Run the Selftest once again. For SL1, navigate to LCD menu -> Settings -> Recalibration; for SL1S, navigate to LCD menu -> Settings -> Calibration -> Selftest. In case the fan also fails during the self-test, switch the connection of two of the fans, and see if the warning will be transferred to the new fan. If the error is transferred, the fan that had the warning originally may need to be replaced.
