Chapter 3. Noise Reduction
Most of the noise emitted by a computer is produced by the fan, the harddisk and the speakers.
libsensors0 is a library to read temperature/voltage/fan sensors
"Kernel drivers to read
temperature/voltage/fan sensors. This is a module for reading the
temperature/voltage/fan sensors in Linux via the LM78/79 chip and
possibly sensors on the SMBus (System Management Bus, usually found in
P6 and P-II systems). The LM80 and a LM78-clone called W83781D are
ACPI, see APM chapter
can be configured by the user as an expert controller: The user can
specify the max/min speed of the system fans, the maximum affordable
temperature and so on. The controller tries to reduce fan speed to reduce
noise while the temperature is in a safe range chosen by the user. So fan
speed is modified automatically by the control algorithm, you don't have to use
those mechanic or thermal regulators on your fans anymore.
