These questions are not stupid.
Cooler fuel will not add anything to the performance of a glow engine.
Thermal energy that a ounce of glow fuel can hold is very low.
What benefit it will have is that if you cool your jug and keep it cool will prevent evaporation of the volatiles in the fuel.
Just as stated above, nitro add oxygen to the combustion process. It also increases consumption because more fuel is needed to offset the nitro added. Nitro tends to give better idle at lower percentages. For normal sport flying it is not needed.
My recommendation is that if you have an airbleed carb, find a nitro percentage that works for you then stick with it. If you have a engine that you can adjust the idle mixture, then just use what is available and adjust the engine for it.
Keep your fuel cool and out of the sun light and you should be fine.

I figure the beginner forum is a good place to ask the stupid questions. I don't want to get flamed in the specialty forums.
Is there any benefit to running fuel chilled, say below 32 degrees? If you can prevent condensation around the tank, wouldn't the cooler fuel burn better and reduce crank temps (avoiding premature wear).
Does it matter with higher % nitro fuels?
Here's another one: Does the nitromethane component evaporate?
