The replacement pads have the exact same thickness with the stock ones. I got the information from MSI itself. The question is however, would the new pads function more effectively or not.
You're correct, the die consumes much of the total power and so dissipates the heat the most. It looks memory temps are not worrying but, still I want to increase its longevity.
But why I'm worried?
Because since I purchased this card, rarely like very very really I see checkerboard like squares on the desktop (never while gaming though) so I thought my card is more susceptible to vram failure in the near future.
