Undervolting is not the solution to high GPU temperatures. Good GPU thermal paste, higher GPU fan speeds and good PC case airflow is what you need.

I had 4 GPUs in my PC for test and all of them reached 100 degrees because i have only 3 fans in my case 1 Front 1 bottom and 1 Front (2 intake 1 exhaust) even with open side panel and i cant afford new so..
