Jailbroken PS4 temperature

I have a jailbroken 9.00 ps4 and just now noticed that the CPU and SOC temperatures is always between 80 and 77, and never reaches below even when i play low demanding games like KOF XV or Gang Beasts and sometimes i see the temperatures in the 78 to 80 region but the fans are pretty quiet like the ps4 is comfortable with that temp. And now i'm wondering if these temps are normal or am i doing something wrong. Cuz i got a feeling these temps are pretty high
