AMD K8 processor

Hello,

I am new to this Forum, so I would like to say hello to everyone.

I would be grateful for some advice. My computer is a generic x64 running a 64 bit dual core AMD K8 processor.

There appears to be an overheating problem with the cpu. After about 15-20 minutes of running the computer will automatically shutdown. After it had cooled down, I loaded Core Temperature CPU monitor. I ran a couple of programs, just to load the cpu. One of the cpu core temperatures quickly reached 125 degrees and subsequently shut down.

I unclipped the fan/sink assembly and removed all the existing thermal paste and applied a fresh coat. On booting up the computer it shut down again after about 20 minutes.

The PC has working PSU, case and CPU fans? Perhaps it is a faulty CPU? Has anyone else experienced a similar problem?

Many thanks,
Mark

  1. Possibilities;

    Dust Buildup,
    Too much thermal compound,
    Heat sink not properly seated,
    Heat Sink fan not turning at full RPMs
    Poor case airflow,
    Faulty M/B temp sensor,
    N/B overheating,
    Bad P/S,
    Hardware failure,
    Or all of the above.

    That may not help much but you'll have to go through a process of elimination until you discover the true problem, use as little thermal compound as possible and check the contact footprint for even coverage.

    Sometimes the heat sink fan begins to die and run slower, it appears to be running but not fast enough to properly cool.

    If the P/S is failing it could still boot, but not be supplying the power needed causing overheating.

    Good luck diagnosing the problem.
  2. Hello,

    Thanks for the suggestion.

    The fan and heat sink were cleared of dust and thermal paste before reseating.

    I have just checked the system and cpu temperatures/current cpu fan and system fan speeds:

    39 degrees
    84 degrees
    2350 rpm
    2600 rpm

    I think the fan speeds look sound, but I am concerned at the cpu temperature - 84 degrees celsius in bios.

  3. Try pulling the side cover and setting a house type fan blowing directly on the CPU area and see if the CPU temps drop?
