So far, there are NO system health applets that approach the utility and
accuracy of that old favorite, MotherBoard Monitor. Unfortunately,
MotherBoard Monitor has not been updated in several years; consequently it
does not work on Core 2 motherboards. SpeedFan may work on SOME
motherboards, but certainly not on yours (whatever it is - posting WHAT
motherboard you have would be a big help in getting help, as would the
ambient room temperature and the type of cooling you use).

SpeedFan 4.33 reports, for my EVGA 680i, core temperatures that are 10 to 15
C below the actual temperatures (as reported by the Intel Thermal Analysis
Tool. SpeedFan 4.34 beta 37 does a much better job; the core temperatures
are accurate, but system temperature (at - 65 C) is off a lot, only two fan
speeds are reported (one of which is NOT one of the existing fans!) out of
four, and of the three voltages reported, the + 12 volts is low by about 1.0
volt (at 11.09 v).

You should use the Intel Thermal Analysis Tool for accurate core
temperatures (TAT reports on at least 2 cores.)

SpeedFan works better for some motherboards than for others - that likely
explains the difference you get on your two different systems.

Intel Quad Core CPUs produce more heat than Core 2 Duo CPUs. That is NOT
the same as 'run hotter'. The core temperatures depend on heat produced,
the cooling solution and the room ambient temperature.
