If we already know that the system in question has a quirk telling us that the system has a second fan, there's no purpose in probing the second fan - especially when probing the second fan may not work properly with systems relying on quirks. Also, convert all of the conditionals here into a single group of if/else statements. This is because there's no situations where there's more then one quirk on a device.
