Firstly thank you for the replys.
The sensors command detected only temperature measuring devices. It did not detect any fan controlling device. Your computer almost certainly does not have one. What is the make and model of the computer?
"fancontrol" is not a device but an executable in / for linux. I do have it, but terminal replied that it could not read the config file. That is one detail i will be looking to. Why is it not readable?
The laptop / notebook, is an old HP Pavilion model zv6000. Last production year all points back to 2004-2005.
There may be BIOS settings on it. However, the solution should be thought out. How many fans do you have and of what size and orientation ? If you have just one small fan, replace it with a large one (less noise, more efficient).
I had not looked at the BIOS, trusting some of what i had read saying there was no help in the bios. I will look into it.
There are two fans. I took apart the machine and cleaned it. Both fans inlet and outlet vents were clogged with dust and hair. The fan that has been making the noise was the only one i wrote down all the details on. This fan (the cpu fan) is 5volts DC, 3watts. The other fan apears to be an assistant. It engages upon boot up and heavy task load.
Since the cleaning the noisy fan is not as loud. I can say the propeller spindle does not have continuous rotation. That is when spun by hand there is a drag in the action. I would deduce from all things considered, the fan has been over worked / over heated.
Im way ahead of you on replacing the fan
. Still curious as to how to manipulate the fans with linux.
