Thanks to the below link, I was able to turn down the annoying fans on my old Sony PCV-RX650 while running Ubuntu:

\nThis problem has been bugging me and preventing me from running Linux on this system. I’m glad I was able to resolve this problem without having to upgrade the BIOS (~ $30) to have the latest ACPI 2.0 feature (currently it has APM).<\/p>\n
I first found out that I need to activate the root password on Ubuntu by running “sudo password root”, this allows me to act like root.<\/p>\n
I then followed the instructions of getting and installing the lm_sensors package first by running “sudo apt-get install lm-sensors”
\nrun: sensors-detect (answered “yes” to all of their questions)
\nThis basically add the following lines to \/etc\/modules:
\n#====================================
\n# Generated by sensors-detect on Thu Aug 23 23:44:40 2007
\n# I2C adapter drivers
\ni2c-i801
\n# Chip drivers
\neeprom
\nw83627hf
\n#====================================
\nreboot to have the modules loaded<\/p>\n
run: pwmconfig
\nto set the preferences
\nyou can try to run fancontrol at this point as root to see if it is working.<\/p>\n
Finally add a line below to to \/etc\/rc.local (to allow for auto execution upon power up)
\n\/usr\/sbin\/fancontrol &<\/p>\n
Below is the transcript of what I did:

dtsai@ubuntu:~$ pwmconfig
\nThis program will search your sensors for pulse width modulation (pwm)
\ncontrols, and test each one to see if it controls a fan on
\nyour motherboard. Note that many motherboards do not have pwm
\ncircuitry installed, even if your sensor chip supports pwm.<\/p>\n
We will attempt to briefly stop each fan using the pwm controls.
\nThe program will attempt to restore each fan to full speed
\nafter testing. However, it is ** very important ** that you
\nphysically verify that the fans have been to full speed
\nafter the program has completed.<\/p>\n
Found the following PWM controls:
\n 9191-0290\/pwm1
\n 9191-0290\/pwm2
\n 9191-0290\/pwm3<\/p>\n
Found the following fan sensors:
\n 9191-0290\/fan1_input current speed: 4530 RPM
\n 9191-0290\/fan2_input current speed: 2280 RPM
\n 9191-0290\/fan3_input current speed: 0 … skipping!<\/p>\n
As you are not root, we cannot write the PWM settings.
