Need help with CPU

[Thornet]

I got a new PC today and it made a weird buzzing sound. I assumed that it was because of one of the fans, so I downloaded Speed Fan to check my different components' temperature. While the others were normal, the CPU temperature was ranging between 80 and 90 degrees. Thinking that it might be an error, I downloaded a bunch CPU temperature measuring programs. Unlike Speed Fan, they showed the individual temperature of each core. The only one that showed a high CPU temperature, expect for Speed Fan, was Open Hardware Monitor, but it also showed low, optimal temperatures for each core. So I'm confused, is the high temperature an error or what? Here's a screenshot:

80c is on the high end of the processor under load. I am going to guess that it is a bad reading but the HSF (heatsink/fan) may have come lose on shipping. Check to make sure that all four corners of HSF are seated.
