I have just been slightly confused about which aspect of the i5 chip I should be paying attention to. For example, should I concern myself with the temperature of each individual core of the cpu(an intel core i5 2400) or the cpu temp overall. I've been using speedfan, and realtemp, also HWMonitor to look at all the temps. Usually each individual core idle: 38-42 and under load it stays between 55-60 normally although sometimes an indivual core can jump to 65 but it quckly drops back down. Or should I be paying attention to the overall Cpu.
