Vacuuming Tool?

  1. Remove the fan from the heatsink.

    Adding RAM(*), I discovered dust down in the fins of the CPU heat
    exchanger.

    Fan blades too closely spaced to get a standard vacuum tool to reach
    the fins.

    So I improvised, using a soda straw held into the opening of my Dust
    Devil hand-held.

    Worked, but somewhat a PITA.

    Anyone know of tools made for the purpose?

    (*) Found the cause of my peculiar crashes... when you run out of RAM
    XP doesn't respond gracefully.

    With Windows Explorer, Eudora, Agent, and The Calendar Planner open
    I'm now using 555MB out of 982MB available... No wonder I'd get a
    crash when I had only 512MB and then tried to open Excel as well ;-)

    I wonder if anyone has put an open case computer in a dish washer?
    No soap of course. :)

    Isn't dust like this typical blown out with some compressed gas?
    I think one product is called Super Duster.

    I prefer to suck the dust out of there, rather than risking pushing it
    deeper into the fins. (This particular box has a duct from the side
    of the case, where air is sucked in and *pushed* thru the fins.)

    That's a pain.

    I think I'll construct an adapter to fit an ABS irrigation feeder tube
    to the vacuum, so I can reach down in narrow areas.

    something wrong with your swap file then.
    did you by any chance turn it off? or are you short on Disk space?

    Hardware stores around here sell different sizes of Brass tubing that
    you can solder. i would be concerned about using plastic tubing while
    sucking air and Dust through it. i've see it create static charges and
    if you happen to slip and touch a component on the board. well., you
    know the rest of the story. of course there is also static free plastics.

    Not that I know of. Looks like I've left everything there as default.
    Nope. Using 21GB out of 80GB available.

    I never had such peculiarities until I moved "up" to WinXp Pro from
    Win2K. I'm sorry I ever did that.

    True. My local Ace Hardware has a large display of "craft" brass
    tubing of all sizes.

    Which would suggest using a flexible rubber tube down to a tapered
    brass nozzle. That'd work.

    XP with windows explorer, Outlook, Google, LTspice, MPlab.
    Total commited = 230MB. (I think I've 250Mb fitted ).
    Only memory probs come when the obnoxious window "helper" thing decides to
    load itself.

    Hmm, well this box i'm currently on is a W2k and it's been nothing but
    smooth sailing here.
     
  13. I think WinXP is still susceptible to cumulative memory leaks. It seems
    like it gets bogged down (and even refuses to do some things) after it's
    been running for several days. Then when I try to shut it down, it hangs
    until I tap the power button, then it sometimes hangs again until I do the
    5 second power-off reset. Then it's usually good to go for a while again.
    Well behaved programs probably don't cause memory leaks, but I do
    programming, which sometimes results in access errors and memory leaks when
    debugging. It's a lot more stable than WinMe, however!

    Same experience here. I never shut down until it hangs. Then I often
    have to resort to the reset button approach to kill it.
    But less stable than Win2K in my experience.

    The PSpice machine with Win2K Pro, AMD CPU, NEVER hangs or crashes.
    Only reboots needed are for program installs.

    I think the box was better in the off state than trying to use ME! :)

    Jim, did you try canned air? I immobilize the fan then blow the dust out.

    On an old Vaio laptop, the pads between the GPU and the CPU to the fan
    duct had both dried out. The result was excessive heating and system
    shutdowns. A shot of thermal grease, appropriately placed, solved the
    problem.

    My new Alienware PC has a reset button! And a bios option, set by
    default, that makes the power button work instantly. PLUS it has a
    real AC-line power switch on the back.

    DIE, Windows, DIE!

    And it does look like XP should be rebooted often, daily or so, to
    reset accumulated damage. At least it comes up pretty quick, 30
    seconds or so. 2K took minutes.

    Have I mentioned lately that all things Microsoft are crap?

    The WAF of that method is usually not high enough because when you blow
    the dust out it sails off onto other objects around you.

    I'm going to Ace and buy several brass tubes, sweat them into a
    tapered nozzle with a small-diameter flexible rubber hose to the
    vacuum... in fact that suggests that automotive vacuum hose might be
    perfect because it won't collapse.

    Yeah, it's called an air compressor. Take the silly thing outside,
    and blow the dirt out. I do it to my computers every few years.
