I have my 7700k overclocked at 4.5ghz and i have the kraken 52 cooler my temperature are at 30-34c at 5% load. Is this the norm?
Depends on the temp inside where the PC is.
You don't check the temperature at idle you check it under load.
Download OCCT and run it to stress the CPU that is how you check the temp.
It hits 97c in prime95 and intelburn test.
That is way to hot. That is actually thermal throttling.
Something is not right.
