I'd like to buy a i7 8700 if I can find a good budget aircooler. I have a mATX and I don't want to change it because of the limited space where my pc is. And can anyone explain me how does the dynamic frequency scaling (threattle) works? Do I need to make something in BIOS or is it auutomatically? And one more question: Do I need a Z series motherboard for this dynamic frequency scaling? TY
