    FanNotworking if you reversed the polarity of the fans connectors while you connected them back you short circuited them with a bit of luck you only burned the fan(s) and not the mobo connector(s) also if you have one of the fans working try it in the connector where the other fan isnt working top see if the connector its still working fine if both fans are not working you can get a voltmeter and measure the mobo connectors to check if any power is passing through and if so just boy replacement fans if no power is passing through only a complete mobo replacement will fix your issue and as always i dont advise anyone without any experience to disassemble any laptop by themselves without first knowing how to and what hardware to be carefull with when disconnecting/reconnecting everything because if you dont know just dont touch it take it to someone who knows 

    Here are the parts you might need in order to get it fixed

    Im not sure which ones are the positive/negative test them all alternate combinations to see if you get any power through at all with a voltmeter
