Hi all, I have a AMD Athlon64 3500+ socket 754 and reading cpu temperatures using the k8 sensor is totally useful (thanks Rudolf). My ACPI is buggy and reading CPU temperature from it, is a mess. More information about my processor: $cat /proc/cpuinfo processor : 0 vendor_id : AuthenticAMD cpu family : 15 model : 4 model name : AMD Athlon(tm) 64 Processor 3400+ stepping : 10 cpu MHz : 800.000 cache size : 1024 KB fpu : yes fpu_exception : yes cpuid level : 1 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 syscall nx mmxext lm 3dnowext 3dnow bogomips : 1602.36 TLB size : 1024 4K pages clflush size : 64 cache_alignment : 64 address sizes : 40 bits physical, 48 bits virtual power management: ts fid vid ttp Despite the K8 sensor my ACPI offers me two more sensors. $cat /proc/acpi/thermal_zone/THRC/temperature temperature: 55 C $cat /proc/acpi/thermal_zone/THRS/temperature temperature: 47 C Since reading cpu temperature through acpi causes a lot of interrupts. It's near impossible to get a working system with ACPI temperature readouts with high sampling rates (lost ticks). $cat /proc/acpi/thermal_zone/THRC/temperature && cat /sys/class/hwmon/ hwmon0/device/temp1_input temperature: 55 C 30000 I readed that: "Temperature known as TCaseMax was specified for processors up to revision E. This temperature is defined as temperature between heat-spreader and CPU case, so the internal CPU temperature supplied by this driver can be higher. There is no easy way how to measure the temperature which will correlate with TCaseMax temperature." So I logged some ACPI VS K8Sensor: "ACPI","K8" 51,28 52,28 53,28 54,29 55,29 56,30 57,30 58,31 59,32 60,30 61,35 62,35 63,38 64,33 65,35 66,39 68,38 73,48 74,42 75,43 76,43 77,46 78,44 79,44 80,46 81,48 82,48 83,48 84,49 85,50 86,51 It looks like the CPU temperature is more or less twice the K8 sensor temperature (?in my system?).
