connection on Rambo v1.3 for 40mm Rambo Cooling Fan?

[hrodman]

Hi,

Total Noob Here.

I'm building a Rostock V3 and can't find the for sure right connection for the 40mm Rambo cooling fan on the board -- is it Fan 2? My board doesn't have the connection in the lower right shown in most documentation... Thanks for any input.

Best,
Halsey

Any constant (always on) 12v source will work.

Thanks Joe -- here's a picture:

Would this be a constant source? As far as I can tell, the answer is Yes -- but hoping to confirm...
Thx!

Page 183 of the V2 assembly manual shows that the cooling fan leads get soldered to the board at the bottom right hand near the E1 motor connector.

Thank you -- turns out the connector was left off the board -- I will solder per your suggestion

According to the manual,,, there is no connector there,,, they expect you to solder directly to the board.

I bet the OP is going nuts right now with the replies He's building a V3, and the instructions do state; 40mm fan connects to 12v AUX output
