temperature

So I have a machine which has both latest *Ubuntu and Windows 8 on it. On windows 8 my CPU temp is roughtly 26 degrees when idle. Now when I boot into Ubuntu, CPU temperature is suddenly 43 degrees when idle, plus my fans are making a lot of noise which is probably because of the CPU degrees.

Why is that? Everywhere I read it says the Linux is much better at managing CPU and so on. But yet it seems something is wrong.

It is a stock installation of Ubuntu 14.04 and my CPU is a Intel i5-4570

disparity between `top`'s given CPU % and process CPU usage total

I've noticed that there are sometimes (large) differences between the reported total CPU usage and a summation of the per-process CPU utilization given by apps like top and wmtop. As an example: I recently ran a git filter-branch --index-filter on a fairly large repo, with the index-filter command… >>> More
