heat sinks only work to dissipate heat into a cooler environment. If the environment is the same temperature as the metal, nothing changes temperature.

You're pretty much stuck with either air conditioning, or if the air in your area is very dry, you might be able to cool it by evaporating water somehow.
khronik Reviewed by khronik on . Very Interesting High Temps Solution. So now that summer is here, both my fellow farmer and I have seen our temps go through the roof. We shouldn't be even trying during the summer, but we both thought, wtf, lets try anyway. So our temps shot up to about 35C. We've both got massive fans etc, he has a cooltube, I chopped off the room halfway up with a sheet of polythylene, but we realized that the problem is that if the air going in is warm already, you're screwed. We started philosophizing about different ways to cool things. Rating: 5
