What was the wort temp when you pitched yeast? What's the current temerature of the beer? You should use stick on "fermometers" on your fermenters so you can monitor the wort/beer temp.
Room temp is not all that relevant to be honest. Your beer could be fermenting much warmer than the room temp.
All yeast have an optimal temperature range. Generally speaking for ales you want to ferment near the lower end of the range for clean fermentation.
