If I understand, the PUMP appears to work properly. When it is plugged into the mobo AIO PUMP header it seems to work, and that header does show a proper speed reading for the pump. Right? So, it works.
Now, although the system comes with a Splitter to allow you to connect BOTH rad fans to a single mobo header, you did not do that. Instead you plugged them separately into the CPU_FAN and CPU_OPT headers. That certainly should work OK, but BOTH fans do not turn. Further, If I read this right, if you move either of those fan's connectors to another mobo fan header you know is OK, that fan still does not work. Just as a final note, if you do the reverse test - plug a good fan into the CPU_FAN or CPU_OPT header - they work. Right? That would prove that the headers are OK, and the fans have failed.
If I got all that right, then you certainly do have two bad fans. You should contact the maker for replacements under Warranty.
