Fan Control?


I have a couple of fans connected to my computer. Does anyone know how I can reduce the voltage across my fans to %50? If its of interest, the fans are plugged into an Asus A8V Deluxe motherboard which has a Via K8t800 Pro chipset.

For fan control, you will need to setup lmsensors first, then the fancontrol utility. I'm assuming that your distribution includes this software and it just needs to be configured. Otherwise, you will need to install the lm_sensors package (which includes the fancontrol utility).

To setup lmsensors, run:

sensors-detect

Follow the instructions, and make the necessary changes to /etc/rc.d/rc.local and /etc/modprobe.conf.

Once that's done, you can setup the fan control. There may be a bug in the pwmconfig fancontrol setup utility, that you may need to patch. Once you successfully run pwnconfig, you will have a /etc/fancontrol file, which will look something like this:

Code:
INTERVAL=5
FCTEMPS= 2-0290/pwm2=2-0290/temp2_input
FCFANS= 2-0290/pwm2=2-0290/fan2_input
MINTEMP= 2-0290/pwm2=25
MAXTEMP= 2-0290/pwm2=45
MINSTART= 2-0290/pwm2=120
MINSTOP= 2-0290/pwm2=85
You can then add the following to your /etc/rc.d/rc.local:

/usr/sbin/fancontrol &> /var/log/fancontrol.log &

I'm in FreeBSD 5.4 at the moment. There seems to be no "sensors-detect" command.

FreeBSD does not have a port of lmsensors so you will have to use an alternative. I found this http://listserver.uk.freebsd.org/pip...ay/003494.html
