I have a laptop,
Model: Compaq Presario CQ40, RAM: 2.7 GB RAM, Processor: AMD Athlon X2 Dual Core QL - 64*2, Ubuntu 12.04.3 LTS 64 bit and Windows Vista 32 bit (Factory Installed)
My laptop gets heated up a lot when I am using Ubuntu and the fan runs continuously (I have not chosen "Continuously On" mode for the fan in BIOS settings) . I am using Jupiter with Power Saving mode as of now, and the heat has reduced a bit. Also I am using Ubuntu2D instead of the default option while logging in.
The temperature is 65+ degrees C when I am not doing much on my machine and gradually increases to 75+ when doing several things at once. I intend to use CDH Hadoop in Pseudo Distributed mode on my machine. I can guess what the temperature will shoot up to then because it uses JVMs. What are the possible things I can do to reduce heat and the fan noise?
