Question for Wec Newall

[Michelle Newman]

Is it possible for an AMD athlon 64 3200 to run at completely different
temperatures depending on the motherboard installed in. The above processor
was originally installed in an Asus board with an evo 120 cooler running at
36 idle up to 50 at full load transferred onto a microstar board in same
case same cooler same case fans thermal paste double checked reseated
several times and still runs at 49 idle going upto 60 under load. it now
crashes out under certain graphic intensive games going upto 65 hence why it
locks up but nothing has been changed except the motherboard. It is not
overclocked and the memory is OCZ platinum and all the hard drives are the
same any help gratefully received

The motherboard controls the CPU's core voltage and the fan speed, both of
which control the temperature. The Smart Fan function turns the fan on and
off depending on the CPU temperature, it's certainly possible for a
motherboard manufacture to screw that up. If the BIOS doesn't know about
the particular stepping of a CPU it could, in theory at least, give it the
wrong core voltage.

I would try the following.

1) In the BIOS turn off the Smart fan function so that the fan runs all of
the time, this should make a big difference. However you shouldn't need
the fan when the system is idling so the problem might be the core voltage.

2) Update your BIOS to the latest rev, it's possible that your BIOS is out
of date.

One question, are you using the same case with both motherboards? The
airflow in the case can make a big difference.

Yes still using the same themaltake case everthing about the system is the
same except the motherboard what would you say is a sensible running
temperature for an xp 3200?

Assuming the same voltage to the CPU and the same core speed, with
everything else the same, it should run at the same temp. Check voltages,
fan speeds, etc. Upgrade bios.

You don't mead XP 3200, you mean A64 3200+ right?

My X2 4400+ idles at 30C and hits 40C with both cores running at 100%.
Your original temperature of 36 idle and 50 under load is reasonable
although a little high. Your current temp of 60 under load is much higher
then it should be.

Your heatsink is probably not as well seated as it was before. What I
would do if I were you is take the heatsink off, clean off the thermal
compound from the CPU and the heatsink using a solvent, and then apply
some fresh thermal compound and put the heatsink back on. The thermal
compound manufacturer will provide some illustrations about how much to
put on, make sure you use the right amount, more isn't better with thermal
compound.
