i've noticed recently that individual core temps on my I3 have reached 75-80c when gaming, this has never ever happened before and i've even gone to as far as decreasing my core speed from 4.5GHz to 4.4GHz and still getting the same results, i have a cooler master Hyper 212 evo, so my cooler is decent at doing its job. Should i be worried at these speeds or not (cpu load when playing games varies between 70-100% usage)
