The natural Airflow cooling of Airtop is totally silent.
High power electronics system usually has some acoustic side effect commonly known as “coil whine” caused by mechanical vibrations in coils and capacitors amplified by the PCB.
In the design of Airtop motherboard special attention was given to make it inaudible.
The power supply is also silent.
The overall noise level of Airtop depends on the devices installed in it. SSDs, hard disks and graphics cards are not always silent. Airtop housing muffles sounds inside but since sound level varies with configuration and work profile and users vary in their sensitivity we cannot guarantee that everybody will find Airtop in every scenario silent.
We can guarantee that Airtop is orders of magnitude more quiet than any active cooling computer.
