  1. [ubuntu] Re: Getting HP ProBook 4530s silent, maybe DSDT patching?

    My fancontrol script uses a parabola function to calculate the fanspeed.
    The formula is (temp-maxtemp)*(temp+maxtemp)*(-24/1000), here is what this looks like on wolframalpha:...

    Hello,

    after receiving several messages about my probook fan control script, I'd like to share my updated version with you.
    I've written this script as a service. It will start with your boot...

    The command to check the current cpu temp is correct.

    An output like:


    0:80:180:70
    0:80:180:75
    0:80:180:80
    0:80:180:85

    Could you please post the output of the following commands:


    sensors | grep Core
    sensors | grep Core | sed -e "s/ //g"
    sensors | grep Core | sed -e "s/ //g" | cut -f2 -d ":"
    sensors | grep...

    finally: :-)
    TMP=$(sensors | grep Core | sed -e "s/ //g" | cut -f2 -d ":" | cut -b2-3 | sort -n | tail -n 1)
  7. [ubuntu] Re: Help getting HP ProBook 4530s silent, maybe DSDT patching?

    using the following should solve your problem:

    TMP=$(sensors | grep Core | cut -b18-22 | sort -n | tail -n 1)



    #!/bin/bash
    LOGFILE=/var/log/fanspeed.log...
  8. [ubuntu] Re: Help getting HP ProBook 4530s silent, maybe DSDT patching?

    Change line 28 to
    TMP=$(sensors | grep Physical | cut -b 18-19)

    It should look like this:
    TMP=$(tail /sys/class/hwmon/hwmon1/device/temp1_input | cut -b1-2)

    3 posts in 15 hours? It's weekend. ;)
    Try setting 'Fan always on on AC' to Off in BIOS.
    the temps can be adjusted in fanslow.sh , look for value 55, this is the first step.

    hi vickoxy,

    i'm using ubuntu 12.04 on my probook 4530s for several month now. With my FanControl-Script, your system will be as silent as you hard drive is. It means: the fan will be off under...

    Hi pieceofcake,
    you're right.

    for those who receive a cpu temp value by running "tail /sys/class/hwmon/hwmon1/device/temp1_input | cut -b1-2", you can change line 28 of fanslow.sh:

    #from:

    my solution isn't that good, but i will share it:

    1. install:
    sensors
    perl (or be able to run .pl files)

    2. extract and modify:
    - fanslow.sh: on...
