I just put together my pc a few days ago, and I used a used kraken x61. The computer turns on and runs just fine, but when I take a look at hardware monitor, I'm seeing that multiple cores are hitting over 100c, while other cores are staying around 35c. This is all while idling. I'm not sure what is the issue, I've reseated the cooler, reapplied the thermal paste, but still no luck. The processsor is an i7 5960x.
