Hey guys I just put together a computer with the i5 3570k and z77x-d3h motherboard. I know how to check my cpu heat from hitting del at the start up screen when I first boot but how do I check it like for example when playing games so I know if its safe?

install a 3rd party program that shows you such basic info and even more like CPU-Z and many others
