So I dumped windows and installed Kubuntu 9.10. I'm having a loud problem though and after searching the forums I decided that I need to post my issue. The problem I'm having is that the fan(s) are spinning to fast and never slow down. Under windows, they would spin like this when the box was turned on, but after the OS was loaded they would simmer down and things were a lot less noisy. The noise from the fan(s) at full blast makes Kubuntu 9.10 unusable. The most useful previous forum I found was here: http://ubuntuforums.org/archive/index.php/t-238566.html and it gave a solution if the sensor on the motherboard was a it87, but that is not the sensor I have.
I have a Sony Vaio PCV-RX527 with a P4 1.7GHz, 512RAM and a w83627hf sensor on the motherboard. I installed lm_sensors and running the sensors command gives me the following output:
Running pwmconfig as the previous solution stated produces the following and I believe the root of my issue. PWM finds 2 controls, but says that their are no usable PWM outputs.
I played with /etc/sensors.conf only to realize that /etc/sensors3.conf was the file I should be changing. After I modified the sensors3.conf file I ran sudo sensors -s. While this does change the output of the sensors command the next time I ran it, it never changed the fan speed. I have since reverted the /etc/sensors3.conf and /etc/sensors.conf back to their original state.
Other notes:
Any help would be appreciated... noise is killing me

$ pwmconfig
This program will search your sensors for pulse width modulation (pwm)
controls, and test each one to see if it controls a fan on
your motherboard. Note that many motherboards do not have pwm
circuitry installed, even if your sensor chip supports pwm.
We will attempt to briefly stop each fan using the pwm controls.
The program will attempt to restore each fan to full speed
after testing. However, it is ** very important ** that you
physically verify that the fans have been to full speed
after the program has completed.
Found the following devices:
hwmon0/device is w83627hf
Found the following PWM controls:
hwmon0/device/pwm1
hwmon0/device/pwm2
There are no usable PWM outputs.

Other notes:
- I did install all the latest patches after installing Kubuntu
- fancontrol is not running and will not run. I believe this is because the fancontrol script checks the output of pwmconfig
- no errors found in dmesg that I can tell
- output from top that shows the box is not doing much
