How much does heat affect general perfomance?

Discussion in 'Laptops' started by adam.waterfield, Jun 26, 2006.

  1. I have a question re heat and general laptop performance.

    I have a Dell Inspiron which I bought in the UK, which I have now
    brought to Italy with me when I moved.

    It has been running fine up until about a month ago. Everything that is
    slightly demanding - a couple of games for instance, now run like a
    slideshow - these were liquid smooth before. The system in general is
    quite laggy.

    I have been tearing my hair out trying to find the issue. By trade I am
    a IT technician, and are 100% sure its virus and spyware free. The
    software seems perfect, everything is up to date, and whatsmore, I have
    made no changes that would reflect such a performance drop.

    However, the air temperature has increased by maybe 10C recently, at
    about the same time as my performance problems started.

    How much of a problem can this cause teh CPU? My laptop gets very warm
    in normal conditions anyway, but with the room temperatures probably
    been around 30-35c, how much could this affect it?

    My cpu seems to run at 100% a lot now, and it never used too.

    My problem has to be hardware, and the only thing I can think of is the
    heat increase. I thought some of my RAM modules may be screwed, but
    they appear to be ok.

    Any ideas?

    TIA, Adam

    Try blowing out the cooling vents with canned air...

    A pal of mine's Dell was running sluggish - after blowing two years of fluff
    out the vents it was back to normal.
    Many laptop CPU's reduce their clockspeed when they start to overheat.

  3. Thanks I will try that, although I assume it should be fairly dust

    The cpu clockspeed reducing when they start to overheat would make a
    lot of sense, do you know anyway to show if this is indeed happening?

    try Notebook Hardware Control... it's a tool for undervolting CPUs (and
    throttling) and it will show you your clockspeed every second, etc.

    Mobilemeter provides a realtime graph of CPU speed and temperature.

    Go inside where there is air conditioning and see if your performance
    goes back to normal.

  7. Thanks for all your suggestions, I will try these out.

  8. I installed one of those applications and it tells me that my CPU is
    running at 68c at idel / low load, and that my HD is at 50c.

    I understand the P4 does run hot, and that 60c would be considered
    normal during normal conditions, however, 50c seems hot for a HD.

    Would you agree that a HD at 50c would explain my system slow down?

    nah, most hard drives have no problems at 50c.

    what did you install a month ago?

    i would say coincidence.

    this points to a software/driver problem. whatever you installed a
    month ago is the culprit. it might not like interacting with other
    software, etc. what process is running at 100%?

    Depends on the hard drive. Some are specified with a maximum running temp
    of 45C, some with a max temp of 55C. The firmware in many drives records
    the max temperature they are operated at.
    The cooling air flow route blocks up quite quickly, and a P4 is particularly
    vulnerable. Apply a vacuum cleaner nozzle to the air intake on the
    underside of the machine periodically to remove the dust and fluff.

    Try this
    Open a command prompt
    Type: chkdsk c: /f and press ente
    You SHOULD get an error message saying something about you need t
    reboot. Press the Y ke
    CHKDSK will run and fix any problems it find
    After the reboot do a defrag of the hard drive

    A fragmented hard drive can cause all kinds of frustrations

    IF the above doesn't work, I would download a cleaner such as Syste
    Mechanic from www.iolo.com or ccleaner (do a google search for it,
    don't have their web site addy handy)

    Install one of the above, run it, then do another defrag
    You should perform the above on a regular schedule to keep your p
    free of junk and in top performance, depending on whaty you do

    For complete accuracy, chkdsk only checks the structure of the HD:NTFS,
    security system, etc. It does not defrag, for which one uses
    defragmenter. Chkdsk /f "fixes" the NTFS, chkdsk /r "repairs" which
    fixes the NTFS and checks and mapps out bad sectors.
