Please note that this software is specific for Linux as it depends on certain unique features of the Linux kernel.

NEW: vaiofand can now handle overheating systems as well and make the fan spin faster to ensure proper cooling.

Simple installation, including init scripts for major Linux distributions.

Debugging mode with logging into syslog to facilitate users' tuning.

If temperature approaches critical levels to prevent system damage

Temperature being monitored at all times, and fan automatically set to full speed.

Fully configurable through /etc/nf (temperature thresholds, desired fan speed, frequency of checks …).

Speed when the temperature reaches user-defined thresholds.

Vaiofand can also make further adjustments to the fan The fan speed at user-defined rate by constantly overruling the settings Vaiofand monitors the system temperature and maintains Spinning at considerably higher rates than necessary and so generateĮxcessive noise. These fans are controlled directly by the BIOS and thus do notĪllow for standard software management. Vaiofand is a Linux system daemon to tame the noisy fans of Sony Vaio
