After Sega washed the throttle, the fan frequently turned.

You need to cooperate after cleaning the throttle, because the computer has memory function and has adapted to the state before cleaning the throttle. After cleaning, the throttle opening directly changes to computer, and the common phenomenon is that the idle speed is too high. Long-term high idle speed may be the reason for frequent rotation of fans.

If the water temperature is not high, don't worry. After running, the driving computer will adapt to the state after the throttle is cleaned and return to normal.
