cpu fan roaring up fast and furious

    I'm another one of those joyous persons who have a cpu fan hike, not in
    price, but just spinning up so fast, I fear this laptop is about to roar
    into orbit.
    This problem developed this past weekend for no apparent reason,
    although there obviously has to be one.
    I believe it to be software related, but for the life of me (or for the
    laptop of me) cannot narrow it down to what the culprit it.

    The cpu goes from 1% up to 50% then down again to 1-2% and up and down
    it goes!!!

    I'm using a Toshiba laptop P200 with Vista Home Premium Service Pak 1.


    Is there such a thing as a well known fix for this type of thing ...
    I'll appreciate your help with this.

    Guys, it's ok ... take your time and type out what you have to say very
    slowly so we on this end can understand what you are trying to convey.
    Up to this point, it appears you've not a whole lot up your sleeve, but
    don't be embarrased --- it's ok.

    If someone new happens to light upon this skill testing question,
    please advise. Thanks!

  4. I'm not sure I completely understand your problem.. you are saying that
    the fan randomly moves from a slow setting to a fast one? Is the fan
    making excessive noise, or is it just a problem with the speed at which
    the fan is spinning? Are you seeing spikes in processor usage, and the
    fan is following the spikes?

    Sorry that you didn't get that posting(s) Brian --- in your words, the
    fan is following the spikes. As stated in my first posting, the cpu is
    roaring from 1% usage to 40 - 60% usage. For the life of me, I can
    understand what is doing this, for I can't think of any programs added
    recently.
    All was normal up till last weekend --- for some weird and wonderful
    reason, I'm thinking Registry Mechanic might have titled something, but
    when I did the Restore, still nothing changed.
    I tried to do a System Restore, but I kept getting an error at that
    point, that wouldn't allow me to go back before the problem began.

    Say on O wise one if you've advice

  6. Ok I understand what you mean now.. If you go to the task manager and
    organize the processes by CPU usage are you able to see what exactly is
    using the processor when these spikes occur? Or is it unclear what
    causes the spikes as you watch this list?

    ps don't anyone even ask why I have 96 processes open. Yes there is a
    reason :p

    Here's what goes Brian --- I see Opera only is only using 204, 624
    memory / I see that Norton 360 is going back and forth a bit but not
    very high and not very much.
    The svchost.exe is a mere 86,600 --- these are what is presently
    standing out to me.
    From a professional perspective, say on sir ---

  8. I believe you are looking at the memory usage, we are more interested in
    processor usage. Click on 'CPU' box I circled in that picture so it
    organizes the process from highest CPU usage to lowest CPU usage.

    When the box near the bottom that reads 'CPU Usage: #%' spikes up to
    50% or whatever the number may be, try and see which process is now on
    top of the list [which should be constantly reorganizing itself].

    Ok, sorry about that. What I've watched go up just a bit is Diskkeeper,
    but my question is --- why now? Why hadn't it been doing it before.

    I'm off to a meeting, but I'll watch this again and see what happens.
    I'll get back to you in a bit and thank you a million times for your
    help. I'll touch basis with you shortly and let you know what happens.
    Thanks Brian!

    cpu #'s --- up to 20 while cpu usage at bottom is 14-19% --- migh
    change, but again I'll let you know later!
    Let me know what you think

  11. I would continue to watch taskmanager a while longer and try to figur
    out if diskeeper is actually the cause for your processor spikes.. if i
    seems that it is, poke around in the options or settings in diskeepe
    looking for anything that could be causing it to use your laptop when i
    is idle [maybe constant/automatic defragmentation, or something lik
    that]

    I have never used diskeeper, so we can go from there if you are able t
    narrow it down as our problem

    I am doubting myself that this is best course of action though. I
    makes no sense that your fan is suddenly acting up in response to this
    since you say diskeeper was not recently installed or changed

    It seems like a silly suggestion, but are you using your laptop in a
    especially warm or stagnant area when the fan acts up? Are any of th
    intake or output vents blocked

    Also when the fan speeds up, about how long is it before quieting bac
    down again? Seconds? Minutes? Different each time

    You could also check Toshiba's website for a BIOS update that applie
    to your specific laptop model; although the chances are incredibly slim
    a BIOS update could help solve a fan controller issue

    If anyone else has suggestions for ripsnort or criticism for me, be m
    guest. This could be caused by a pretty wide variety of things

    Thanks again Brian. I did disengage Diskkeeper from automaticall
    defragging, but like you, I really can't believe that's the culprit
    I've had it set on automatic for the past year, and I can't recall i
    causing problems before.
    The fan does not run continously, but in spurts --- it has for the pas
    few days, run fairly quiet then up goes the cpu usage, and the fan spin
    up. Then it will quiet down for a bit --- sometimes it will go on for
    bit longer but not continously.
    I'm not in a stagnant area, but quite open and not overly warm.

    I did have this same snag a few months ago, but I did a system restor
    and it seemed to clear. This time, the system restore wouldn't restor
    to the day before this problem resurfaced.
    Now I did notice this since I came back home tonight --- the fan ha
    not been turning up, but been rather quiet, except for a few seconds
    and this is what I caught on the taskmanager --- something calle
    "mcupdate" and sent the cpu on the taskbar up to 34-47-51 then i
    disappeared and the computer's been quiet. It's running at i.e. 2, 7, 2
    6% --- I'll keep watch on it and let you know if I find something els
    totally weird and wonderful.
    Again, if you've something for a suggestion, I'm listening

    Ok Brian, this is what I'm finding out about mcupdate. It's something
    apparently that's to do with Media Centre, so I've gone into Task
    Manager, found it, disabled it --- at this point, all is quiet on the
    home front.
    -Now tomorrow morning, should I gallop into this study and find a hole
    in the roof where the laptop spun off into space, I'll be hurling myself
    out through the basement window in despair!!! -
    *-_But_-* if it's quiet, you're going to have to stand up and take a
    bow, for I'm going to credit the beginning of the ending of this episode
    to yourself.
    Stay tuned to a computer near you for the exciting conclusion to "As
    the fan turns" ----------

    Well Brian, for a moment or two, there was a point of ecstatic joy, bu
    for some strange reason, that is fading fast.

    I see the cpu still spiking, say from 1-4% to 30% --- even if it goe
    up 4-5%, the fan will go up with it.
    The only thing I can see from the Taskbar is Opera that's usin
    anything, but really nothing to speak of. The System Idle is always i
    the high 90's, but it remains that high even when the laptop is quiet.

    Even as I type this, the cpu is going from 2-7% and along with the fa
    humming the tune of whatever.
    If the computer is not being used, it's quiet, but typing, scrollin
    through Opera (or Firefox) this puppy is up and down with the fan spee
    coinciding with the cpu usage whether small or larger.

    So, the exciting saga continues unfortunately. Hopefully yourself o
    someone else has something they've seen before and found a solution fo
    it

  16. I agree with Max - the little bit of CPU spiking is completely normal and to
    be seen on any system.

    I think the problem is with the fan and/or heatsink. For some reason the
    CPU isn't being adequately cooled, so the motherboard is having to boost the
    fan speed even when the CPU is doing just a small amount of work.

    My guess it that it's choked with dust. Or maybe the thermal paste between
    the CPU and the heatsink needs renewing. But the former is far more likely
    (indeed, quite common in a laptop).

  17. Blowing out dust with a compressed air is a possible fix.
    But the OP should be aware that replacing a fan in a laptop is not an easy chore
    and should be left to an experienced tech.
    I have done it on three laptop brands and had detailed instructions on each to follow.
    Still it required a magnification visor, a clean desk and careful attention to details and where you put the screws.
    You also find that each make and model requires proprietary fan hardware.
    Buy the hardware before you start the disassembly.

    The Max, I've heard a fan bearing when it's ready for the heap. Thi
    laptop is not it. A bad bearing will be consistently bad. This is not.
    I've another new laptop here, and have heard while under stress, th
    fan spin with the same sound as this.
    The difference though, is this one presently is up and down, an
    coincides with cpu usage.
    But is it normal? No. If it were, it would be doing this all the time
    This only began a week ago. Had the same event take place a few month
    back --- did a System Restore and presto --- all was well.
    Thanks for coming in on this. Have you anything else up your sleeve

    Thank you also Steve for your thoughts. Interesting thoughts from bot
    you & Max.
    Spiking doesn't concern me, knowing as you say, it is normal. But th
    reving up of the fan now and then does.
    As stated to Max, a bad bearing is consistent, at least from what I'v
    seen before. This is not.
    But then again, I couldn't say with 100% confidence that you both ar
    wrong either. If nothing else comes up for help on the forum(s) I'll le
    a Tech check this.
    Have you come across anything quite like or exactly like my proble
    before

    My Dell Desktop did something like this right out of the box. It would be
    nice and quiet and then without any reason, the fan would rev way up-- and
    it was extremely loud. Did this intermittently, called Dell and they
    replaced the computer. the new one was and is still very quiet.
