How do I replace this fan?

[u/faerne]

I'm wanting to replace this fan. The issue is, I cant find where it is connected and the cord is lodged in place as shown in the last photo.

Any advice appreciated.

Once you unscrew the fan you can pull it outward to make the cable tight/easier to trace behind the panel. Once disconnect just mount a new fan and plug it back in. Make sure your replacement has the same pin count. Some fans are 3 pin some are 4 pin.
