When I see that, it makes me thing i'm not wrong at all...
Your're not. Regardless of how well (or not for the acx 3.0 :-p) the cooler works, all items - core, VRAM, VRM etc. are cooled to some degree, just at different ratios. As per the link, playing BF1 with 90% fan and 55% TDP , VRM was 8°C hotter than core (53°C). Furmark 90% fan and 100% TDP, VRM is 17°C hotter than core (71°C)
55% TDP, VRM is approx 115% core temp
100% TDP VRM is approx. 124% core temp
Makes sense I guess that the efficiency is dropping as VRM temp is increasing...
