Yes, controlling fermentation temps can help slow the reaction down a bit. Fermcap is a liquid, food safe anti-foaming agent that will work well to help limit the size of your krausen. I add one drop per gallon during the boil to help control the hot break and add two drops per gallon in the fermenter. Just drip it into your wort at any time, even during peak krausen. It works well.
Beer so good, it's frightening.
