My computer will turn it self off because the core temperature keeps raising to high. Its only does it when ever i use high CPU usage stuff like games and burning programs.When im not it will sit at a good 25 degrees. I knows its not a ventilation problem because i have cleaned the case of dust, i have many fans,i replaced the cpu fan with a brand new Blue Orb II, i applied new thermal paste/grease.I dont know what else to do
