• Overheating Issue

    From Barry Martin@454:1/1 to All on Sat Sep 14 11:27:00 2019

    Hi Folks!

    Turned on the monitor this morning and - nothing. Computer was off. I
    leave on partially because of overnight jobs, partially because of turn
    -on surges, etc.

    Power up; runs a while then shuts down. No fan revving, no warning,
    just off. (Great!)

    Open the case -- little dusty in there for as new as this machine is.
    Power on; all the fans working. Good, but odd - figured I'd see a dead
    CPU fan. Shut down, let come to room temperature, spray with an air
    duster, let come back to room temperature and retest. Also ran psensor
    to see if anything telling there - guess normal. Nobody too hot. Let
    run for a while - no shutdown.

    Put the cover back on and back into position (where the computer
    normally is). Runs a while then shuts down. Of course!! Something
    with the cover on? But psensor didn't display any higher temperatures.
    Some utility I wasn't running before?

    Unplug and move the computer back to the work bench. This time happen
    to lay it on its side (it was upright - vertical - before): bleah! Bunch
    of dust over the guess intake for the PSU's 120-140 mm fan! Blow that
    out. Retest, put back where it belongs. That seems to have been the
    problem!

    So a combination troubleshooting tip and question. If have an otherwise random/no reason to shutdown issue check the bottom of the computer!
    This case has the PSU at the bottom. Seems to make sense from a
    stability issue but mainly got the case because I liked what it looked
    like -- quite frankly plain black -- and had the specs I needed,
    including sturdiness; plus a low price.

    The question portion is anything I can do? The house has been dustier
    the past several years -- others experiencing and have read due to some vulcano erupting years ago. Vent filters on the computer could make air
    flow issues worse. And is there a way to monitor the temperature inside
    the PSU? Is an EVGA or Thermaltake PSU.

    TIA!

    More likely carpet getting worn and making more dust. That's the source
    of most of my household dust -- thick but well-aged carpet that both
    sheds and puffs, and the rest seems to come from the attic's cellulose insulation. Somewhat mitigated if I regularly vacuum the living crap out
    of the carpet. It's much dustier in here than out on my porch, negating
    the notion of volcanic dust.

    Also helps to change furnace filters regularly.

    Make high-airflow filters from pantyhose, or here I've used some very loose-celled foam (random piece that came as packing), or you could cannibalize household furnace air filters. Foam is probably the most
    effective as fine dust stopper, because it has so many convolutions for
    dust to get stuck in.

    Anyway, just cut to cover vents and fasten by whatever means is
    convenient. My foam filter sits under the half-a-box that I use as a
    noise reducer since Silver's case has a fan on the top. (Point noise at
    wall instead of at ear)

    I never thought of the carpet! The whole whole is carpeted, all older
    but in decent condition. Regularly vacuumed but.... OK, another
    mystery solved!


    Also helps to change furnace filters regularly.

    That gets changed about once a month.

    Thanks! I had another issue where the system started shutting down 'randomly'. No revving of fans (CPU and an added chassis fan are PWM);
    no revving fans sounds before. Minimal dust collected at the PSU,
    unlike before. Did find a collection on the fins of the CPU's heat sink
    so air dusted that out -- made sure to wait until the components were
    around room temperature before and after. Have seen and barely heard
    some changes in the fan speeds. CPU's fan rated 800-3000 RPM, PSensor
    says around 2500 RPM, CPU (socket) at 102øF (I knowwww: 41øC sounds cool
    to me!).
