acers3fand

acers3fand is a script which controls your Acer Aspire S3 Ultrabook fan speed by cpu temperature. It is designed to work with Intel Core i5 CPU but might work with other cpus as well.

IT IS POSSIBLE THAT YOUR LAPTOP WARRANTY WILL BE VOID AFTER USING THIS SCRIPT! BE ALWAYS OBSERVANT AND ACT IF YOUR LAPTOP BEGINS TO BE TOO HOT OR THE FAN IS NOT SPINNING!

"sudo killall acers3fand" will restore your fan to state AUTO but will not remove the auto-start script so it is running again after bootup

For Ubuntu (Gnome) users we would also recommend using Jupiter indicator application (in addition with acers3fand) to manage cpu frequency and power stages to get lower temperatures and allow acers3fand to make your laptop even more quiet!

Kernel versions 3.x and above (Ubuntu 11.10 and newer) are also recommended.
