That seems quite high to me. With an uptime of a shade under 17 days, during normal use and with [EMAIL PROTECTED] running since 11.5 CPU-days (says top), /proc/acpi reports 49 degrees Celsius at the CPU. My system, built around an Athlon 64 3000+, has a critical trip (shutdown) temperature of 70 C and I have never hit that level. I have not checked the CPU temperature during lengthy compilations however, but considering that CPU utilization stays close to 100% due to [EMAIL PROTECTED], it is probably about the same. I would consider anything above 60 C as certainly out of the ordinary and worth investigating.

How are you monitoring the temp? through /proc/acpi/thermal? or just from the bios? Or are you lucky enough to have a readout on your box? I also am not an expert on AMD chips, but ~65C seems acceptable for an upper-level temperature to me. Unfortunately, the AMD documentation (http://www.amd.com/us-en/Processors/TechnicalResources/0,,30_182_739_7203,00.html) doesn't really specify what the throttle and shutdown temperatures are of the processor. They just say that the case temperature should not exceed 42C, and that Tcase_max is 70C. I am reading that as meaning 70C is the upper design limit for the processor. What does bother me, as Glen alluded to, is that you are not seeing a drop/rise in temperature with load. That indicates that maybe your kernel configuration isn't correct for the Athlon64. Double check your kernel configuration, and make sure you have support for the Athlon64 in your kernel. You might also try enabling CPU Frequency scaling with the ondemand governor and the Athlon64 driver. You could also post the output of dmesg. FYI, the pentium-m in my laptop idles at around 60C, but will easily reach 85C under full load. Fortunately, it doesn't throttle until 95C, and doesn't shutoff until ~105C. -Richard -- gentoo-user@gentoo.org mailing list

They are so much off the real value most of the time, that the only temperature that maters, when your box starts to behave strangely. Note down that temperature, and do everything to not reach it. But everything below that is nicecool. -- gentoo-user@gentoo.org mailing list
