Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

I've been having overheating issues with Ubuntu 13.04 (and probably before as well, but I wasn't doing anything as intensive as I am now) and I'm noticing that the fan never kicks into "jet engine" mode like it used to with Windows 7.

Honestly I don't mind the noise, I just want to be able to push through the tasks I'm working on WITHOUT SERIOUSLY DEGRADING MY PERFORMANCE. I've already looked into setting my power consumption lower and things like that. Does Ubuntu not have full control over the fan? Knowledge/instruction is welcome in addition to advice.
