Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I recently bought a new laptop and I'm now trying it out as a linux host for virtual development machines (mostly one at a time) in virtualbox.
this is my first try with linux as a desktop @ work, so far everything is working (almost) out of the box but I'm a bit concerned with fan speed management.
I installed several system monitors and they agree in reporting these temperatures (idle host and idle VM, cpu load about 20%):
cpu - mobo (2 sensors) -> ~33°C
what I understand should be the gpu -> ~45°C
and that's ok with me.
my worries start when cpu load raises:
sensors report constantly increasing temperatures going in the 45°C (cpu) - 60°C (gpu) range, with +7°C spikes
and that's with just 60% cpu load peaks, 30-40% bottoms for a few seconds (30-60 tops)
I can see something is happening with fan speeds, since before installing NVIDIA drivers gpu temperature got in the 80°C range in a few minutes while idle (that's dangerous btw..) but still, fan noise doesn't change noticeably, while at pc boot I can clearly hear the fan can spin much faster.
luckily I'm working on low load procedures at the time, but I don't know how much this will last..
I'd like the fan control to be more "aggressive" but I didn't manage to find any setting around (followed a couple guides)
For example I tried with lmsensors and ksensors but they seem to fail detecting any fan controller device and BIOS has just a "fan always on" option (which is enabled).
