Will certainly be interesting to read what caused this problem.
Too much of a coincidence for all three fans to have same problem?
Surely the amount of checking has them installed correctly?
All indications point to incorrect installation/fan rotation, but the third installation was by a separate mechanic, both shops couldn't get it wrong?
Where was the power supply picked up from? Could it be an over voltage/amperage situation?
Just thinking out loud fellas, go easy.
