Tbh I will never understand the logic of monsters being immune to cold in hell in those fire regions.
You would think they would be immune to fire and would die from cold but no it is the opposite.
A bit weird 
Demons in Hell pour milk before cereal and put pineapples on their pizza.
Abandon all hope, ye who enter here!
I love pineapples on pizza

Most of monsters are fire immune and fire resistant in CS/RoF. 4 act is a real hell for fire sorceress. And very easy for cold sorcs. All that chaos knights and flesh demons immune to cold came directly from 8th (the cold one) circle - pretty obvious )))
I cant Unserstand why WE have physical imune Monsters in hell there are Not Ghosts But Hey im a melee and thats the Game. When i Hit hard with a huge Axe flesh ignores the damage.
