newbie question - how to read temerature

[Isaac Mushinsky]

I have Dell Precision 530 2x1.7 gHz Xeon. Trying to replace the Dell's noisy 
fans I wanted to make sure the CPU temperatures are normal. But I can find no 
way to read the temperatures at all. ASL dumped with acpidump does not 
compile.

So as not to run too much text in the mail, here are the outputs:

(compiled with ACPI_DEBUG)

dmesg: http://omsk.mushinsky.net/acpi/dmesg
acpidump -t -d: http://omsk.mushinsky.net/acpi/asl
iasl errors: http://omsk.mushinsky.net/acpi/iasl

finally, 
$ sysctl -a hw.acpi
hw.acpi.supported_sleep_state: S1 S3 S4 S5
hw.acpi.power_button_state: S5
hw.acpi.sleep_button_state: S1
hw.acpi.lid_switch_state: NONE
hw.acpi.standby_state: S1
hw.acpi.suspend_state: S3
hw.acpi.sleep_delay: 1
hw.acpi.s4bios: 0
hw.acpi.verbose: 0
hw.acpi.reset_video: 1
hw.acpi.cpu.cx_supported: C1/0
hw.acpi.cpu.cx_lowest: C1
hw.acpi.cpu.cx_usage: 100.00%


Is it possible at all to monitor temperature on this box? If not ACPI, is 
there some other way? Dell's BIOS setup utility does not provide temperature 
either, so even at the cost of rebooting I cannot tell what it is. Sorry for 
dumb questions, I have never had to deal with this before.

Thanks for any help,
