I decided not to cool for breeding this year, by the way...the results? 3 clutches in the incubator already, and more on the way. They're big clutches, too. My little girl who was 1700 grams going into the season just dropped 7 eggs. (She had the prev year off due to not making 1500 in time--she's an older girl, already proven, just small).
If I get just as many clutches without cooling, I am not going to bother cooling again.
