Quiet Computing with BSD

Programming system hardware monitors for quiet computing

In this talk, we will present a detailed overview of the features and common problems of microprocessor system hardware monitors as they relate to the topic of silent computing. In a nutshell, the topic of programmable fan control will be explored.

Silent computing is an important subject as its practice reduces the amount of unnecessary stress and improves the motivation of the workforce, at home and in the office.

Attendees will gain knowledge on how to effectively programme the chips to minimise fan noise and avoid system failure or shutdown during temperature fluctuations, as well as some basic principles regarding quiet computing.

Shortly before the talk, a patch for programming the most popular chips (like those from Winbond) will be released for the OpenBSD operating system, although the talk itself will be more specific to the microprocessor system hardware monitors themselves, as opposed to the interfacing with thereof in modern operating systems like OpenBSD, NetBSD, DragonFly BSD and FreeBSD.
