No, it's not recommended to jump a fan header as it can cause damage and void warranties.

The issue is they freeze on boot and require pressing F1 because the rear fan isn't connected. I haven’t discovered a BIOS option to turn this off. Would it be possible to bypass the rear fan header using a MB pin jumper? Cheers
