In the automobile, bumps in the road cause the changes in input power, and the result of slowing these changes is a smooth ride. In the electrical circuit, the capacitor takes variations in the input and creates a regulated output. The difference between the input and output energy converts to heat within the capacitor.
In most modern water-cooled capacitors, the cooling medium passes through the interior of the component. The cooling conditions in place will help determine the performance and operating lifespans of these water-cooled capacitors.
When they applied an electric field of 10.8 MV/m, the capacitors underwent an adiabatic temperature rise (and fall) of 2.5 degrees C per cycle at room temperature. With the cold sink steadily cooling over the course of about 100 cycles, its temperature dropped by up 5.2 degrees C compared with the hot sink.
In most cases, the primary thermal conduction path (the path of least resistance) is from the closed or flat end of the capacitor. Some heat also passes through the terminal end. Capacitor heat loads are small: typically 5 to 10 Watts in a 3 inch diameter capacitor.
The limited thermal conduction path out of the capacitor makes cooling more difficult. In most cases, the primary thermal conduction path (the path of least resistance) is from the closed or flat end of the capacitor. Some heat also passes through the terminal end.
Cooling a capacitor will extend its life. Alternatively, taking away more heat from the capacitor gives it more power carrying ability. Whether the goal is longer life or higher power, the solution is cooling. The traditional method for cooling capacitors is to provide physical isolation.

How do ceiling fan controllers work?
Without the capacitor the voltage does not have enough balls (for lack of better term) to keep the fan motor turning at reduced voltage. Also the fan controller has a current rating of 1.5A, and a light controller has a current rating of only 600W, I think that is where the fire hazard comes into effect.
