Why my Laptop is getting hot, with a normal CPU usage?

    Dear guys,
    I have problem with my fan speed, seems it is working at max n quite non-stop.
    I have google around to have a software that can monitor fan speed or CPU temperature. there are some option, but all of them failed to be used(for me,:().
    Code:
    mbmon

    Error Output:
    Code:
    No Hardware Monitor found!!
    InitMBInfo: Unknown error: 0


    Code:
    healtd

    Output:

        3:    0 rpm            - 5.0V:   -6.654V
    

    But seems this software doesnt give me idea, why fan run so fast,?
    I have monitored my CPU usage, and it is just okay(normal usage,0-10% usage).
    Any idea on this?,
    I am just installed Gnome, seems this problem occur after that, any relation with that?
    here following some detail of my freebsd configuration.
    Code:
    $ cat /etc/rc.conf

    What mainboard do you have (chipsets)?

    Try kldloading smbus(4) and iicbus(4).

    Then try to run mbmon with the -A switch.

    And it produces error,

    This program needs "setuid root"!!
    I have with root privileged,
    and i have change the file permission of mbmon,
    Code:
    sudo chmod +s `which mbmon`
    ,*suggestion found in Google.
    ,
    Now i just relied on a simple command,
    Code:
    sysctl -a hw.acpi.thermal.tz0.temperature 

    What do u think the realiable of the output, by using this command? I got 74-75 C, with this cpu usage
    CPU: 1.1% user, 0.0% nice, 6.4% system, 0.2% interrupt, 92.3% idle.
    Any idea how to investigate why my laptop are getting too hot(for me 75 C is too hot, just a normal usage).

    Thanks for the responds.

    As it seems you have and AMD, try kldload k8temp (amdtemp on STABLE/CURRENT).

    Yes, I am using AMD Turion 64x2,
    I have added the module 'k8temp', seems it has same error.

    How good accuration of this command(below) ?
    Code:
    sysctl -a hw.acpi.thermal.tz0.temperature


    Again Does it normal to have temperature 73-75 C ?
    Thanks.

    It does look somewhat high..

    Code:
    root@molly:~#sysctl -a hw.acpi.thermal.tz0.temperature
    hw.acpi.thermal.tz0.temperature: 40.0C

    Read some of the suggestions here and see if they help.

    In particular, I highly recommend that you try this in /etc/rc.conf:
    Code:
    powerd_enable="YES"
    powerd_flags="-a adaptive -b adaptive"


    I seem to remember reading (a few years ago, mind you) AMD releasing a statement that temperatures at or above 64C were known to cause damage to their processors. Hopefully they have toughened this threshold since laptops tend to heat up _alot_, but I think 73-75 (if accurate) is far too high.

    Edit: I would also suggest a notebook cooler. Zalman makes a very good one for pretty cheap.

    A somewhat common problem is that the heat outlet for the CPU fan gets blocked by dust, this is something you might want to check out.

    I'm not familiar with BenQ notebooks, so I can't offer you any specific advice, but usually you can reach the fan pretty easy by either removing a plate on the underside or by removing the keyboard ... But for some notebooks this can be a bit more difficult.

    I think i have read that thread, i am using different flags for powerd(first suggestion in the thread),
    Code:
    > cat /etc/rc.conf
    
    # -- sysinstall generated deltas -- # Sat Jun  6 00:56:55 2009
    # Created: Sat Jun  6 00:56:55 2009
    # Enable network daemons for user convenience.
    # Please make all changes to this file, not to /etc/defaults/rc.conf.
    # This file now contains just the overrides from /etc/defaults/rc.conf.
    
    # PC information
    keymap="us.iso"
    
    # Run daemon
    inetd_enable="YES"
    
    # Network Environment
    ifconfig_re0=DHCP
    nfs_client_enable="YES"
    sshd_enable="YES"
    hostname="ykt.void"
    
    # GNOME environment(gdm,had)
    gnome_enable="YES"
    
    # Hardware efficient
    powerd_enable="YES"
    powerd_flags="-i 85 -r 60 -p 100"
    
    # Others
    linux_enable=YES
    

    Will try other option later,

    Yes, it could be the problem, i nvr check my fan since i bought almost 3 years ago,
    Btw, does it sound possible to vacuum the fan, using a vacuum cleaner? do you think it is just fine for the laptop.

    Thank for the respond.
    yes, i will rebuild my kernel and set to the max frequency,but now now, later on.:)

    When i checked my sysctl config in detail, i have some question regarding my current setting. i found that:
    - I just only have one CPU state:
    Code:
     sysctl -a | grep cx_supported
    dev.cpu.0.cx_supported: C1/0
    dev.cpu.1.cx_supported: C1/0

    - Only shows one CPU frequency, (I am using dual core), it should have other info for other core(correct me if am wrong):
    Code:
     sysctl -a dev.cpu | grep .freq
    dev.cpu.0.freq: 1600
    dev.cpu.0.freq_levels: 1600/100000 1400/87500 1200/75000 
    1000/62500 800/27690 700/24228 600/20767


    Is something wrong with that?

    Thanks.
    Here some-info about my 'sysctl -a | grep cpu'

    So set C1 as deepest state the CPU can get into, C0 is running state, while C1 is first step to slow/cool down a CPU.

    You current CPU frequency is 1600 [dev.cpu.0.freq] while tou have 7 other freqs available to set [dev.cpu.0.freq_levels], currently on most CPUs (most dual cores for sure) you set freqency for both cores (not very optimal, but works).

    I have checked it, but I havent found any other things you can do with you CPU to save more power, but this thread may help you to lower overall power usage:

    I don't think a vacuum cleaner has enough power, but you can try I guess ...

    Do you think with my current configuration of power usage,
    it could lead to be high temp (70-75 C) ?, because now i am still blind why it can be that high?

    But i will try to do some stuff, like previous suggestion:
    - Clean up the fan (Just use vacuum:) or Disassembling laptop)
    - set max frequency of processor.

    will give update later.
    Thanks for the respond.

    If I am not mistaken, all of the info about ACPI is extracted from ram.
    If the Hardware is having issues or the ACPI kernel module is buggy there is not much you can do unless you can debug and help write patches.

    ACPI loads before the BIOS P.O.S.T.
    Only ACPI kernel module can reprogram ACPI controler.
    Only access to ACPI kernel module is via ACPI Driver.
    All is designed to be hidden (Specification word "transparent") from OS.
    ACPI designed by MS, Intel and Toshiba during a time when MS was actively trying to destroy the competition.

    ACPI Diagram of HW Interaction
    The red items are the ACPI HW components.
    ACPI controllers are made by Winbond, SMSC and others.

    Are you using the latest BIOS version for your Joybook?
