No. As I said in my post 2 days ago above, "The system comes with a 3-headed cable from the PUMP unit. One of these plugs into the mobo CPU_FAN header, and it MUST plug in there so that the speed of the PUMP can be sent to the header. There's a wide connector to get power from a SATA output connector from the PSU, and I suspect that IS connected or the entire system would have no power. Then there is a single output connector for the rad fans, plus a 4-output Splitter so you can connect all three supplied fans. BUT that needs attention. Of those four outputs, only ONE of them will have all four of its pins, the other three will be missing Pin #3. At least one rad fan MUST be plugged into the only output connector with all four pins, because only that output can return the fan's speed signal to the pump unit."
That is how you get the X72 system connected and working properly. OP, you have used three different fans that came pre-installed in your case, rather than the three included with the X7's system. However, that STILL means those three fans on the rad need to be connected to the fan output of the PUMP unit, using the four-output Splitter supplied.
On a mobo, each fan header can only deal with the speed signal coming back to it from ONE fan. So IF you have more than one connected via a Splitter or Hub, that device will only send back to the mobo host header ONE fans speed, and all the others will be ignored. In the case of the three fans you have on your X72 system, the Splitter used appears to impose the same limit, so no matter how you try to "see" those radiator fans, you can only see ONE fan's speed and assume the others are the same.
The speed display capabilities of the Smart Device board are not explained in the web pages. It MAY send only one of its fan's speeds to a mobo header, where the CAM software can read that info only. OR, the board may have been designed so that it collects fan speed info from each of its output ports separately and sends that NOT to the mobo header but to the CAM software using the USB2 cable connection. Then maybe CAM can actually show you all those fan's speeds separately. Or, maybe not. MAYBE CAM can only show you the speed of ONE of the fans connected to that board, and you have to assume, again, that the others are the same. If both those systems are capable of displaying only one fan speed each, then both CAM and the BIOS systems will show you ONE fan speed from the X7s system called "CPU Fan Speed", and ONE called "Case Fan Speed" representing all the fans connected to the Smart Device card. CAM MAY also show you a separate PUMP speed.
OP, you have told us you moved all the case fan motor cables from the Smart Device to mobo headers That MAY allow you to see more individual case fan speeds, since each such header can display one speed. So if you have 4 case fans, and each is plugged into its own separate mobo fan header, you may be able to "see" all their speeds. If that leaves the Smart Device doing nothing, I don't know whether you have to tell CAM to ignore it.
