As mentioned in the title, the computer itself works fine, but my case fan (originally a 3-pin and 4-pin molex cable, I used the 4-pin floppy adapter included with the power supply) is plugged into the SYSFAN2 port on the motherboard and hasn't turned on. Should I plug it into a different port? Do I need a different type of adapter? Thank you for your help in advance, and I can provide additional details on my hardware if necessary.
