MacBook Pro 2011 overheating and screen WILL NOT turn on after sleep

bought a 2011 MacBook Pro. Put macOS Catalina Patcher and the computer works fine.

But when using the computer for a while (like watching YouTube videos) it starts to heat up. Is there a solution for this?No hardware modification has been done on this my MacBook Pro far.

I noticed that my macbook has the error (Screen WILL NOT turn on after going to display sleep).

Disable MacBook Pro Dedicated GPU was also done correctly as told you
