My fan and waterpump are running at 100% duty cycle constantly but for some reason it won't go below 100C post-engine swap.
I believe non-M2 N55's do in fact target 100C, but as far as I can remember, my coolant was always pegged to 80C (with oil slightly above that).
TIA!

It depends on operating mode and ambient temps. If ambient temps are high enough sport+ always targets ~80C comfort mode is close to 100c.
I have the dme tables showing temp targets:
