Huge difference between BIOS and Real Temp

I have an i7-860 CPU on an ASUS MAXIMUS III GENE mainboard. Real Temp tells me my CPU temperature is around 50 degrees celcius while the BIOS says it is 95 degrees. The fact that the system runs stable under load suggests that the Real Temp temperatures are correct. But why is the difference so huge? A BIOS update did not help either btw.

That's why nobody cares about BIOS temperatures. :D
Trust what your core sensors says and that's all.

Bios temperatures and TCase temperatures in Windows can be very inaccurate. That's the reason why Intel introduced on die core temperature sensors so they would have some control over their CPU and so they'd know exactly when to trigger thermal throttling and thermal shutdown based on what the core sensors are reading. Many Tcase readings aren't too bad but without doing some sort of calibration, there's no way to know for sure. Of course if the bios says 95C at idle, then you can be pretty sure that it is wrong.
