Try putting the fermenter into a bucket of water. I put a Tshirt over the carboy so it soaks up the water and I fill the bucket to about the halfway mark on the fermenter.
The water in the bucket is typically lower than ambient air temp by 7-10 degrees.
No need to add any ice if the room is around 70 degrees.
Will do thanks for the advice Scottland and Oscbert. I've never had summer solstice before but is sounds soooo good. I bought a case of it last night but didn't get to try it. I have it cooling in the fridge for the brew session tonight.
