I recently installed ubuntu 13.10 on my Asus laptop with windows 8.1 on it. After installation I am finding that the fan, for some reason is continuously on. I checked the RAM and processes list to see if it is running a lot of them but everything seems to be normal there. Hardly 1.2 GB(out of 4 GB) of RAM is being used. I also checked the sensor and all their temperatures seem normal. But I am not able to figure out what is causing the fan to be on always.
