Fan Speed Control - Please Help !


Hey Guys

What I did on my windows 7 was :

Run TurboV and underclock my cpu speed from 4x 3.2 to 4x 2.4 GHZ .
Run Speedfan and set cpu and chassis fan to 20%

And I was good to go ! Now I am a newb and I don't want to touch cpu clocks but I really need to tune down fans before it drive me nuts !

I Came across 3 Names : pwmconfig , im-sensors , thinkpad fan , But since I am new I can't understand any of the online guides . So if anyone could explain in simple or post a link so I can cut about 300 RPM I would appreciate .

TNX in advance

System : Ubuntu 10.4 LTS
CPU : Phenom II X4 955
Motherboard : ASUS M4A79T DELUXE
Cooling : Cooler Master V8

A cooler master V8 on an ASUS motherboard shouldn't be noisy, even if you don't underclock. At first I would check if the fan control in your BIOS is activated, normally this alone should do that job.

In short: When the machine starts press repeatedly the "Del"-key at the BIOS prompt so that you enter the BIOS screen. Use the cursor keys to change to the "Power" tab. Activate the options "CPU Q-Fan function" and "Chassis Q-Fan function". A few new options will appear, change "Quiet CPU Fan Mode" and "Quiet Chassis Fan Mode" to "Silent". Now save the settings with pressing the F10 key and Enter, the system will reboot and should be much quieter.
If the options are already activated or the system is not quieter afterwards check the CPU temperatures. It may be that your CPU cooler is not mounted correctly if they are to high.

I almost always handle this with the BIOS's built in fan speed control, like Tobi described

Yes I know that V8 is much much quieter compared to stock ones but still when you keep your case's left door open and the case in about 30 cm from where your keyboard is there is still a noticeable noise . and I also have a chassis fan that is pretty loud . So I really want to lower their speed and keep them low .

And yes I know about the BIOS but still the chassis speed is high and I want to tune down and keep it down . speedfan did that job well for 3 years now I want to find a Linux alternative

And my temps are fine I only want to do this because of the noise .

I did try to install thinkpad fan . I installed it from software center but I didn't find any shortcuts or any ways to run it in terminal . I managed to read the read-me and it says " ou are required to have the Linux kernel with 'thinkpad-acpi' patch.You must also enable manual control for your fans. For Linux 2.6.22 and above." which I have no Idea what it means .

I tried this guide for im-sensors : http://ubuntuforums.org/showthread.php?t=42737
which says go here : http://ubuntuforums.org/showthread.php?t=2780

I followed until the line that says :
{

b. Make the file executable:
chmod 755 mkdev.sh
c. Run mkdev.sh from the current directory
sudo ./mkdev.sh

}
I don't know how to make it executable .

So can you guys help me setup one of these 2 ?

Why are you doing that? That is effectively killing the airflow, rendering the chassis fan more or less useless.

thinkpad-fan, as the name says, is for laptops from Lenovo/IBM, not for desktop machines. You should use fancontrol instead, together with lm-sensors.

They gave you the command to make it executable, it is
Code:
chmod 755 mkdev.sh
My opinion: Instead of fiddling with software and underclocking a fast CPU I would invest some money to replace both fans with silent versions.
