Seen it done here and there, and it would be a really nice tool to meter the temps of the IHS and extrapolate the core temp.

But at the same time...

Well, for one, that's the warranty gone. I mean most of us that would pop the ihs off don't care much about a warranty I suppose, but it just seems like it's an expensive hole that's being drilled.

Beyond that, is knowing the core temp critical?

If a phase or whatever system is cooling the cpu and working properly, the overclock is stable, and the temp that's being read is stable (unless it's simply not reading anything at all) then I'm not sure I see much point in being able to know accurately what the temp of the core is unless you're testing a cpu for it's exact response to a particular form of cooling.

Very nice for someone doing research, not really necessary for someone that just wants to overclock.

One of these days I'll be making another load tester for the power supply that's got a couple of features included with it, including a probe that's at 'IHS depth' and another that's on a secondary plate to simulate 'cpu core depth' but that's still only a simulation.

I feel, however, that once a relationship can be drawn between a particular cpu and a load simulator to determine it's actual wattage, then all of the susequent information can be extrapolated without having to drill a hole in every IHS on every cpu.

Just my thoughts on it.
