Will the Auberin temp controller for the WSM fit the 14.5" model? Your Site mentions it will fit the 18" and 22" model but makes no mention of the 14.5" model. Also, if it does fit the 14.5" model should I just stick with the 6.5 cfm fan? I would like to maybe do hotter temps one day. And, what is the purpose of the optional silicon gasket? Do I need it? Will it help it perform better? Thank you!
