This is a laptop with a tiny fan and 53º C while processor is idle is understandable since cooler is on passive mode
most of time. But 73º C looks way too much for me.
this for me seems the thermal zone, and not the core temperature...
anyway, install a monitoring daemon (kima for kde is very light/good and integrates into the kicker) or any other like ksensors or others (i don't know the gnome ones since i completely dislike gnome but there are a lot of superkaramba widgets to do this) and see there your effective temp.
there you should see:
the core temp. mine turion 64 single core go from 30-35° idle to 60-65° C when at max speed and max load.
the thermal goes from 58° when the fan starts to 75° when the processor goes in passive mode decreasing speed for avoiding overheating problems. at 105 it shuts down.
now, i've heard that dualcores can have a temp of 5 to 10° higher than the single cores, but i don't know if this is really true.
anyway, how do you know that that 2 devices are effectively the processor?!
your problem is that acpi doesn't get the processor states. if it doesn't provide you with trip points in /proc/acpi/thermal/thrmx/trip_points then you have an acpi problem. this may be caused by bios or by wrong kernel config.
make sure that your thermal is compiled and started and that your bios is ok reading and doing this:
http://gentoo-wiki.com/HOWTO_Fix_Common_ACPI_Problems
the steps needed are the ones till you recompile the dsdt and see if the compiler raises errors. if it does then you might have a bios problem. try to fix it according the infos there and recompile.
if the bios is ok or the fixed one doesn't make the processor work with the latest kernel then search on the
kernel.org the acpi bugzilla or the mailing list and report there your problem. they could help you fix it or they could patch the actual acpi to make this work.
if you have an acer notebook, this might be the problem, since i've encountered many acer laptops that don't read the thermal correctly.

Hello everybody,
I own a Turion64 X2 1.8Ghz and I have my k8 sensor module for getting CPU temperatures.
I wanna ask if these temperatures looks OK to you.
Temperatures while compiling stuff with both cores @ 1.8Ghz and 100% usage:
# cat /sys/devices/pci0000:00/0000:00:18.3/temp1_input
67000
# cat /sys/devices/pci0000:00/0000:00:18.3/temp3_input
73000
Temperatures while idle:
# cat /sys/devices/pci0000:00/0000:00:18.3/temp1_input
46000
# cat /sys/devices/pci0000:00/0000:00:18.3/temp3_input
53000
This is a laptop with a tiny fan and 53º C while processor is idle is understandable since cooler is on passive mode
most of time. But 73º C looks way too much for me.
Also my ACPI doesn't provide me any thermal information and doing so I have no
processor trip_points to get system rebooted or processor throttled if temperature is too high.
Also when booting linux I get this:
ACPI Exception (thermal-0311): AE_BUFFER_OVERFLOW, No critical threshold [20070126]
I made a simple daemon to scale cpu frequency in case temperature exceeds a predefined threshold.
Although my question is if these temperatures looks correct and I should trust them.
My room temperature is 21º C.
