Thanks for your reply Abula.
I'm using the stock fans that comes with the cooler, they are all PWM capable, so is the pump (4 pins connector).
When I try to run the calibration from the fan xpert software, it says that the controllable range is 0.
Check that you have everything connected as Swiftech suggests, check the manual or website, in this type of pwm splitters there is one slot that its really important as its the one that reports the rpms to the motherboard, so crosscheck if all is connected correctly specially if this spot is. Else this would make the splitter just be a 12V splitter as the power comes directly from the 4pin molex.
Another thing is to check your motherboard bios, the asus mobos can also control the fan via bios, but very poorly in my experience, but if you have restrictions there it could cripple what fanxpert2 can do.
If you already crosscheck swiftech manual and check your connections and all is done properly, then do the following, run the splitter from 4pin CPU OPT header (with the pump and 1 of the fans of the H220) remember to connect also the 4pin molex to your PSU, and run one of the fans on CPU FAN header connector, and run fanxpert2 again, and the test from it, so you can see if you can control it, the only thing im trying to suggest is if the fans are fully PWM and are controllable to do it directly from the mobo header, if this works, then you know the fans are controllable and something in the splitter you havent connected correctly, this splitters usually have only 1 of all the connector report the rpms the others are like mirrors and all get controlled by the PWM singal, but if this slot is not populated on the splitter all will run a 12V that is provided by the 4pin molex connector.
