Best Overall Airflow Case – PHANTEKS Eclipse P500A

Phanteks had some great performers focused on airflow in the P300A and the P400A. Now they have charged the market with an even bigger case – the Eclipse P500A. It has muted styling and stealthy design. It has room for flexibility: with an optional $20 mount, you can install a second mITX system, like some streamers prefer to do. It is about mid-range, shipping at $100 for the regular version, and $130 for the DRGB one.

The size of the chassis is quite large, but the P500A uses it excellently. Airflow is, obviously, a big win in this case. But the interior utility and ease of cable management is nothing to scoff at, either. Build quality is excellent, and the swivel TG door is fantastic. If you get the RGB model, the front fans show off cool effects that’ll keep you in a trance. It is not the quietest but gets the job done.

The downside of this PC case is perhaps its size. This is quite a large mid-tower. And, if you are not using the second system option, then maybe it is simply too large for comfort. And depending on your preference, the design might look a bit also focused on utility.

The bottom line is that there are no compromises to be made with the Phanteks P500A. For a reasonable price, you are getting a fantastic piece of hardware. And it has one of the best airflow performances in the closed mid-tower category. This PC case is a no-brainer.

Best ATX Airflow Case – Lian Li Lancool II Mesh (Performance)

We’d suggest you opt for the ‘Performance’ model. It comes with a duo of 140 mm PWM fans and a fan controller. This combo seems to us like a better deal than the 3 120 mm RGB fans alternative. Almost every single detail of this case is engineered to near-perfection. The dual TG panels look great. The bottom side panel being mesh now allows for significant air to be drawn in by bottom fans. The internal is reasonably spacious, and you can fit a whopping nine drives inside this case. Airflow is, above all, superior to anything Lian Li has put out previously.

One reason it loses favor compared to the P500A is that USB-C support is optional, aka you need to shell out more money for it. We understand this is meant to be a cost-cutting move, but most consumers will appreciate the inclusion of USB-C, so this option is simply a hassle. Just put it in, Lian Li. Another downer may be the somewhat bland design, similar to its predecessor. If you want a case that looks just as good as it performs, look further down our list.

That one nitpicks aside; you really cannot go wrong with this case. Its performance is top-notch, and Lian Li is known for its stellar build quality. For the price, you are getting so many features and such a flexible interior. Among normal ATX mid-towers, the Lancool II Mesh sets the bar.

Best Budget Airflow Case – Fractal Design Focus G

The Fractal Design Focus G is definitely our top pick for budget users. In addition to being the cheapest option on this list, it also comes bundled with two great intake fans out of the box, though you’ll need to add your own exhaust fan to the setup.

The Focus G offers reasonably-compact size (especially with the Mini version), a builder-friendly interior, and most importantly for airflow, a full mesh front panel. This mesh front panel allows for superb air intake into the PC, especially if you utilize both of the available intake fan slots. Elsewhere in the chassis, you also have room to mount an extra bottom intake and top exhausts.

The only real downside of this case that we can think of is its side panel window, which is made of Acrylic instead of Tempered Glass. This is a minor nitpick, though, and won’t have any kind of impact on the thermal performance of your components inside of this rig.

If you want great airflow but can’t afford the higher-end cases on this list, then the Focus G should be perfectly suited for your needs. If you want to do a smaller Micro ATX build instead, you can also opt for either the Focus G Mini or Meshify C Mini linked below.

Best Mid-Range Airflow Case – Silverstone Redline RL06

Let’s just get this out of the way: according to third-party reviews, the Silverstone Redline RL06 offers among the best, if not the best, airflow of any case on the market. Knowing what we know about front panels now, it’s easy to see why: not only is the front panel mesh, it is huge, and it leads very directly into the three provided intake fans.

This case is focused on providing superb airflow above all else, and it shows. In addition to the three included intake fans, you also have an included exhaust fan pre-installed in the back. While you will spend more for this than the Focus G, you won’t need to worry about buying any extra fans: out of the box, this one is already a positive pressure powerhouse.

In addition to the great airflow, you have extremely spacious internals to work within, including a dedicated PSU basement, with cable management and drive mounting in the back. This is a very clean-looking case, aesthetically-speaking, and a superb performer on top of that. We highly, highly recommend it.

Best High-End Airflow Case – Cooler Master MasterCase H500M

Last but not least, though..we know some of you won’t be satisfied with anything less than the most superb RGB implementation.

The Cooler Master MasterCase H500M (as well as the stock H500), offer dual 200 mm RGB fans for truly superb air intake and gorgeous RGB aesthetics. If the main selling point you need to hear is “it has RGB”, congratulations: it has RGB, and great thermals. What’s not to love?

Well…the price point. Despite mostly being the same case as the H500 (which is available for roughly half the price), getting addressable RGB fans adds a significant price premium. The difference between regular RGB and addressable RGB is the ability to address individual LEDs inside the RGB device, whereas plain RGB can only address the entire device. Addressable allows for even deeper customization of your RGB lighting, but you’ll pay a price for that.

If you don’t care about addressable RGB, feel free to opt for the H500. It’s virtually the same case, just with a less powerful RGB implementation.

RGB and pricing nitpicks aside, this is a truly gorgeous case that performs well…as long as you swap to the included mesh front panel. Both the H500 cases ship with two front panels: a glass front panel, which chokes airflow, and a mesh front panel, which doesn’t. In the context of this article, the choice should be fairly obvious: always go mesh.

The rest of the case is huge, but extremely flexible and builder-friendly. For those of you who want an Extended ATX build, congratulations: this is definitely the case for you.

Best Mini-ITX Case – Sliger SM580

Small form factor (SFF) PC cases is a unique market. It is united by the need for compactness, yet divided in the aim of different products. The Sliger SM580 is not the most compact or best looking ITX case. It does, however, stand out in terms of air and water cooling support. And it has a trick up its sleeve that makes enthusiasts really happy. Starting at $270 for the stock configuration, it is quite expensive.

The interior of this case is a sandwich style layout, recently gaining popularity. The design is very detailed and no single component feels out of place. The space for three-slot GPUs and double-fan AIOs is truly impressive. You can customize not only the color but also the side panel type, front I/O (or forego it altogether), riser cable, PSU cable, optional handle and even HDD brackets and fan adapters. Go for the vented panel, because that setup will provide you with maximum airflow and keep temps low. Get your blower-style graphics card and rest of your build right, and you can extract astonishing performance from something this tiny.

Unfortunately, not every customer wants or needs so many options. The issue of price creep with every component you add is also very real. Price is already so high to begin with. Another issue might be one of compatibility. Certain shaped radiators or fans may not actually fit without some meddling. Be extra careful to check parts of your build agree with each other.

While something like the NZXT H1 gives it a run for the money, that is a specific kit bundling an AIO and PSU that costs even more. For excellent airflow in a small form factor, the Sliger SM580 takes the cake. The price is a bit steep, but the in-depth customization ability redeems this PC case.

Best for Water Cooling Flexibility – Fractal Design Meshify S2

Fractal Design is the brand revered for unmatched user experience. They brought mesh panels to popularity with the Meshify C, making airflow not only a priority for hardcore enthusiasts but for the general consumer as well. The S2 is a scaled up version of the same concept. It has the chassis of the Define R6 and their signature attention-to-detail. It is a bit expensive at around $150.

A huge positive for this case is the immense space it offers. This has two implications. The first, building inside this case is a breeze and all your components fit in nicely. The second is that airflow is not hindered by the constraints of compactness. The numerous accessories and the user guide are also a boon for first-time PC builders. The performance doesn’t just cater to airflow fanatics, however. The radiator support is superb, with up to a 360/280 mm unit at the front, 420/360 mm at the top and even a 280/240 mm at the bottom. There is plenty of space to route pipes easily and even install a custom loop if you’re up for it.

Let’s go into some downers. The price is a bit higher than it needs to be. The mid-tower market has so many worthy rivals that Fractal’s pricing feels a bit off. Also, this case is basically Meshify C + Define R6. While that is not a bad thing necessarily, some effort to innovate would have been nice.

At the end though, the spacious interior and ample airflow in this case defend its place among the great airflow cases. Whether going for an airflow, water-cooled or balanced build, the Meshify S2 is flexible enough to accommodate it all.

Best Open Air Case – Thermaltake Core P3 TG

An open air case is a strange beast. Midway between having your components out in the open and enclosing them within a full frame, open air cases offer a unique sell. By definition, most have airflow unmatched by traditional closed PC cases. The downside to this is the frustrating amount of dust that accumulates from allowing air to pass unmeshed or unfiltered.

If you understand the predicament of open air cases, then the Thermaltake Core P3 is an easy recommendation. Compared to the earlier Core P5, now the company has made things easier for beginners. You can now install an AIO without any DIY. Also, the size is much more manageable and most components are modular. The airflow is not hindered by anything and the case itself does not produce any noise. Mounting options are myriad, both of the case and the components within.

Negatives about this case are few, and there’s nothing in particular to complain about. The thing is, almost all open air cases do things their own way, so comparing them is not really an easy task. For example, Thermaltake’s own core P90 looks really unique. So does InWin’s D-Frame and the Cougar Conquer.

The one big thing that sets the Thermaltake P3 TG is price. At $130, it might seem above mid-tier when compared to mid-towers. But in the open air category, this PC case is well worth the money.

Best Looking Case with Airflow – Cooler Master TD500 Mesh White

Do you want a balance between looks and airflow? Then Cooler Master’s TD500, the mesh white to be particular, might be the product for you. While it seems like the company is inn love with the number 500, this white case looks really great from afar.

The metal mesh front lets in sufficient airflow, which is of course our main concern. There are three pre-installed 120 mm RGB fans there. This is addressable RGB, and a controller is included as well, which is nice. The internals are roomy enough for large GPUs and coolers. The unique thing about this case includes the side TG panel which has an angled look we find alluring.

But, Cooler Master put a plastic piece at the front which is a letdown when you examine the case up close. The flexibility in terms of drives and components is also subpar. And, it does let out a bit of noise, compared to similarly price offerings from be quiet!

All in all, the Cooler Master TD500 Mesh White could cause you to fall in love with it on first sight. If it does, there are no pressing reasons not to get it, at a reasonable price of $100. It may not be the best at performance or utility, but it looks darn good.

Best Cube Case for Airflow – Corsair Carbide Air 540

If you dislike the traditional tower shape of PC cases, then opting for cube cases is a genuine option. While you may not get many alternatives in this category, thankfully there is the Corsair Carbide Air 540 to save the day. A disclaimer first: this is a really old case, seven years old.

While design and layout of the Air 540 might look a bit dated, the airflow is not. The space is well-designed and fits plenty of fans or radiators. The dual-chamber interior houses up to large components easily. Inclusion of toolless design is a plus. The construction quality is also robust. Three excellent 140 mm fans are included as a bonus.

This is, sadly, a noisy case. And among today’s cases, the front I/O looks out of place. The industrial design may put you off, as the market has shifted; now a case is not just a box where you put your PC, but the centerpiece of your build.

If you want a cube case, for any particular reason, and yet want great airflow, pick the Air 540. At the price of $140, it is the best in its class for performance. We do hope Corsair refreshes this product, though, to bring it into the new decade.

All You Need To Know About PC Case Airflow

In this section, we’re going to go through everything that you need to know.

Let’s start with the basics.

What is airflow, exactly, and how does it work?

Airflow in this context refers to the speed and volume at which air flows through your chassis. Generally speaking, you want as much air going through your case as fast as possible, that way the heat generated by your components doesn’t linger and build inside your PC. While a PC could technically work without any intake or exhaust fans, it would also run much hotter and therefore much slower, since the CPU and GPU will throttle themselves to protect from damage.

Good airflow is vital for two reasons:

• Ensuring that your components perform in tip-top shape
• Ensuring that your components have the longest possible life, as higher temperatures degrade hardware faster

The last thing you’d want is for your PC to underperform or for your parts to die quicker than they otherwise would. A proper airflow configuration can also help prevent excessive dust from building up inside your PC, though even with the best airflow and filters, dust is still inevitable over time.

Difference between Positive and Negative Air Pressure

Now, let’s talk pressure. This is actually fairly important to consider when balancing a case for proper airflow, as it can make a massive difference in how everything works out. Depending on whether you’re running a Negative or Positive pressure configuration inside your PC, the exact same chassis with the exact same number of fans can experience fairly different results.

Allow us to explain.

Negative Pressure

Negative pressure refers to when there is more air being exhausted than air being taken in. For a particularly extreme example, this could refer to a PC where all fans are on exhaust instead of intake duty, but most won’t make this mistake.

Negative pressure results in a lack of cool air being created inside the case and excess dust being pulled in from outside of the chassis. This is because all of the fans present are working against each other and pushing the same hot air just outside of the PC, where it’s likely to return very quickly due to the negative air pressure inside of the chassis.

As you’ve probably figured out by now, negative pressure is definitely not what we’re looking for. So what about positive pressure?

Positive Pressure

Positive pressure is when more air is being taken in than air is being exhausted. This ensures that the PC is always receiving fresh, cool air, which helps keep components cool…within reason. Without at least one exhaust fan in a positive pressure configuration, you’ll begin noticing similar downsides as with negative pressure. Excess dust will build over your air intakes, and while the case will technically be cooler than with negative pressure, heat will still have difficulty escaping from your chassis.

For these reasons, it’s best to have a balanced-leaning-on-positive air pressure configuration. For every one exhaust fan you have, you’ll want to have one intake (balanced), or 2+ intakes (positive). If you add additional exhaust fans to your chassis, be sure to also add intakes in order to keep the balance leaning toward positive pressure.

If you can avoid it, never allow your exhaust fans to outnumber your intakes.

Fan and radiator mounts

Now, let’s talk mounting fans and radiators.

Fans and liquid cooling radiators alike use the same mounts, and often what you’ll do is mount a radiator to a given space and an additional fan directly to the radiator in order to push air through it and keep the liquid (and therefore the component it’s cooling) cool. We’ll explain this in more detail below.

Fan mounts and sizes

For most PC cases, fan mounts come in one of two sizes: 120 mm and 140 mm. These measurements refer to the length of one of the fan’s four sides.

While 120 mm fans are by far the most popular, 140 mm fans can be fairly useful, too. The main reason to opt for a 140 mm fan over 120 mm is noise, since larger fans can push more air more quietly than smaller fans. In terms of raw airflow performance, however, some of the best fans on the market are still 120 mm: just not necessarily the quietest.

Generally-speaking, you’re going to want at least three fan mounts available in a given PC to accomplish a positive pressure setup, with two fans being used as intake and one being used as exhaust. (This applies especially to Mini ITX PCs.) With larger cases, it’s common to have 3-4 intake fans with 1-2 exhaust fans, which is still a perfectly fine setup for accomplishing positive pressure.

How liquid cooling radiators work

Liquid cooling radiators are measured in mm, but of their longest side. A 120 mm radiator will slot right into a 120 mm fan slot with no issue, but a 240 mm radiator will require two 120 mm fan slots side-by-side in order to be properly mounted. In most situations, it’s best to use a radiator in an intake position rather as an exhaust, since testing shows that CPU temps are massively impacted by configuration whereas GPU temps are not.

Front panel types and what you need for good airflow

Now, let’s talk front panels. For good reason, we’ve gone with one specific type of front panel for all of our main picks, for reasons that will become quickly apparent.

Solid Material (Tempered Glass, Plastic, etc)

Easily the worst for airflow. A solid front panel may look pleasing aesthetically, but unless there are vents elsewhere on the chassis for intake, then your airflow and temps are going to suffer. If airflow and performance are your chief concern, do not buy a case with a solid front panel: at least, not one without ventilation on the sides.

Solid w/ ventilation

Like above, but better. As more users have become aware that solid front panels are bad for airflow and bad airflow is bad for their PCs, manufacturers have started using this to compromise between aesthetics and performance.

In some cases, this can be done by creating a wide gap between the glass and intake fans, usually protected by some sort of dust filter. In others, vents on the side or full-on side fan mounts may be the solution. While these still won’t provide the best thermals, it’s still better than dealing with a fully-solid front panel with no form of air intake.

Perforated metal

An interesting choice, but one becoming more common in recent cases from Corsair and Cooler Master. While this isn’t the highest-performing option, it’s certainly a lot better than having a solid front panel. On the scale from aesthetics to performance, this leans fairly close to performance…though whether or not perforated metal is actually aesthetically pleasing is going to vary from person to person.

Mesh

The best option…short of just pulling off your front panel (which you should not do, unless you want to dust your PC like a madman). Mesh prevents air from being outright blocked in any area, and requires only minimal fan power in order to pull air through. Mesh’s high airflow performance has made it our top choice for the cases we’ve selected today, and third-party testing from sites like GamersNexus confirms it to be the best.

How case size impacts airflow

Case size doesn’t necessarily impact airflow by itself, as we discuss in our Mini ITX case article. However, case size will naturally impact temperatures if proper airflow isn’t in place, since the same amount of heat is being generated in a smaller space. As long as your case has proper ventilation and enough fan mounts (at least three recommended for any Mini ITX/Micro ATX PC build), then you shouldn’t need to worry too much about airflow.

In addition to our main recommendations below (which are for standard ATX builds), we’ve also included a few smaller case picks that still have good airflow. So if you’re worried about getting good airflow but still want a smaller PC, don’t worry: we have you covered.

How many fans you need for good airflow

As we’ve discussed prior, the main thing you need is a positive pressure configuration: at least 2 intake fans per single exhaust fan. 1:1 configurations can be okay too, but are less ideal for keeping temps low and air flowing.

The more room for fans you have in your chassis, the more you’ll benefit from adding fans to it. We recommend mounting as many intake fans as your case can support, and adding a second exhaust fan if that number happens to exceed three. As long as your fans are half-decent and in a positive pressure configuration, you’ll have the best airflow you can get with your chassis.

If you want some great fans for intake and exhaust, we recommend these Noctua fans.

How the CPU and GPU are impacted by airflow

While your CPU and GPU have their own coolers, they still need to be receiving cool air for the best results, especially your CPU. With a positive pressure configuration, ensure that both components are getting the influx of cool air that they need to achieve peak cooling performance. This will also allow them to sustain higher clock speeds for longer periods of time, resulting in a not-insignificant increase in performance.
