Hello, Please can you send the dsdt.bin table, output of sensors-detect and lspci? Also what is your board manufacturer/model ? do generate the dstd.bin do: cat /proc/acpi/dsdt > /tmp/dsdt.bin > 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 Hmm this is bit strange. The CPU seems to be totally idle. > "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." This is something different. Lets find out from sensors-detect and dsdt table where does acpi take the infos. Thanks, Rudolf
