Let’s first isolate the data into groupings of an individual TIMs and look at the specific mount data. For reference, the dashed line is the discarded mount and is not included in any of the averages.
IC Perihelion has so little response, visually, to contact that it’s a serious concern. The Great Contact contact image used here was the only one of fifteen mounts that looked different; it was also the best mount of the fifteen. As for the cure, it seems to get noticeably worse as time goes on with Poor and Moderate Contact, which is a concern (when does it stop? there is no theoretical limit to performance degradation).
Noctua NT-H1 responds very well visually. It does, however, have a noticeable amount of cure overall.
OCZ Freeze does not have much visual response, only barely thinning as contact improves. It does not have much of a cure
