I'm not sure if this is the right place to post this so sorry if it's out of place.
I got a pre built PC from a company and i had a fan controll system in my case. my PSU broke a while ago so i got it fixed by a place near to me and he re wired my whole system but forgot to do the fan controll system. Because i am not very knowlageable when it comes to PC hardware i dont know how to re wire it because i dont know which wires need to go to where. i was wondering if someone could either tell me what they look like or post some pictures of what they look like and where they go. Any help would be greatly appreciated..
