hello,
i have a qx6800 cpu ( quad core extreme )
temperature monitor gives me this values then machine is idle

Coretemp does not measure temerature. What you get is "a number of something to trottling activation". This "something" depends of a temperature, but this dependancy is not guaranteed to be linear and is NOT calibrated to represent actual temperature in degrees centigrade. The only actual thing, which you can be certain of, is that your CPU is not being throttled while coretemp value is greater than zero.

If you still want to use coretemp, maximum for qx6800 is believed to be 80C, not 100C kernel reports. Your 74C (26 units of something to TM2 activation) is actualy 54C.

Maximum temp of 64C is measured in the middle point of the heatspreader, which has no connection to coretemp "degrees".

There is almost always another monitoring device on th MB, like winbond 83627 and Co, their drivers can be found under "Hardware monitoring support" section in menuconfig.
On pentium4 and above there is one more sensor, a thermal diode, which is located somewhere on the chip. It IS calibrated so it shows real temperature.
Of course, there's always the right way to do things

Does the heatsink feel warm?

If it's really 74C die temp, and the heatsink is properly attached, it should feel quite warm. If your heatsink is still cold to touch, likely the measurement is wrong or heatsink not attached properly.

When you first boot the computer when the machine is cold, is it that high?

My Q6600 reports low 50s with coretemp when idle for all 4 cores, and 40C with the thermal diode (measured with the onboard it8718 hardware monitor chip). This is with the stock Intel heatsink that came with the processor.

i was able to get the reading from the other sensors on the motherboard following this thread ( i have a asus p5q mb )
