I installed Ubuntu 9.04 on my AA1 (a0a 150) via a Wubi installation. The fan will not stop running even though the laptop is cool to the touch. I tried this fix: Some Acer Aspire One netbooks out there suffer from a noisy fan. Mine too and it was really starting to drive me crazy. I really wouldn’t want to be caught using it in a quiet place like a library for example. Luckily there’s a couple of scripts you can use to control the fan. The aspireone.net Wiki has all the details, but here’s a quick rundown of what you need to do to get rid of the noise: download the acerfand daemon script download the acer_ec.pl script (direct download) Copy both files to /usr/local/bin make acerfand executable using chmod 755 /usr/local/bin/acerfand open /etc/rc.local as root (or use sudo) and add /usr/local/bin/acerfand at the end of the file This did not change a thing. Does the Wubi installation prevent Ubuntu from controlling the fan?
