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_at_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
