Alrighty. My Athlon 64 3800 Newcastle is running at 19 degrees idle. I am using stock cooling, in a full sized steel case (aerocool) with pc wizard 2005. And it isnt overclocked at all
lol u might have a temp problem if its reading that cos thats really low for stock (eg my stock temps are 26 idle and that is generally quite low) but do u have stock cooling or som thing better
Where have you gotten this readout from? 19C is perfectly acceptable but considering my stock temperatures on water on a 3200+ didn't idle below 25C, you are having some temperature probe problems.
If your could provide the ambient room temperature that would be nice. That is a bit high for an Athlon IMO, but it isn't bad. A CPU can operate at temperatures as high as 70C and I wouldn't get too concerned until the load temperatures start hitting 60C.
Even so, the BIOS should have a temperature shutdown override that will probably be set at 70C, meaning if your CPU reaches this temperature, the computer will be shut down for safety purposes
