Intel I5-6600k temperatures

Hello, I just upgraded my CPU, motherboard and case to I5-6600k , Asus z-170 progaming and Zalman Z11 and decided to play abit with the OC. My GPU is a GTX 970 g1 gaming.

I managed to get 4.5 GhZ with 1.3V and ran an Aida stability test for 34 minutes, screenshot here: https://gyazo.com/4d341b5b5d237580acb5586740b99bd8

I'm using the evo 212 for CPU cooling.

Recently I played dark souls 3 on max settings, and my temps went up to 71-76 max on every core after 2 hours, unfortunately I don't have the screenshot ( measured with HW Monitor ).

Are these normal temps? Should I reduce the voltage / frequency for every day use?

Temps are fine. You still have some thermal headroom.

Run it and have fun.

Thanks for the reply!

What is the temperature I should worry about my CPU life from? Or the one that it should never reach?

The CPU will throttle itself at 100C. Keep it at 90C while stress testing and all should be well.
