Cooling fans not spinning to cool controller board

Recommended Posts

Hi

I want to cool my ultimaker 2 controller board. So i designed a housing

to hold 2 fans 50mm x 50mm. These are SUNON fans

12v  1.26 amps each. I have connected both fans together, positive wire from one fan

together with the negative wire from the other. the other 2 wires plus and minus are

with connector. When i plug the connector to the board marked ( FAN 19-24 V )

and power it up, the fans dont spin. I see that the fans are trying to spin, but ever so slowly,

barely nothing but trying. Am i doing something wrong ?? I am not that electronic tech savvy.

Can someone please help me.

I have attached a picture.

Thanks
