Silent PC | Fanless Quiet Computer


What is A Silent PC?

A silent PC is essentially a computer that generates little to no noise at all. A silent computer eliminates moving components that create noise like a fan. Hence, most silent computers are fanless, they passively cool down the components using highly conductive heatsinks that are made from aluminum and copper. A quiet PC has many use cases that can be utilized for industrial applications as well. Thus, in this blog, you will be guided on how fanless silent computers are built for industrial applications.


Why Do You Need A Truly Quiet Computer?

You need a truly quiet computer for your industrial applications because it can reduce its noise production down to zero decibels. A silent PC won’t produce any noise pollution around the industrial environments which is very beneficial for industrial applications that require a silent or noiseless environment.


Within the industrial environment, there is a multitude of complex equipment that is required to be handled effectively and efficiently. With mission-critical industrial applications, users are expected to remain consistently productive for maximized throughput. With all the distractions of devices and heavy equipment around the industrial applications, it’s comprehensible that we need less noise in order to escalate worker’s productivity and safety around the industrial environments. Moreover, some industries required a truly quiet environment and a silent PC to deliver optimal environments and services for their stakeholders.


One of the main reasons why silence is an important factor in industrial application is it helps workers to concentrate. Running multiple tasks for hours is not an easy job. With many devices and machines, noises enter your brain all at once might take away a worker’s ability to focus and being productive. When the sound reaches around 80 decibels, it’s very likely to distract the workers during work. Besides, silence can increase worker’s awareness and safety. When there are many moving heavy or dangerous equipment around the working environment, silence can improve worker awareness of its surrounding which also lead to a safer environment. Moreover, silence will also provide a sense of calm and reduce stress on workers, offering them a chance to rest and relax in the industrial environment.


Where do You Use A Silent PC?

Silent Fanless PC is absolutely critical in some industrial applications to ensure smooth operations and success amid deployments. Truly quiet fanless PC is very useful in various environments such as hospitals, lab facilities, kiosk & retail, in-vehicle solutions, and transportation systems. Ordinary industrial and commercial computers generate loud noises that disrupt comfort, thought processes, communication, awareness, and much more. 

The Healthcare industry is one of the good examples of why you need to install a silent fanless PC instead of an ordinary PC that produces noises. Noises in the hospital may disturb the patients and even increases stress that will lower down the immune function, reduced pain tolerance, and impaired wound healing. Thus, applying fully silent computers around the hospital will significantly improve patient satisfaction and the hospital’s productivity.




4 Aspects That Build A Fully Silent Computer?

A quick rule-of-thumb for ensuring you’re getting the best silent fanless computer is to check the computer’s architecture that has the least amount of moving parts. The fewer moving parts a computer has been mostly positively correlated to the less noise a PC will generate. With fewer moving parts there is also less point of failure that can significantly reduce downtime risk. Thus, a great fully quiet PC will eliminate as many moving parts as possible which not only removes noises but also dramatically increase the computer’s durability and reliability.

1. Fanless Design

A fan is one of the biggest noise sources from a computer. A fan is pretty effective to cool down the computer’s component especially the CPU (central processing unit) which is the PC component that generates the most heat. It is essential to have a cooling solution for your CPU to avoid throttling when running a high-performance application.


Despite the effectiveness of cooling down the CPU, a fan is not an optimal cooling solution for industrial applications, especially when it requires a truly silent computer. Hence, a silent PC utilizes passive cooling for a fanless design that can effectively cool down the computer's component without using any fan or moving parts that might produce noises. Instead, the fanless design utilizes highly conductive heatsinks made out of aluminum and copper. These heatsinks then are attached to the computer’s CPU and PCH (platform controller hub) which then transfer the heat to the computer’s enclosure to dissipate away from the heat. Copper heat pipes are also used on the computer’s enclosure to efficiently transfer and dissipate heat naturally on the silent PC’s surroundings.


2. Storage Drive – SSD


Hard disk (HDD) is another major source of noise among the computer’s components. HDD reads and writes its data by using an actuator arm to manipulate the data on a spinning metal disk that spins extremely fast with a spin rate as low as 1,200 RPM and can reach up to 15,000 RPM. This is why HDD not only produces so much noise, but it also is very prone to fail around industrial applications that are known for their extreme environments. That said, SSD or solid-state drive is a perfect solution for industrial and silent fanless PC. SSD relies on semiconductor chips or so-called NAND chips that are capable of retaining their charge without a power source that is manipulated to read and write data. The flash memory on SSD makes it smaller, faster, more durable, lighter, and a superior quiet solution to use compared to HDD storage drives.

3. Cable-less Design


Silent fanless PC is also applying cable-less design where all the chips and components are soldered right onto the motherboard. The internal design is cable-less which can increase the computer’s durability and reliability against tough shocks and vibrations. Additionally, it also prevents cable routing & cable matching problems and prevents cabling signal degradation and latency. That said, cable-less design not only makes the silent fanless PC truly quiet but is more reliable amid industrial deployments in extreme environments.


4. One-Piece Design


To make things even further, truly silent fanless computers have a one-piece design for their enclosure. Compared to other industrial and commercial computers case that have many joint parts and vibration points that can be the source of noise, a silent fanless computer has a one-piece design enclosure. The enclosure is made out of a single mold extruded heavy-duty metal that creates a robust structure and provides extra protection. With fewer joint parts, gaps, and screws, the sealed housing can prevent dust ingress, increases durability, and more importantly, it is fully quiet.
