Hey Ramnarayan, Do you have a graphics card on your laptop? I had one where the graphics card drivers were not installed, and hence that made the system turn hot - which in turn runs the fan at very high speed. Check if your Ubuntu have proper drivers for the graphics card installed. If not, turn the graphics card off.
I have faced the problem in Ubuntu as well as Fedora.
