Hello, I have purchased and installed an intel core i7 3770k and also installed a cooler master hyper 212 evo cooler. The system works greatly but in core temp I have noticed that while not doing anything (ex. sitting on desktop) core1 core2 and core3 have an average of 34C and core0 has an average of 40C. Is this something I must look into or it is natural for core0 to have higher temperature?
