Hynix vs samsung ddr7 temp difference?

Hi. Coming from amd i know they had hynix and samsung vram that difference was 2-3% more performance, with hynix 10-15c more vram temp, making the card run up to 90-95c with the hynix.

How is it with nvidia cards and temp differences? Tried to search but they not mention the temp. Would not like that the 5070ti reach 95c if it have hynix?
