I have recently built a new rig, and upon running core temp, I notice I have a bizarre temperature discrepancy between the four cores on idle. The first two (marked c0 and c1 in Core Temp), fluctuate between 29 and 31 degrees. However, the c2 core maintains a temp of around 37-40 degrees. The last core (c3) is a little better, staying at 35-36, sometimes jumping to 38 at odd intervals. I used this processor in another rig with the same heatsink, a Hyper 212 EVO, and didn't experience such strange temps. Should I try reseating the heatsink?
