So it seems like the higher rpms the faster it gets heated up. On the way back which is mostly downhill the car stayed at 90c. Forgot to mention it did not matter whether the a/c was off or on.

I hoping it's the fuel air mixture or the fact that i advanced the timing to 8deg, but it's probably the radiator or a pulley on the motor which binding up and causes extra load (when the car starts up in the morning a pulley is making a noise) so may be it's that. It's going in Wed to have the fuel air ratio adjusted to the specified mark.
