2. Fractal Design Define R6
- Form Factor: Mid-tower
- Dimensions:17” x 18.03” x 21.3”
- Motherboard Support: E-ATX, ATX, Micro-ATX, Mini-ITX
- Weight:4 kg
- Front I/O: 2 x USB 3.0, 1 x USB 3.1 Gen 2 (Type-C) 2 x USB 2.0. 2 x 3.5mm HD Audio
Fractal Design is praised for using high-quality materials and logical layouts on their computer cases, and the Define R6 is no exception. Sure it’s a few years old at this point, but the chassis remains one of the quietest PC cases with its sound-dampening features.
The Fractal Design Define R6 sees good use of steel, aluminum, and plastic all around, which is what we always have come to expect from the brand and its Define family of cases. Like the Silent Base 802, you can buy this case in black or white color with either a solid side panel or a glass window depending on your priorities. Despite its excellent build quality, some may find the squared-off design a bit dull and dated. However, looks are a subjective matter.
This spacious, mid-tower chassis accommodates up to an E-ATX motherboard and has enough clearance for a beefy CPU cooler and GPU. It has ample space for six 2.5”/3.5” hard disks and solid-state drives. It also has nine expansion slots for your graphics card (with support for a vertical GPU mount) and other PCIe devices.
The case layout allows for the installation of up to nine fans, with three 120mm or two 140mm fans at the front and top, two 120/140mm at the bottom, and a single 120/140mm at the rear. Water-cooling options are also versatile, with up to a 360mm radiator on the front, 420mm on the top, and 280mm on the bottom.
It’s worth noting that the Define R6 already comes with two 140mm Dynamic X2 GP-14 intake fans pre-installed at the front and one more exhaust fan at the rear. The retail fans operate at near-silent noise levels and are optimized for this case to provide the best possible airflow. As a bonus, the Define R6 gets you a Nexus+ Smart Hub that offers motherboard RPM controls for six additional case fans.
Aside from the chassis’ extensive modularity, the Define R6 uses highly dense sound-dampening material on the side, top, and front panels. It gives users the option to go for maximum noise encapsulation without hampering the airflow too much. There are also big dust filters on the top and bottom that allow for easy cleaning.
If you are looking for a silent PC case that you would keep in a noise-sensitive workplace, the Fractal Design Define R6 is an ideal choice. Although its design can seem a bit bland to some, it will barely make any noise once you fit all your components inside.

3. Cooler Master Silencio S600
- Form Factor: Mid-tower
- Dimensions:8” x 8.2” x 18.5”
- Motherboard Support: ATX, Micro-ATX, Mini-ITX
- Weight:7 kg
- Front I/O: 2 x USB 3.0, 1 x SD Card Reader, 1 x 4-Pole 3.5mm Audio
The Silencio lineup of PC cases from Cooler Master is known for silence operation, thermal efficiency, and industrial looks. The Silencio S600 continues the tradition with its minimalistic, fine-tuned design to minimize noise levels while also maintaining lower system temperatures.
Like the previous two quiet computer cases, the Silencio S600 is available with two types of side panels: sound-dampened steel for silent operation or seamless tempered glass for showing your build. Everything else remains the same across both variants.
From the outside, the Silencio S600 looks like a simple mid-tower case. However, the inside is where Cooler Master has shown its intelligent engineering by meticulously placing high-quality sound dampening material (e.g., thick foam and mass-loaded vinyl) behind the outer panels. It helps drown the noise coming from the fans, power supply unit, motherboard, graphics card, and mechanical hard drives.
Usually, cases with a non-mesh front cover severely hamper the airflow, but the Silencio S600 keeps your system cool with its clever airflow-friendly design. You can replace the sound dampening cover on the top panel with the included dust filter to increase chassis airflow or keep it in place to minimize noise levels. Behind the solid steel front panel features a recurved vent that directs air in through either side of the front panel. The addition of magnets and rubber stompers around the structure also prevents vibrations.
Not only that, but the Silencio S600 also offers generous clearance space for your computer hardware. It has room for up to an ATX size mobo, along with four 3.5” HDDs and five 2.5” SSDs. You can fit up to a 167mm tall CPU cooler (166mm on the tempered glass version) and a 398mm long graphics card inside this chassis.
The case also demonstrates great potential in terms of cooling, with support for two 120/140mm fans or up to a 280mm radiator at the front, two 120/140mm fans or a 240mm radiator at the top, and a single 120mm fan at the rear. Fortunately, the S600 comes with two Cooler Master 120mm Silencio FP fans, featuring specially designed blades for both quiet operation and high airflow. There’s rubber padding in place to reduce vibration from the fan as well.
Whether you are configuring a PC build for optimum silence or unhindered performance, the Cooler Master Silencio S600 can embellish every type of setup. It’s also cheaper than the first two options on this list and still comes with two high-quality 120mm fans, making it a value-for-money choice.

[/su_table]
[su_button url=”https://www.amazon.com/gp/product/B07SWXBZLN/ref=as_li_tl?ie=UTF8&tag=gekbuzz-20&camp=1789&creative=9325&linkCode=as2&creativeASIN=B07SWXBZLN&linkId=f1e778474df883bfe2c9bb407c0b84d1″ target=”blank” background=”#FF0000″ size=”5″ rel=”nofollow”]View on Amazon[/su_button]
If you want something more compact, the Silencio S400 mATX case is an excellent option. It’s basically a mini-tower version of its bigger sibling, the Silencio S600. Of course, the clearance inside the chassis is vastly different due to its smaller size.
4. Antec P101 Silent
- Form Factor: Mid-tower
- Dimensions:75” x 9.13” x 19.92”
- Motherboard Support: E-ATX, ATX, Micro-ATX, Mini-ITX
- Weight:82 kg
- Front I/O: 2 x USB 3.0, 2 x USB 2.0, 2 x 3.5mm Audio
The P101 Silent is currently one of the best PC cases from Antec simply because it checks almost all the boxes in terms of looks, thermals, acoustics, and comes at a reasonable price.
It’s a black mid-tower enclosure with a minimal asymmetric design and uses thick sound-dampening foams for the side, top, and front panels to maximize low noise operation at all times. The front cover is a solid piece, but there are air channels on its left side for the three pre-installed 140mm fans to move fresh air into the case. There’s a mesh filter that protects the front-mounted fans from dust, along with a second one underneath the power supply fan opening.
The top side of the panel doesn’t have any sort of ventilation going on. It’s also where the I/O resides, with four LED-illuminated USB (2 x 3.0, 2 x 2.0) ports, 3.5mm audio and microphone jacks, power and reset buttons, and a dedicated fan controller slider.
On the rear side of the Antec P101, we find another 140mm fan that acts as an exhaust, bringing the total number of fans included with this chassis to four. All four fans can be controlled via the case’s built-in fan controller, letting you choose between low, high, and zero RPM modes.
Both of the solid side panels offer toolless removal, exposing the white motherboard tray that holds up to an E-ATX size board. There’s plenty of room at the back with routing holes for cable management, and a tray for two 2.5” drives. Speaking of storage, there are four drive bays situated right behind the front fan mounts that can take up to eight 3.5” hard drives, as well as a 5.25” cage at the very top for an optical disk drive.
Fortunately, there’s enough space between the bays and the front of the chassis to fit in a thin 360mm radiator. However, the front drive cages are completely removable, which allows for the installation of up to 450mm long GPU and other PCIe expansion cards. Not to mention, the eight expansion slot covers on the rear are reusable.
For a chassis that comes in a sub-$100 price range, the Antec P101 Silent defines the budget-friendly territory in the market of quiet PC cases. The fact that it gives you four 140mm fans right out of the box is just plain impressive, even though they don’t support smart RPM controls via the motherboard BIOS.

5. Corsair Carbide 275Q Quiet PC Case
- Form Factor: Mid-tower
- Dimensions:11” x 8.3” x 17.91”
- Motherboard Support: ATX, Micro-ATX, Mini-ITX
- Weight:08 kg
- Front I/O: 2 x USB 3.0, 2 x 3.5mm Audio
If you are looking for the quietest computer case on a budget, the Corsair Carbide 275Q is probably the way to go. It’s a mid-tower chassis with Corsair’s signature minimal design, and it comes with all the basic features you will ever need in a PC case. The “Q” suffix in the name stands for “Quiet,” so expect great acoustic performance from this case.
Unlike the original version, the Carbide 275Q features sound-absorbing pads along the inner walls of its steel side panels, which deadens the noise coming out of your hardware. The removable top cover also uses the same damping material, but you can remove it to allow for better airflow. The case even has two dust filters on the front and floor.
Everything else is similar to the original chassis, including mounting points for up to six 120mm cooling fans (three on the front, two on the top, and one on the back). You can also install a 280/360mm liquid cooling radiator on the front and a 240mm unit on the top. It’s worth noting that the case includes two 120mm PWM fans and a 6-channel fan controller, which lets you connect up to six fans to a single 4-pin PWM header on your motherboard and adjust the fan’s RPM from the UEFI. There’s also a white accent LED at the bottom illuminating your desk surface.
For storage, you get a drive bay next to the power supply space for two 3.5” hard drives and rear-mounted trays for up to four additional 2.5” SSDs. The interior of this chassis has enough room for a beefy tower cooler (up to 170mm in height), a large power supply (up to 180mm in length), and a multi-slot graphics card (max 370mm in length).
For such an affordable price, the Corsair Carbide 275Q with its minimal design and noise-reducing elements should appeal to most budget PC builders out there. No side vents along the front mean slightly worse thermals, but there isn’t really much to complain about given how cheap it is compared to every other silent PC case on this list.

Frequently Asked Questions (F.A.Q)
Q1. How to choose a quiet PC case?
When shopping for a quiet PC case, make sure to check whether it uses noise-dampening materials or not. Secondly, if a case is available with either a solid panel or a tempered glass window, we strongly recommend going with the first choice for the best noise absorption as glass tends to vibrate more than dense metal.
Some high-end units come with specially optimized fans that move cool air through the case while operating at near-silent noise levels. However, if you want the best possible acoustic and thermal performance out of a quiet PC case, you will have to invest extra on a couple of heavy-duty Noctua fans.
Q2. What’s the quietest computer case for a small-form-factor PC?
There aren’t many mini-ITX PC cases known for whisper-quiet noise levels. The smallest one we could find is the Fractal Design Define Nano S, which has seen positive reception from various tech media outlets for its compatibility with high-end components and superior sound dampening elements.
If you are searching for a silent mATX case for your compact PC build, the Define Mini C from Fractal Design or the Silencio S400 from Cooler Master is worth checking out.
Q3. Which CPU cooler is ideal to pair with a quiet PC case?
If you don’t want any extra fans running inside your PC other than the front intake and exhaust ones, a passive CPU cooler like the Noctua NH-P1 or the Arctic Alpine 12 Passive should fulfill your requirements. However, before you immediately place an order, make sure that the silent PC case you have selected has enough clearance for such large and beefy CPU coolers.
If you want to go the all-in-one liquid cooler route, check out the below options. Once again, make sure to verify your case’s radiator support before you buy one.
