RK3399 CPU temperature. Xunlong vs Armbian

[kentAVR]

I use orangepi 4B.

 

I use console Ubuntu with kernel 4 from Xunlong And my CPU Temperature (by htop) is about 70°C

I use console armbian with kernel 5 (Governor = powersave). And my CPU Temperature is about 79°C

 

Why so? I want to get 70°C in armbian too.
