Turns out it work fine today. The fan reading on FAN2 enabled, even though it would not before, i'm wondering if its because FAN2 only read if there are 2 blades mining on the controller.
I also put the 16pins blade in the 18 pins controller with no problem. However the oldest 16 pins v1.1 boards does not handle 650GH/s, seem to cap out at 580~
Yes Fan2 will be controlled but only give an RPM reading if the second Blade is fitted. Good result on 16 Pin Blade 18 Pin Controller compatibility.

Yes, thank you for helping with the pinout. I had to saw off 2 pins(has to be the right one of course) off a 18 pins cable, to make it fail proof, i left the 2 empty pins on the 18 pin side, so i don't need to remember which side to put it on every times.
Just plug the 16 pin end into a 16 pin whatever and the 18 pin with only 16 pins connected in the 18 pin slot. A 18 pin blade might work in a 16 controller but i did not test.
I had issue with the custom long cables where their clamp that hold the connector in is larger than the stock one, so if you do this with the custom long cable going around you need to remove it.
