What it the maximum core temperature for the Intel Core i3-2130?

Hi!

I have Intel Core i3-2130 processor with box cooler, installed on Intel Desktop Board DH77DF.

And I found that during stress test CPU Core temperature raised to 80 degrees of Celsius (176 degrees Fahrenheit) in 10 minutes.

I used "CPU Stress Test" in Intel Extreme Tuning Utility. I ran stress tests with default BIOS settings.

So, I'm wondering if this temperature is normal for this processor or not?

I didn't find "Maximum Core Temperature" in the specification, only "Tcase" which is 69.1 C.

I will really appreciate all you thoughts and ideas!
