Default LS430 Fan stays On issue

2002 Lexus LS430 after reaching the engine temperature, the radiator fan kicks in and never stop.
The fan never stops that you can hear it inside the car and you can feel the vibration while running.
I replaced the coolant temperature sensor but it did not solve the issue.I flushed it with new coolant. My next target is the computer module. Pls advise.

2002 Lexus LS430 with 180k miles
No overheating, gauge stays in the middle.
Flushed the coolant
replace coolant temperature Sensor

Need help.Thanks in advance.
