Hello. So I bought the crystal 570x case and replaced the SP120 fans with LL120 fans. I bought the 3 pack an 1 extra, I have connected them to the pc with no problems but I still want to connect the SP120 fans to the remaining slots at the top. I have an extra fan hub from the 3 pack and a lighting node slot available but I lack a cable to connect them. Where can I get that cable. plz help
