First of all thanks to all for helping me on this issue.
i had solved the problem, i believe the coolen inside the raiditor need to run abit about afew days. Now my CPU temp on idle is around 21-35c, at full load 50-57c @ ambient room temp is 28-32c.
Loh ya forgot to mention CPU is core i7 980x @ 4.2ghz.
but now got a problem, why is the program coreTemp RC2.0 keep saying my CPU is core i7 9110x? But CPUz show the correct CPU.
