What temp. should i trust?

My motherboard says 65degrees, but i have installed a sensor directly on the side of the cpu ( socket 775) i says 49degrees.

It must be my attached sensor right?

  1. Quote:
    The sensor won't tell the actual CPU temp, since the CPU is covered by the heatsink, so it can't tell you the precise temp. The mobo says a more accurate temp.

    Anyway, both temps are fine, you're not in a danger zone by any means.

    Right, the motherboard sensor should me better. However, 65°C is good only if it's @ full load :D
  2. If you're not happy with your CPU temperature. Then try to change the thermal paste with a better one and reset the heatsink properly back into place. If the CPU temperature remains the same then it should be ok.

    I have the same issue with my P4 system when I replace the heatsink/fan, I was not able to place the heatsink properly and the temperature 7 degre higher than the stock.

    So you might have to double check on that or check your CPUs thermal spec, it might be that is normal as well.

    engineering defect in stock Intel heatsink/fan units
    for LGA-775 socket CPUs

    (This generic message only applies to
    Intel CPUs with LGA-775 socket and
    stock Intel heatsink/fan units.)

    The problems with high CPU temperatures
    are most probably the result of improper seating
    of the stock Intel heatsink/fan unit ("HSF").

    That heatsink and fan do dissipate heat quite
    adequately, as long as the HSF maintains
    enough downward pressure on the top of
    the CPU chip.

    However ...

    the 4 pronged fasteners are not gripping properly,
    and this results in less downward pressure on the
    top of the CPU chip: less downward pressure
    translates directly into higher CPU temps.

    Also, the fasteners are made of a material
    that appears to be "creeping" after many cycles
    of heat and cold, which further reduces the
    downward pressure on the top of the CPU chip.

    A short-term solution is to unlock and re-lock each
    fastener, while pressing down with your thumb on
    the fan housing directly above each fastener.
    Doing this one thing reduced our CPU temp from
    140 F. to 100 F., which helped isolate the problem.

    Best solution is to switch to a superior HSF
    with a proper backing plate. We prefer the
    ASUS VR Guard Series, because of its superior
    engineering for cooling the voltage regulators
    on recent high-end ASUS LGA-775 motherboards.

    These photos show evidence of improper seating
    on a recent ASUS motherboard with stock Intel HSF:


    Also, Intel's Thermal Interface Material ("TIM")
    is too thick from the factory, which also results
    in improper seating i.e. all 4 pronged fasteners
    do not "lock" properly, even when applying a
    lot of downward pressure on each fastener.

    This TIM should be removed and replaced with
    a razor-thin layer of Arctic Silver (or comparable
    thermal paste) -- NO OOZING PLEASE!!

    I hope this helps.

    p.s. If you purchased your computer from a company
    that uses Return Merchandise Authorizations ("RMA"),
    you should start a new RMA so that this defect and solution
    are reported formally to your supplier.
