Thanks for the comments.
The fans really spin and controlled by a fan controler
The ambient room temp is 20C
I've turned the machine in different directions when running
No hardware changes i have made the last two weeks
I've installed Corsair link
The temps are still high. Maybe i have to reinstall the H100i!
