Exactly what I say but if you lower the fan tables where they start to work by 5C degrees it is better to change also thermostat open point by the same amount by changing it:

OEM thermostat opens at 88C, fully open at ~95C
OEM fan tables: 95C on - 91.5C off

In my case
NTC thermostat opens at 82C, fully open at ~89
NTC fan tables: 90C on - 87.5C off

In my case the lower thermostat helped me by reducing flkc as coolant lowers intake temperatures.
