Hey Renny! The capacitors have more thermal mass. In Phoenix summer weather, they heat up to around 65 degC, and hold there, which works out to around a 7000 hour life. (1 hour per day for almost 20 years). They do sell thermal gap pad, but I didn't have any that was the proper thickness. There are other capacitors that are longer, that would leave about 1mm of space to the base plate, and I was going to order some thermal gap pad that is like 1.6mm thick, so the caps would push against it, but I don't think it's going to do much to remove the heat, as the bottoms of the capacitors are covered in plastic, and the people I have talked to think it's not a very good idea to remove the plastic.
