Castle - Make A Special Edition Monster

[TexasSP]

I really don't see everyones issues with the fans. We use them in our computers to keep processors cool, we use them in our cars to keep engines cool, we use them in our houses to keep us cool. They're fantastic devices used the world over to keep things cool both electronic and not. Why is that some have it in their minds that a "properly designed" ESC should stay cool without assisted air movement? What is the real detriment of having a fan?

One big reason I like the fans is that it allows me to mount the ESC without so much consideration for air flow and especially in Texas heat keeps things operating better.
