I recently installed Ubuntu and now have a dual boot Windows and Ubuntu machine. The problem is that whenever I run Ubuntu, the computer heats up even when I'm doing the most meager of tasks.
For example, when it's idle it's usually at 64°C and once I open Firefox and only have a couple of tabs open it shoots up to over 80°C. My computer runs much cooler on Windows. I suspect some unnecessary use of resources.
The question, what's the best way to diagnose what's going on?
