散熱風扇的保護試驗（Protection）
幾個風扇扇葉連在一起固定限制其旋轉，如果風扇及電子組件不會損壞，限制旋轉的組件被解松則風扇可自動重新啟動旋轉。（All fans have integrated protection against locked rotor condition so that there will be no damage to winding or any electronic component. Restarting is automatic as soon as any constraint component to rotation has been released。）
風扇放置在垂直位置，打開開關“ON”或“OFF”風扇旋轉或停止，運轉正常則說明風扇是合格品（As fan placed at dead angle position, and the switch of FAN was changed from off to on，Restarting was automatic normal as soon as and proved that this fan is good fan）
