You are right. That's my fault. I confused with wrong temperatures that the sensor gave me. I thought Temp1 and Temp2 were the cores 1 & 2. You can delete my post.

As you can see on screenshots the temperatures are a bit different. And Speedfan shows (on my opinion) the right temperature, because when the temp. of CPU become 80 degrees it starts beeping but in that case I can still touch the radiator on CPU. Please, correct this mistake.
