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'd like to control the fanspeed on all the following:
GPU HD2600 Pro AGP
Antec True Power 330 ATX
My motherboard is the Asrock 775i65G v2.03.
Should I start a new thread or keep this one alive?
Board has two fan connectors. If you have other fans that you want to control then a fan/speed controller can be used. You can get cheap potentiometer type controllers but if you wish finer control then look at 'PWM' type controllers that will cost you a bit more.
If you scroll down to find 'similar threads' to open other threads for information.
I appreciate the welcome and thanks for the attention. Yes, the board only has two 4 pin fan headers (one for the power supply and one for the CPU) but I was under the impression that the GPU fans were also controllable via PWM control software, was I mistaken?
Most new GPU do have 'PWM' ability. But the board you stated supports;
excerpt from http://www.xpcgear.com/asrock775i65g.html
- CPU Temperature Sensing
- Chassis Temperature Sensing
- CPU Overheat Shutdown to Protect CPU Life
- CPU Fan Tachometer
- Chassis Fan Tachometer
- CPU Quiet Fan
- Voltage Monitoring: +12V, +5V, +3.3V, Vcore
You should be able to control a GPU fan via the 'chassis fan point'. It will depend on the start and end points for fan controller. If the BIOS allows you set a range that fits the 'GPU' then it should not be a problem. 'fan' labeling will not show as 'GPU' unless you can change the label. Some external controller programs allow re-label.
I would use the MB fan ports as intended then add a separate controller for 'GPU'. You can find inline fan speed controllers that are 'PWM'.
As I said the driver version will dictate. Most external graphic cards do control the GPU HSF to maintain temp via fan speed. You could provide external fan speed control as I stated earlier but if you do not close the loop by temperature monitor then damage can be likely.
Noted. I won't add any hardware to achieve fan speed control so that's out. I would rather not use the ATI/AMD proprietary driver so the question becomes will the utility from that package work with the open source driver or is there another functionally equivalent tool to it.
Update: I noted that libsensors4 is installed, how do I use it to check on the sensors and report?
