Active Cooling Mod for Replicator 1st Gen - a newbie question

[Matt Dexter]

Hi all.

I want to upgrade my Rep1, and I've been advised active cooling is a good mod to improve print quality. However - I'm an electronics newbie. I want to make this active cooling duct: http://www.thingiverse.com/thing:295317 - but I'm not sure of the requirements for adding the fan to the Mightyboard?

I read the description in the thing above, and thruit00 said that I need to solder a new MOSFET controller. I've attached a pic - is there already a MOSFET controller on the board (where the Blue '1' is to the left)? Is it simply a case of adding a 24V fan to the 'Extra' slot (shown with the Green '2')?

Any and all help appreciated.

It does appear that that picture shows an installed mosfet, and screw down terminal.  Add you fan

Thanks man. I'll post results once it's done!
