25mm fan, the plug is designed to plug into the aux port of the novak escs. The fans have recesses for screws when they are bolted down, or in this case there are little stubs inside the top half of the MMM case, which the recesses in the fan locate into (including the washers, so they have no-where to excape to). You will probably need a normal Rx servo extension lead, and the fan plug should just plug in; red to red, black to black- white/yellow is unused. it might be a tight fit, so have a dremel or exacto blade on hand to trim the fan plug as needed.
