One of my favorite thermocouples for CPU testing is Omega #5TC-TT-K-30-36-SMP-M. They are available in J,K,T and E types, are 0.010" in diameter, and have 36" long 30 AWG Teflon coated leads (36 AWG leads are also available). I usually use the type-K but type-T are also available if you prefer. The -SMP-M designates a pre-wired miniature connector on the end. They cost $44 for a pack of 5 plus $25 to have the connectors mounted.

FWIW I use a jewelers saw to cut a narrow slot into the top of the CPU socket (edit) and Arctic Alumina epoxy (electrically non-conductive) to attach thermocouples to the CPU backside and/or core.
Good tips, thanks, and you're welcome.

I think I'm ready to take the plunge with this, but hold, pending funds. I'm getting a bunch of requests for testing, and I'm nowhere near ready to do it. Do you still have a source for those heaters?

I'll try out the Omega T type, as per pHaestus' recomendation.

Something crude but accurate could be built for less than $30.

A more practical option for most would probably be to buy a multimeter with a 4-wire ohms function. They are not uncommon.
I like that idea, thank you for that tip!
