"Core Temp" - CPU Temerature monitoring tool

[The Coolest]

I saw both CoreTemp & RealTemp are reporting the same temp for my i5-6600K.
But the temp of each core seem impossible it is nearly ambient temp.

Do I need to adjust some setting to have correct temp?

What is the TjMax? What's the temperature and does it change with load?
Skylake are pretty efficient processors, and I wouldn't be surprised if they ran close to ambient at idle if you have good cooling.
Another thing to keep in mind, the thermal sensors can become less accurate when temperature drops.
