermal performance was extremely good, and although the specs are different for the non-RGB fans as we’ve explained, we can assume that the performance is also extremely good for the non-RGB case variants. Based on that, the $140 and $160 options are the most competitive.
As for the $220 Ambience Pro RGB, it’s basically a $60-$80 upcharge for lighting, but we really like that lighting. That is, however, a big price jump. If you’re considering the Ambience Pro RGB with the extra cost for the lighting, you should be comparing it to other flagship showy cases like the HAVN HS420 (read our review) or HYTE Y70 (read our review) (if you can buy one as they can be difficult to find in the US due to the tariffs). You should also look through Fractal’s documentation carefully to make sure you like the RGB ecosystem of software and connectors before you commit.
You can check out the competition like the Flux Pro, C8, and Corsair’s FRAME 4000D (read our review). We have more reviews coming up, but overall, we like Fractal’s new case.
