I looked at the DeepCool hub you listed, but their
WEBSITE does not provide much useful information.
I did find a
REVIEW of the hub by Ronsanut.
The hub part of the review starts at about 5:35 on the timeline.
He states that only one port (white) has the RPM pin connected (very normal), and as such that hub will not work as an aquabus hub.
I believe there are some fan hubs that do not address the RPM pin issue, and have all pins connected, but I don't remember which.
And also, I do not know what is available to you.
You may have to build your own.
