Best Quiet PC Cases in 2021

The PC case is one of the most important components when building a PC. You have to make sure that the case can house all of the hardware components you want while providing good airflow to the components inside to keep the components, such as the CPU and the GPU, cool. Obviously, with the fans and the hard disk drives, the PC can and will make noticeable noise, but the manufacturers are trying to keep that noise as low as possible; you certainly don’t want your PC to sound like a jet. This noise can increase under load, and it can be annoying and can divert your focus whether you’re gaming or working, and it can wake those you live with.

At a Glance:

For many years, the manufacturers are constantly trying to improve their products based on user feedback. We have a new trend among the newest trends in the PC cases market, which is a quiet case. These PC cases claiming to be quiet have been around for years, and they have become more popular for a good reason.

Fractal Design Define S

Fractal Design Define S
Fractal Design Define S
Motherboard Compatability:ATX
Dimensions:20.98 x 9.13 x 18.27 inches
Weight:‎18.74 pounds
I/O Ports:2x USB 3.0, Audio in/out
Material:Alloy Steel

The so-called “Extreme” system builders are known for chopping away a few parts of their cases to fit more stuff inside their case. Usually, they get rid of entire drive cages and seal off the external drive bays to make more mounting space and have a cleaner look. Taking a step further, Fractal Design went and removed those parts from their Define S case design entirely. However, the company’s solid shell has built its reputation among some of these same enthusiasts. Fractal Design Define S is not charging their customers to modify the existing case but has instead reduced the cost of bays and cages from the new model’s price.

Let’s have a closer look at the outside of the Fractal Design Define S PC case before we jump into the interior of the case. The Define S features a solid face panel which has replaced Fractal Design’s similar-looking classic noise-dampened door. Just above that, there are two USB 3.0 ports along with a reset button, power button, headphone jack, and microphone jack. Behind these ports are removable outer covers, which allow for full access to the internal top panel. Since the Fractal Design Define S is mainly designed for internal liquid cooling, Fractal Design didn’t need to add portholes for the liquid coolers on the back of the Fractal Design Define S PC case.

This is not considered a weakness of the PC case; some consumers may prefer to see eight expansion slots instead of seven provided. There are dust filters at all intake positions, including the optional bottom fan mount position. The front has a magnetic dust filter, while the bottom one is a slide-in dust filter. Fractal Design uses its cloth-faced asphalt damping sheets and their durable and solid steel sheet work. With so many vents on the left side window, the Fractal Design Define S PC case only has the right panel with enough space for the proper application of those sheets.

Pros

  • Optimized designed for dumping the sound
  • Extensive support for water cooling
  • A dust-free interior with dust filters
  • 2 dynamic fans of fractal design

Cons

  • Only 5 Drive bays
  • Somehow heavy
