The Nexus fan is running at just over 1000 rpm no matter what load the CPU is at. Its not a problem really, its running at low temps, but would be nice to know why the mobo cannot controll the fan.

PS! the fan is connected to BOTH the mobo cpu fan and a normal 4 pin molex(?) power connector.

Is it possible to have the mobo controll the CPU fan? Any advice?..

The whole point in having dual connectivity on fans is to power them differently.

If you want the fan powered seperately from the mobo without the ability to control it via BIOS, then use the 4-pin molex, however, if you want the mobo to control it, use the 3-pin connector.

Do not use both at the same time, otherwise you could be severely reducing the life expectancy of the fan.
