Laser temp probe directly to CPU and coretemp (pics)

[rge]

ambient-----Probe temp CPU--------Coretemp 95 reading
24C-----------28C (no pic)---------------18C (no pic)
24C-----------31.6C (pic)----------------27C (pic)
24C-----------43C (pic)------------------53C (pic)
24C-----------58C (no pic)---------------75C (no pic)
computer shutdown last coretemp read 80C, but mouse and desktop froze first, so who knows what temp was.

I positioned the monitor with coretemp at top left, so I could get a pic of both coretemp 95 and my laserpro directly hitting the back of the CPU (note water block is removed and hanging down).

I held the block on with fingers, booted, initial and final measurement I could not capture, camera pic delay too slow and temp rise too fast. The other two I was able to get pics of.

Clearly DTS (coretemp reads from) is either non-linear, or simply does not read accurate at low temps. I think it is possible that coretemp could be accurate at temps around 50C+, but no proof it is. I was adding 15C to temps thinking that was accurate, now I dont think that anymore.
