I replaced the TIM and thermal pads on my reference Vega 64 for Thermal Grizzly stuff. This is my totally unscientific back of a cigarette box before/after data, tested on BFV on toughest graphical map (Twisted Steel) at roughly same ambient temps:
Stock TIM/thermal pads:
Max GPU Diode: 68c (Average: 59.6c)
Max GPU Hotspot: 83c (Average: 74.8c)
Max GPU Memory: 75c (Average: 67.3c)
With TG Kryonaut + TG Minus Pad 8:
Max GPU Diode: 62c (Average: 54.4c)
Max GPU Hotspot: 81c (Average: 70.5c)
Max GPU Memory: 68c (Average: 61c)
So, there was a decent drop across the board, give or take a bit for variations in my totally not scientific testing. However, hotspot remains relatively high which what I was aiming to reduce.
Thoughts? I don't have enough stuff left to reseat and I think perhaps that is just the limitation of the chips heatspreader and there isn't much more TIM can do (in terms of high hot spot). Then again, perhaps I am over stating how bad the temps are?
EDIT: The grand question, was it worth it?
