It seems not to be a hardware failure,because the temprature (I feel) is ok in BIOS setup.
I'm running the latest Archlinux +Kdemod (stable),before an update severval days ago which updated many core parts like kernel26, my laptop became hot! As the case before, CPU's temprature is around 49 `C when I surf the Internet, but now, it's 56`C and my keyboard is unbearably hot. I've taken every cpu freq measure mentioned on wiki to cool my CPU(before these measures the temp is 62`C). I've tested that the CPU temprature will rise to above 56`C even if I do nothing.
Anybody have some ideas?

My CPU is Pentium-dual core T3200, I'm using modules acpi-cpufreq, cpufreq_ondemand and cpufreq_powersave. It seems that my CPU fan runs slower when archlinux is running.

I have made the same experience.
Since kernel 2.6.28.2 cooling seems to be different. Fan spinned on at ~75°C and runs in a high speed without slowing down again or even turning off, producing a constant noise (although temperature goes back to ~31°C). With kernel 2.6.28.1 the fan did not turn off again, too, but it did spin on earlier.
Notebook model is Toshiba Satellite Pro L350, also a Intel Pentium Dual Core T3200.
I think there is now solution at the moment. It seems the hardware is relatively new and not yet supported very well.

I've downgraded my kernel to 2.6.28.1 but it doesn't help.

This can be fixed by appending this kernel/boot parameter:
acpi_osi=Linux
