I'm no expert but there is no need to worry. The cold will only help clarify the beer at this point. If you are going to bottle within the next week, then I'd say keep them cold and raise back up to room temperature the day of bottling. I'm actually in the process of cold crashing my Irish Ale right now and will be bottling on Thursday.
