    Thinkpad T430u fan stuck at 0 RPM

    I've been noticing lag spikes in my games after I've been playing for a while away from my cooling pad. after I noticed this I realised that the fan hasn't been running at all...

    So I installed a few things to look into this and see if I could correct the problem, here is the output of sensors:

    Code:
    gilligan@ThinkPad-T430u:~$ sensors
    acpitz-virtual-0
    Adapter: Virtual device
    temp1:        +75.0C  (crit = +130.0C)
    
    
    coretemp-isa-0000
    Adapter: ISA adapter
    Physical id 0:  +68.0C  (high = +87.0C, crit = +105.0C)
    Core 0:         +67.0C  (high = +87.0C, crit = +105.0C)
    Core 1:         +67.0C  (high = +87.0C, crit = +105.0C)
    
    
    thinkpad-isa-0000
    Adapter: ISA adapter
    fan1:           0 RPM
    temp1:         +0.0C  
    temp2:         +0.0C  
    temp3:        +75.0C  
    temp4:         +0.0C  
    temp5:         +0.0C  
    temp6:         +0.0C  
    temp7:        +39.0C  
    temp8:         +0.0C
    I can tell you now with the metal base on this laptop it get pretty toasty having this thing on your lap
    anyway

    Next I tried to configure the fan speeds manually with pwmconfig:

    Code:
    gilligan@ThinkPad-T430u:~$ sudo pwmconfig
    # pwmconfig revision 5857 (2010-08-22)
    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 is acpitz
       hwmon1/device is coretemp
       hwmon2/device is thinkpad
    
    
    Found the following PWM controls:
       hwmon2/device/pwm1
    hwmon2/device/pwm1 is currently setup for automatic speed control.
    In general, automatic mode is preferred over manual mode, as
    it is more efficient and it reacts faster. Are you sure that
    you want to setup this output for manual control? (n) y
    hwmon2/device/pwm1_enable stuck to 2
    Manual control mode not supported, skipping hwmon2/device/pwm1.
    There are no usable PWM outputs.
    Soooo....

    What now? I'm completely stumped as to what to do now.
    any help would be much appreciated

    Regards

    Daniel

    I found this: http://askubuntu.com/questions/11401...rol-via-procfs

    is there any way to make this more dynamic? setting it to auto leaves it at 0 RPM

    Re: Thinkpad T430u fan stuck at 0 RPM

    I found this: http://staff.science.uva.nl/~kholshei/thinkfan_guide/

    currently trying it out, I would like to know more about how to choose starting and ending temps for each fan speed

    can I just use anything in here:

    Code:
    (0, 0, 51)
    (1, 50, 52)
    (2, 51, 55)
    (3, 54, 58)
    (4, 56, 63)
    (5, 60, 70)
    (6, 66, 79)
    (7, 74, 92)
    (127, 85, 32767)
