Does anyone knows what is the optimal temperature for the Athlon64
3000+?
It depends on what CPU core you have - 90nm Winchester or 130nm Newcastle
or Clawhammer. I've found the 90nms showing about mid-50s and 130nms about
mid-60s on high load.
I have a ASUS K8N motherboard and my cpu is at about 47 degrees C in
desktop but in games (such as Warcraft III) the temperature goes up
to 68 degrees.
What should I do?
Start by making sure that you have a recent/latest BIOS and version of the
software which reports the temp. How does that temp relate to the "system
temp" - about 30C higher? Personally I don't put much faith in the temp
numbers reported by hardware monitors... other than as a comparison against
previous results. IOW if you start seeing higher numbers than previously,
you may have a problem with dirt/dust and it's time for a clean-up... or a
fan is going bad.
If everything is working OK I wouldn't worry too much but do check your
fans and general ventialtion.
