Build SFF Silent PC for HTPC, 1080p Gaming and Work

If you are thinking of building a small form factor (SFF) quiet and silent PC for gaming, HTPC, video editing, etc. then you are at the perfectly right place. Some users do not like the noise from the PC as it can affect their work and productivity. Therefore they look to build a compact silent PC for their work or gaming needs. A quiet or silent PC generates very minimal or almost no noise that is barely audible by your ears.

The main components that are responsible for making noise in a PC are fans and hard drives. You can find fans on the CPU cooler, Graphics Card and in your PC Case for increasing airflow and reduce components temperature. Generally, graphics cards fans and PC case fans are responsible for most of the noise in a desktop computer but they are also very important for cooling, otherwise, it can lead to increase in the temperature of the computer case, graphics card and other components that can lead to some serious damage. But there are some graphics cards that come with a passive cooling solution without fans, and are quite powerful and can be used for casual gaming and for Home Theatre or HTPC purpose.

To reduce the noise of case fans, you can use high-quality silent case fans that generate very little noise which is barely audible when working on the PC. Some Mechanical hard drives can be very noisy and they can get pretty loud during gaming or when working continuously. Also to reduce the noise altogether you will need a good silent PC case that can absorb the noise from the components inside. So here in this post, I am going to list down the various components that you can get for building a powerful silent PC for casual gaming, HTPC and for other normal office & home use.
