Glass Panel or No Panel Case

For a silent PC, glass panels or no panel pc cases both work fine. However, it is also a fact that tempered glass cases have become quite popular additions in recent years, replacing all the acrylic and plastic panels that adorned older offerings.
To simplify, if you like to show off your PC’s internal components or you want to check your PC for dust accumulation, we will recommend a windowed case.
If you still find it too hard to decide between the two, go for the one which you find more aesthetically pleasing. However, keep in mind that glass panels resist noise better than other materials.

SSD over HDD

We will advise you that don’t opt for a standard hard drive, and we have solid reasons. The major difference between a standard hard drive and a solid-state drive is of moving parts. Standard hard drives or HDD include spinning disks that often make noise, especially when you use them under extreme load. On the other hand, SSDs don’t have any moving parts, and therefore SSD provides silent operation and doesn’t make noise even under heavy loads.

Power Supply

When trying to build a silent pc, always opt for a high-spec PSU as they are always important in any machine. Never go too cheap, or else you will only get poor efficiency with excessive noise. Keep in mind that you are not only looking for ‘raw wattage,’ but a high power and efficient unit with a great cooling profile so that your PSU doesn’t get noisy while working.

Keep It Clean

Another vital thing to pay attention to if you really want a silent pc case is cleanliness and maintenance. Your PC can become noisy if any internal component attracts dust or gets loose. In such cases, components will vibrate against the PC’s frame. As PC age, they quickly accumulate dust, hairs, lint, and other similar elements, which can block fans, increasing vibrations and noise.

Quietest PC Case Fans: Noctuna NF-S12A FLX

Fans are an important component of every PC. It keeps your system cool by inhaling and exhausting all the heat produced by the components. This read will talk about the quietest case fans (120mm), the Noctuna NF-S12A, a premium fan that offers super silent cooling for any PC.

You should know that NF-S12A features three variants, the PWM, the FLX, and ULN, but here we are talking about the FLX series that will be ideal for your case. The NF-S12A FLX features constant speed. However, you can adjust its speed. For this purpose, you will need a low noise adapter or ultra-low noise adapter (comes with the purchase) to set or adjust the fan’s speed. Plus, it is the most quiet pc fan amongst the three variants.

Furthermore, the cooling fan features anti-stall knobs along with the innovative acoustic optimization or AAO frame that delivers optimal airflow while keeping the noise level at a minimum.

Quietest CPU Water Cooler: Corsair Hydro Series H115i

What makes a PC Case silent?

You will have to consider various elements when it comes to a silent pc case as these components can impact the noise level quite. Let’s check them in detail below:

CPU Cooling – The latest CPUs are powerhouses and consume a lot of energy and power. This high power consumption demands optimal cooling. Whether you have air cooling or liquid cooling, it should be the best as it impacts noise levels, especially when you overclocked the machine. High heat levels bring more noise, so be cautious.

GPU – Graphics cards are power-hungry components and require effective cooling as it generates a high amount of watts when working. Hence you need an efficient cooling mechanism if you are using a graphic card.

SSD – Always opt for a good SSD unit that provides zero noise output. Plus, SSD’s have no moving parts while HDDs have that make noise while working. Plus, HDDs have fast and high RPMs that make noise while reading/writing. So, avoid using HDD if you want a silent pc.

PSU – A durable PSU also makes your PC quieter. This is because durable PSUs are more efficient, and they also consume less power. High-quality PSUs also have smart fan controls that make the PC a quiet one as the fans will only spin when the unit is under heavy load.

What is a good quiet case fan for PC?

Here are some of the good quiet case fans for your PC that you can use without any issue:

1. Noctua NF-A12 Premium Quiet Fan.
2. Be quiet! Silent Wings 3 Cooling Fan
3. Corsair LL Series LL120 Fan
4. Noctuna NF-S12A FLX
5. Lian Li Uni Fan

Is Water Cooling necessary in a Quiet PC CASE?

Liquid cooling is an ideal way to keep things calm inside your PC as liquid transfers heat more efficiently than the other cooling options. Liquid/Water cooling also makes your computer quieter as there will be no cooling fans.

Which one is better, tempered glass or without Glass?

There is no simple answer, and only you can decide which material is the best for your chassis. This is because both tempered glass or without glass panels have their pros and cons. In our opinion, tempered glass is the winner in this standoff. Even though tempered glass is much heavier but it is more sophisticated and allows for simple monitoring of inner PC’s components.
