I customized an old 2 pin case fan the fan connector was broken so i bought one connector and connected the wire to the three pin connector but i forgot that the red and the black wire got mixed i didnt notice. After some time i connected to my motherboard 3pin fan connector. after switching on my pc i found some smoke came out from the connector of the motherboard. so i suddenly take out the case fan port while the pc was switched on. while stating my pc for the next time i noticed that no other case fans were running which i didnt touched but my pc was fine. i want the fans to be runned please help!!!

Spec
Intel core2duo e8500 3.16ghz

Probably the only thing you can try at this point is to connect the case fans to your PSU using molex connectors. It you do this, the fans will run at their fastest speed, which may create more noise. You need something like this: https://www.amazon.com/Molex-Computer-Connector-Y-Splitter-Adapter/dp/B00DU8ZZ0O/ref=sr_1_1?ie=UTF8&qid=1485288868&sr=8-1&keywords=fan+molex+connector. I'd also suggest replacing all your case fans with new 3 pin fans so that you don't screw up your polarities this time!

You could try hooking the fans directly to the PSU, via a MOLEX to fan connector adapter. IF they work, they would run at full speed any time the PSU is on, and would NOT be controlled by the MB.
