First time using evaporation to cool carboys

[naemlss]

I was planning on having my brew fermenting inside a chest freezer for these two batches, but as all things go neither the freezer or the temp control showed up when they were supposed too. I have previously fermented in my bath tub keeping the water at a nice 66-68 degrees most of the time. So during my reading a found some people were able to drop the temps in the carboys themselves by wrapping them with wet shirts or towels. Needless to say I decided to try this route instead of running my conditioner at 70 degrees all day.

Right now my water around the carboys is at 66 degrees. The air temp is around 72 in the house. Am I cooling my carboys to much with the wet towels for the ale yeasts to have a good fermentation? I also have a fan blowing over the wet towels.

Not sure which yeast you're using, or what kind of brew, but that seems like a perfect temperature to me.

Im brewing a version of moon hill pumpkin ale using wyests london ale. We are also doing a baked apple milk stout that we came up with. For that one we are using irish yeast I think? We were planning on using yeast starters to get a big primary, but we ran out of time and just pitched the viles picked up from morebeer.
