I really don't know the workings of a UDS, but does it have a waterpan in there?
If it does then fill it with water and then freeze it solid before smoking the cheese. If it doesn't then find a way of getting a gallon of two of ice in the UDS, this will deffinately keep the temp at a lower degree.
I smoke chees quite regularly in my BWS Chubby. I remove thewater pan and fill it with H20 and freeze it solid before I attempt to smoke the cheese. I laso make the smallest fire that I can possibly get away with And still make it smoke.
