I used it to assemble my first PC. After I transported the box in the car to the shop and back home, the CPU fan no longer runs via the CPU FAN connection but only via CPU OPT (and always at full speed). What can I do to fix this? My bequiet tower also has a USB-C connection on the front. Can I expand the board somehow (with a plug-in card or something) to connect the port? Thank you very much for your support.
