You may want to try Hmonitor, maybe it helps.
I'll download everest and try to help out
EDIT: ok downloaded, looked around. only thing I found was hit refresh then hit the "report" button. then a window pops up and just hit next -> hardware-related pages -> HTML -> finish.
this will run diagnostics on your machine. scroll down and temperature is there. unfortunantly, I don't think the temp is constant, it just shows what it was when you ran the test. sorry can't help out any more. try hmonitor like I said above.
everest seems neat to tell you what you have running though.
