How Do Quiet PC Cases Differ From Regular Ones?

Cases with quiet operation in mind generally differ from those with airflow as a priority in a few ways. A quiet PC case will almost always have their panels lined in a noise-deadening material to limit any sounds that can escape.

These panels, and the case in general, may also be made of thicker material to further aid noise deadening.

Front panel air intakes will generally have smaller air passageways, instead of a mesh, to prevent fan noise from being audible. Some designs go as far as to purposely restrict airflow to further lower noise in some cases, at the expense of better airflow.

Hard drive bays will have vibration reduction measures. Fan mounts will sometimes come with rubber grommets to reduce vibration.

If you’re constantly moving your PC around with you, are space-constrained, or just want the smallest desktop PC possible, the mini-ITX form-factor has you covered.

Building in a fully bespoke mini-ITX can be a pain with compatibility, and that’s why The Fractal Design Define Nano S gets our nod for Best mini-ITX choice.

It’s stellar acoustic performance, quality design, and compatibility with full-size parts gives you a compact case that is easier to build in.

As with the other Fractal PC cases on our list, this one’s no exception with its silence. Industrial-grade sound dampening material at the front, and side panels, noise-optimized airflow, and a ModuVent™ removable top cover, and removable and washable nylon dust filters front and bottom are par for the course.

The Define Nano S may be a mini tower, but cooling options certainly aren’t. 6 fan mounts in total, with up to 2x 140mm fans in the front and up top, 1x 120mm rear, and 1x 120mm bottom, airflow is plenty.

Radiator support is there too, with up to a 280mm (max-width 147 mm, max overall length 312 mm) being supported in the front, and a thin 240mm up top should cover your water cooling needs.

Should you want to go the air cooling route, support for up to 162 mm tall coolers give you an adequate range of options.

GPUs with a maximum length of 315 mm are supported, but be careful on width as cards wider than the dual-slot bracket may run into compatibility issues.

What to Look for in a PC Case

Before you go headfirst into purchasing a new PC case, you should take a step back and ask yourself “what do I really need in a case?” You’ll thank yourself later.

Buying the wrong case for the job could end in disappointment, or even worse, your components not fitting properly. Below, we’ll walk you through some fundamentals in choosing what’s right for your application

The Right Size for You

When choosing a case, you have to figure out how big (or small), you want it to be. Size isn’t everything, but you should generally figure out which form factor you want to go with before choosing your respective parts.

Full Tower cases are the biggest of the bunch, and can generally hold any hardware you can fit in them. They are tall, wide, and long, and take up a fair amount of space.

With this size comes support for multiple drive bays, the biggest air coolers, largest AIOs, and multi-radiator custom loops.

They can fit bigger, E-ATX motherboards, with some even offering enough space for multi-CPU boards, and multi-GPU configurations. We’d recommend a Full Tower for very high-end builds.

Mid Tower PC cases are the most popular on the market right now, with a large variety of options to fit your aesthetic and performance needs. They can fit full-size ATX motherboards, most lengthy graphics cards, have impressive storage options, and quality options have support for most AIOs and Air coolers.

They are the best fit for most users as most hardware will fit with no issues, and they are generally more affordable.

Quiet Mid tower PC case that has RGB lighting

Micro-ATX, or m-ATX cases, are the next size down, and are perfect if you’re space constrained, or want a smaller computer. They are built specifically for compatibility with m-ATX or m-ITX motherboards, so keep this in mind if you decide to go this route.

Storage slots, cooler height, AIO support, and graphics card length may be limited, depending on which case you choose.

Finally, we have Mini-ITX or m-ITX cases. They are the smallest of our choices, only support m-ITX boards, and can be the most difficult to build in.

They are popular for HTPC or media-center builds, or for those who move around a lot and like to take their PC with them. While making excellent compact builds, they do come with their limitations.

Hardware support is limited, with the smallest of cases not even supporting full-size coolers, AIOs, graphics cards, or power supplies.

Cable Management

Stray cables can hinder airflow, and don’t do much for looks either, so it’s best to keep them tidy and neat. Most cases have cable management routing behind the motherboard tray, but some cheaper casing don’t, so it’s something to look out for.

More premium quality cases have specific channeling and adequate room for cables, and velcro straps to aid in keeping things clean. Opting for a semi-modular, or fully modular Power Supply can also greatly help since you can choose which cables are needed, and which ones can be left unplugged.

Expansion Slots

Making sure you have enough room for your storage is important. Cases should have their drive bays listed on their spec sheet, and you want to pay attention to this. Something else to look for is tool-less drive bays.

They make installing or changing drives much easier, and most cases nowadays have this feature.

Front panel connectivity shouldn’t be overlooked either. Reaching around to the back of the PC can be difficult, depending on orientation, and having good front panel I/O makes life easier.

Make sure the case of your choosing has enough USB ports to cover your needs and to make sure you get at least some of those in USB 3 flavor since some cheaper computer cases don’t come with USB 3.

Newer cases come with USB Type-C ports, so if you’re looking for USB Type-C connectivity, it’s best to get a case that comes with one.

Figure Out What Components You Want to Use

Sometimes it’s easier to choose your components first, and pick a PC case that fits your needs afterward, instead of choosing your components around a case.

Things like motherboard form factor, graphics card length and size, AIO or air cooler size and length, and the number of drives can all play a factor in what case may be the best fit for you.

Cooling is Crucial

Making sure your components are cooled sufficiently is imperative. Airflow should be prioritized in situations with small cases and high-end, power-hungry hardware.

Cases with mesh fronts can help ease this situation but can sacrifice silence, while cases with tempered glass or restrictive fronts may require more case fans due to limited airflow. Cooler compatibility is also an important consideration.

Smaller Cases are Harder to Build in

Some Mini-ITX cases can be hard to build in due to size constraints. Beginners just starting out may not be aware of all the compatibility issues, and even experienced builders can stumble when trying to fit components into such small and tight mini-ITX chassis.

Compact builds can be great, but just remember that it may take more time, research, and patience to complete than a regular-sized build.

Choose Something That Catches Your Eye

Unless you don’t care about looks, want function over form, or are going to be hiding it out of sight, chances are you’re going to be spending a lot of time seeing your case.

attractive looking PC build

Take the time to find something that you’d enjoy to look at, all day, every day. Whether that be an RGB equipped, tempered glass case, or a simplistic and sleek black metal case, make sure it appeals to you.

Tips on a Quiet PC Build

Below are a handful of tips to help you build a quiet PC.

Water Cooling Isn’t Always Better, and GPUs

AIOs may be attractive, and the best ones on the market undoubtedly provide better performance than their air-cooled counterparts. But sometimes water cooling isn’t the best choice for a silent build.

It can be noisy, as noise from the pump is non-stop, and fans ramping under load can contribute even further to this.

If silence is your priority, you may want to consider a big air cooler instead. The best options, like the Scythe Fuma 2, be Quiet Dark Rock Pro 4, and Noctua NH-D15, come very close to AIO performance, but with the added benefit of whisper silence.

Another consideration is your choice of GPU and it’s cooler. Some models are louder than others, and some heat sink designs perform worse than others.

Ideally, your choice would be a 3-fan model with a well-designed heat sink for near-silent operation even under load. ASUS’ STRIX, EVGA’s FTW3, Gigabyte’s Windforce 3x, Sapphire’s Nitro+, and MSI’s Gaming X Trio cards are all good examples.

Most modern GPUs also have a 0-fan feature that stops fans from spinning while not under heavy load, further reducing noise output.

Airflow Doesn’t Always Have to be Compromised

Having a quiet PC doesn’t mean you have to sacrifice airflow for better acoustic performance. While cases designed with silence in mind won’t be on par with traditional cases, you can get close.

There are cases on the market that are designed to have good airflow while still being silent or have flexible options for varying amounts of silence and airflow. Fractal Design’s Define series is a good example.

PSUs and HDDs

When building a silent PC, don’t overlook your Power Supply. Choosing too low of a wattage for your system can lead to excess strain and heat, causing the fan to spin up.

Another consideration is efficiency (80+ rating), the higher the efficiency, the less power that winds up getting wasted and turned into heat during voltage conversion.

600W power supply

This leads to lower overall temps and the fan spinning up less, or not at all. Some PSUs also have a hybrid fan mode that lets the fan shut off during lower loads.

We’d generally recommend at least an 80+ Gold rated unit that is rated around 40% more than your total system power draw. Some good examples are Corsair’s RMx, be Quiet!’s Straight Power 11, or Seasonic’s PRIME and Snow Silent series.

Hard drives are yet another source of noise, and even the quietest models can be audible once they start spinning. Consider going with a full SSD storage setup, for extra silence.

Fans

Fans can make, or break, a silent build. When choosing fans, you want to take dB rating at speed, size, fan blade design, noise dampening, and bearing type into consideration.

140mm fans are generally quieter than 120mm fans for the reason that they don’t have to spin as fast to achieve the same airflow.

Decibel rating (dB) at a given RPM will also give you a good idea of how well a fan can flow air while still remaining silent. The choice of bearing is also crucial. The best silent fans on the market use Fluid-Dynamic bearings for reduced noise.

Furthermore, silent fans have blade designs intended to reduce turbulence at speed and include anti-vibration mounting, and unique frame designs to further dampen or reduce excess sound. PWM support is important as well for precise speed control.

The best examples of noise optimized fans on the market are Noctua’s NF series, be Quiet!’s Silent Wings series, and Arctic’s F and P series PWM fans. These do a great job in keeping noise levels down.

Frequently Asked Questions (FAQs)

What is the quietest PC case?

There’s no real concrete answer to this one. There are plenty of good quiet cases, but your choice of hardware will ultimately decide how quiet that PC case can be.

Are quiet computer cases good?

If you want near-silent performance, then yes, a quiet computer case is good. HTPCs, music production, games streaming, and live podcasts are good examples of scenarios where you don’t want any excess background noise polluting your environment.

The trade-off, however, can be slightly higher temperatures, so make sure your cooling is adequate.

How can I make my current PC quieter?

Check that all your screws are tight, that your PC case is on a flat surface with all feet firmly planted, and inspect any attachments, grommets, or gaskets that may have come loose or weren’t assembled properly. If your case’s feet aren’t rubberized, you can add your own.

Sound insulation is also an option for cases that didn’t come with it from the factory. You can get insulation, which is usually in the form of foam, fairly easily and cheaply.

This can be put on side panels with adhesive to dampen noise, or to fill extra holes to lessen the amount of sound escaping from your PC case. Just be careful not to hinder airflow too much.

I hope that after reading each review of these awesome cases you have found the one that suits your needs the best.
