Thought I'd post up a couple handy appz for monitoring individual core temps of your dual core processors, these also work on some single core/core solo processors as well. These can be very accurate since they read directly from the die instead of a sensor on your mainboard
From Intel - "
TAT" - Core2 support only at time of this writing:

Screener
For all processors (including duals and quads) - "
Core Temp"
This is a new program that lets you monitor Intel's "Core", "Core 2" and all AMD K8 chips' die temperature. The temperature readings are very accurate as the data is collected from a Digital Thermal Sensor (or DTS) which is located in each individual processing core, near the hottest part.
