(I had to read back, a bit!)
I was referring to Crane's idea of running an enamel wire, to stick a thermocouple behind the CPU.
The key point was brought up by pHaestus:

thermocouples are ok if type T but the K series are not so great. Take a look at that article I posted in my worklog a week or so ago for guidance on choosing a temperature probe.

There's also Since87's critical point:

The ONLY way to eliminate error with thermistors resulting from lead length, is to use a four wire (Kelvin) connection, where one pair of wires is carrying the current for the thermistor and another pair of wires brings out the voltage across the thermistor.
A four wire connection using 40 gauge wire, is likely to be better than a two wire connection using 24 gauge wire. Of course this doesn't do much for you if you are hooking up to something with no provisions for four wire readings...

Is such a device available for a reasonable price?:shrug:
