I need a cpu heat monitor that will work under windows vista 64 bit.

CoreTemp will work, but you need a workaround:

thanks workaround works great

get cpuid's HWmonitor. Works fine in vista 64, no workaround needed.

Ah, I didn't know about that one.. looks good. What's a bit strange is that it detects two Winbond chips, the second one mostly displaying spurious data:

W83627DHG
CPU VCORE 1.13V (correct)
+12V 11.93V (correct)
SYSTIN 38C
CPUTIN 28C

W83791D
CPU VCORE 1.07V (wrong)
+12V 4.13V (wrong)
TMPIN0 -37C
TMPIN1 40C
TMPIN2 36C

I guess the W83791D is best ignored, it gives mostly wrong or meaningless data.
