I recently just built a new computer, and thinks have been going good so far, however my CPU temperatures are very hot. When idle, the temps are to my limited knowledge, fine, being around 30-40 C. However, when running games the CPU gets to around 85-90 C, and when I ran a Prime95 the temperature immediately shot up to 100 C. I have not overclocked, and I am not using the stock heat sink fan. I have a I7 4770k, and my heatsink fan is http://www.newegg.com/Product/Product.aspx?Item=N82E16835200034 if that makes a difference. Thanks for your help.
