Computer crash cause of gpu hot spot

All in the title, computer crash on high juice endgame strats, after gpu goes 100+ dégrées.. Only on Poe tho ! I have a lot of fans so that's not the problem here, besides my CPU stay very cool even on high stress.
My graphic card is an AMD Radeon 7600xt.
If anyone has the same trouble and fixes it, please, save m'y life :'D
