Hello people, I have a Dell XPS M1210 with Core 2 Duo (T7200) etc and I wonder if the temperatures that my laptop has with FreeBSD are normal .While idling it has about 62.5 C and on heavy load (qemu and compiling) I 've seen about 84.5 C.I feel I can boil an egg on my laptop.I want to mention that with debian I had before I 've never seen so big temperatures. Is there something I can do about that?AFAIK there is nothing I can do to use Intel Speedstep.I tried to use cpufreq module but it doesn't seem to work well. >marinosi@lucifer:~$ sudo kldload cpufreq >Password: >marinosi@lucifer:~$ dmesg | grep -i cpu >CPU: Intel(R) Core(TM)2 CPU T7200 @ 2.00GHz (1997.35-MHz 686-class CPU) >FreeBSD/SMP: Multiprocessor System Detected: 2 CPUs > cpu0 (BSP): APIC ID: 0 > cpu1 (AP): APIC ID: 1 >cpu0: <ACPI CPU> on acpi0 >acpi_throttle0: <ACPI CPU Throttling> on cpu0 >cpu1: <ACPI CPU> on acpi0 >acpi_throttle1: <ACPI CPU Throttling> on cpu1 >SMP: AP CPU #1 Launched! >acpi_throttle1: <ACPI CPU Throttling> on cpu1 >est0: <Enhanced SpeedStep Frequency Control> on cpu0 >est: CPU supports Enhanced Speedstep, but is not recognized. >est: cpu_vendor GenuineIntel, msr 6130c2a06000c2a >acpi_throttle1: <ACPI CPU Throttling> on cpu1 >est1: <Enhanced SpeedStep Frequency Control> on cpu1 >est: CPU supports Enhanced Speedstep, but is not recognized. >est: cpu_vendor GenuineIntel, msr 6130c2a06000c2a >est0: <Enhanced SpeedStep Frequency Control> on cpu0 >est: CPU supports Enhanced Speedstep, but is not recognized. >est: cpu_vendor GenuineIntel, msr 6130c2a06000c2a >p4tcc0: <CPU Frequency Thermal Control> on cpu0 >[...] marinosi@lucifer:~$ sysctl -a | grep temperature hw.acpi.thermal.tz0.temperature: 62.5C Could these temperatures be harmful for the laptop? Thank you all and have a nice day :D Ilias Marinos
