Heatsink glues. Too thick = bad

  1. Just a little heads up on heatsink adhesives.
    I have successfully rebuilt a discarded computer at work.

    When I started it, system and cpu temps quickly rose.
    So, I shut it off to investigate the heatsinks on chipset and cpu.
    I found;
    A 1/2 millimeter thick wad of black, gummy stuff under the Pentium3 600E's fan heatsink.
    Another 1/2 millimeter thick wad of gummy clear glue under the I810 chipset heatsink too, after I pried that off carefully.

    I scraped all that gunk off with a razor blade and isopropyl alcohol.
    Reinstalled the processor heatsink with thermal grease this time.
    Arctic alumina glued the chipset heatsink permanantly back on.

    The result is a much cooler running computer, able to do a better job discarding excess heat buildup and no more problems with it.

    Congrats. It's fairly common practice to replace generic thermal grease with premium thermal grease for better cooling. Often times modders will also replace the generic Heatsink and fan for more efficent versions as well.
