My 7600x Eco is constantly hitting 80C and getting throttled (by my motherboard setting) on an Arctic Freezer 36. It's already gone through per core undervolting by at least -20 on each core. It's not even hot at where I live.

Is this normal? Is it a CPU thing or cooler thing (remount and apply thermal paste? defective cooler)?

Gamers Nexus appears to have better results with their unit.
