I just installed the Honeywell PTM7950 into the laptop.
It has made a significant difference. Benchmarks straight after boot gave higher performance (I am now around the higher of the single thread cpu performance bi-peak). Dramatically more watts going into the CPU. Aughts air is actually hot now. And the PTM7950 is ment to get better after a few thermal cycles.
Not sure if the tech messed up the thermal past when he did the motherboard swap, or if PTM7950 is just awesome, but I am very happy.
Below test's with BIOS fan control & Hyperthreading on.
Benchmark immediately after boot:
Single thread cpu stress:
Multi thread CPU stress:
[edit]
And true to the hypothesis of the PTM7950 getting better after a few thermal cycles, am am now right at the upper end of single threaded performance for my cpu. (hyperthreading still turned off):

Turned hyperthreading off. Doesn't seem to be yielding any extra single thread performance, at the expense of multithread work. Going to turn Hyperthreading back on.
Fairly happy with my benchmark scores in general now. Around the upper end of benchmarks for my cpu type for single thread performance, and at compared to the world I am at 98% percentile for single thread performance, and jumping the the world maximum single thread performance benchmark score is only 17.4% higher than min. I feel the latter is pretty impressive from a laptop.
CPU can now draw around 105Watts under a multithreaded load, before swapping to the Honeywell PTM7950, this maxed out around 65W.
Bios Fan (Hyperthreading off):
Fan's set to max (64) in TPfancontrol, which is well higher than the normal maximum speed step (7), Hyperthreading off:
[edit]:
Hyperthreading on, BIOS fam control:
Hyperthreading on, fan set to 64 in TP fan control:
From these results seems like there is no reason to have hyperthreading off, and that the impact from changing the fan speed is within the margin of error of the tests (seems to worsen overall score, but improve single thread score).
Regardless, I am very happy with the outcome here. Putting in the Honeywell PTM7950 as resulted in about a 9% gain in single core performance with hyperthreading on, which is a level of performance I am pretty happy with.
