    The shims exist for one purpose, to help keep from getting the heat sink
    on crooked and thus cracking the CPU core. AMD provides a set of rubber
    bumpers on every current CPU for which this is a concern which serve the
    same purpose as a shim. There is no reason whatsoever to use a shim
    unless you have lost one or more of those bumpers on the particular CPU
    that you are installing, and if you are a careful worker precious little
    reason even then.

    How useful or necessary are shims for installing an AMD CPU?

    I've installed AMD CPUs in the past, without too many problems, but
    the thought of an extra safety net sounds good to me.

    The trouble is, the only store I've found that sells them is telling
    me to avoid them as they can short out the CPU. Is there an
    alternative to the Thermaltake copper shims that won't risk shorting
    out the CPU?

    what are shims ????

  4. They're useful to the seller's financial bottom line.
    Shims came into existence when early Socket A users were destroying CPU's by
    improperly installing HSF's and/or using HSF's not properly designed for
    Athlon/Duron CPU's. The idea was to prevent the installer from exerting
    pressure on the edges of the CPU die, causing it to crack. Later, myths
    surfaced that shims somehow helped cooling.
    Shims (made of conductive material) *can* cause electrical shorts if not
    designed properly for your model CPU, or if improperly installed. Shims
    won't help your cooling, and may add to heat problems. Anybody who can read
    instruction and who exercises due care can mount a HSF on an Athlon without
    breaking anything.
    Bottom line: waste of money.

    I would guess they do help cooling
    Help to cool that hot heatsink and deliver some of the heat back into the
    edge of the chip package :)

    Thanks. I guess I won't bother getting one.

    Sounds like these things are obsolete.

  8. Never demonstrated in any unbiased test. AAMF, they restrict airflow around
    the base of the HSF and edges of the die, sometimes causing temp increases.

  9. I need to correct my previous response :)
    Should have said: I've never *seen* an unbiased test showing a shim
    improving cooling.
