ASUS announced ASUS Mini PC PN62, an ultra-compact computer that delivers powerful performance for a wide variety of home and business applications. Featuring the latest 10th Generation Intel Core processors and support for high-speed 2666 MHz DDR4 memory, Mini PC PN62 is ready to take on demanding workloads, yet its diminutive size takes up minimal space on a desk and makes it suited for applications where traditional PCs won't fit, such as digital-signage applications or in a home theater.

WiFi 6 (802.11ax) networking ensures stable, high-speed data transfers, even in crowded networking environments, and a USB-C port with Power Delivery (PD) supports data transfer, power and DisplayPort functionality over a single cable. Mini PC PN62 also features an infrared (IR) sensor and supports Microsoft Cortana via dual-array front microphones for convenient voice control of applications.
 
ASUS Mini PC PN62 has an energy-efficient design that reduces environmental impact while helping to lower operating costs in business environments or the home. The eco-friendly ASUS Mini PC series has received of some of the industry's highest environmental certifications, including Energy Star. Mini PC PN62 consumes as little as 8.14 W at idle. It is also whisper-quiet, generating just 21.5 dBA at idle and 36.9 dBA at full load.
 
So this mini PC should be very quiet and it's small form factor makes it adaptable to many situations in my opinion.
