I was just wondering if anyone can tell me why 2 of my CPU cores always run 5-7°C hotter than the others? This always happens, even with the CPU under 100% load. I replaced my cooler with a Corsair H80i about 6 months ago and used the pre-applied thermal compound that came with the cooler. My CPU is oc'd to 4.2GHz. I would really appreciate some advice, thanks.
