I'm building my first PC and connecting the fans in my Cooler Master Elite 481 case. One 4-pin PWM male connector doesn't seem to have anywhere to plug in. All of the fans are already daisy-chained to the motherboard's chassis-fan and ARGB connections. Can this extra connector be left unplugged, or does it need to connect somewhere specific?

A male 4-pin fan connector is usually meant for daisy-chaining another fan. It does not normally plug directly into the motherboard, since motherboard fan headers are typically designed to accept female connectors. If you aren’t adding another fan, leaving it unplugged is fine.
Yes. As long as the fans that need power and control are connected properly, an unused pass-through connector can remain unplugged. Just make sure the ARGB plug is connected to a compatible 5V ARGB header, not a 12V RGB header.
Check your motherboard manual for the chassis or SYS_FAN headers. Those are the normal connections for case fans, and the exact header locations vary by motherboard.
So it should be okay to leave it disconnected since the other fans are already daisy-chained to the chassis-fan and ARGB connections?
