CHT temps

Hello all,

I have recently changed my oil cooler in new (150hours) rotax 912ULS as the temps were slightly high. Oil temps are now good but the CHT’s are higher than before (expected) due to positioning.

my engine has the newer CHT limit of 120°

my question is are these temps ok. Or should I be concerned and try to lower them?
