Long Answer:
When you say heat rises... That’s true if you are talking about heat in air. When you heat air it expands and becomes less dense and rises above cooler more dense air. Air is gas. It has very low density and the effect of heat has a large relative effect. In a material like aluminum, it has very high density and very high thermal conductivity. Heat will travel any direction through it very well. This is why it is frequently used as a heat sink.
The fets are attached to the bottom of the aluminum quark case and the case is designed to be the heat sink. Unfortunately it doesn't quite have enough mass and surface area to effectively absorb and dissipate the heat generated by the fets. All I did was attach a larger material mass to the point where the heat is generated so that it can conduct the heat away from the electronics. The heat sink then transfers the heat to the surrounding air. Because the rate at which heat is conducted to the air is much lower than the rate the aluminum can absorb the heat from the fets, fins are added to the back of the heat sink for no other reason than to increase the surface area of the aluminum so that effectively it has more air touching it. The fans simply move air over the surface of the heat sink to get the hot air touching the heat sink away and replace it with cool air.
Short answer.... Yes. It should work well. I'm gonna test it out tonight and I'll let you know.
I can't decide if its more fun
to make it...
or break it...
Silent...But Deadly
