you do have a good point there, yes, the wire does compress a tad bit over time ( 3 months or so). The compression is finite, though.
I was however able to fit a STD AMD HSF to said CPU with no more or less fuss than usual, Sorry I don't have any experience with other after-market heatsinks, I'm just not the HSF kinda guy. I skipped that era completely

nun the less, I think the repeatibility of this method is just as good as say with a cut-socket method. Definitavely unrivaled in it's reliability as opposed to having the probe on top of the CPU, next to the core.
as for the OCability.... hmmmmm.... that might be, I am however not able to sense it, and as with all good things in life , there are always taxes to be paid........
